Diesel vs Biodiesel Pricing?

2008-07-15T21:08:00.001-04:00

With high oil, high gas and even higher diesel prices, many Biodiesel enthusiasts are having a field day with "I told you so", but this would be a mistake. Though the biodiesel price seems coupled to dino diesel pricing on a competitive and resources level...they are actually surprisingly unassociated for many customers in the industry. And generally, customers "happily" pay more.
Consider that the majority of the transportation biodiesel is sold to government or private fleets. They are often have a reason for the extra "effort" (at least at this time) for running bio or a blend, usually health/patriotic/local economic reasons, but more frequently now a government mandate. These are not the same market forces on petroleum fuels.
Often I recommend small producers or distributors to raise their biodiesel prices as the number one way to improve their business model, even against their instincts in times like this. Consistently the feedback is shock and pleasant surprise. Customers expect to pay a premium (at this time) for a unique fuel (at this time). The negative pricing feedback that forms impressions on biodiesel retailers often from "prospective" customers on the phone, the equivalent of tie-kickers and window shoppers. Real market analysis reveals a true picture: price is decoupled from petroleum, and premium pricing is fine, and good for the fledgling industry. And soon the market will reflect that.
So don't get too haughty about your cheap biodiesel...expensive biodiesel is actually better and probably inevitable in the near future. Sorry 'bout bursting your bubble.

Food vs Fuel? 1st vs 2nd Generation Biofuels.

2008-06-05T13:59:00.003-04:00

When discussing biofuels, it would be better to educate on the difference between current "first generation" biofuels (corn/sugar ethanol and soy/rape biodiesel) and future "second generation" biofuels (cellulosic/crude biomass ethanol and BTL(biomass-to-liquid)/crude biomass biodiesel). Current first generation biofuels are indeed rather unsustainable in large production but do provide an entryway and market demand for the higher-overhead and R&D needed second generation fuels.

Second generation fuels are going to be orders of magnitude more efficient and sustainable, deriving their biomass from non-food farming and management of un-cultivatable lands. Some technology still needs R&D (cellulosic ethanol is probably 5 years from mass production, algae biodiesel is in R&D stages) and other seed money. F-T (Fischer Trop)biomass-to-biodiesel technology is older and tested but requires a large overhead and scale to make profitable. The German government has provided overhead and there is a F-T based BTL pilot plant making biodiesel from crude (non-food) biomass: http://www.choren.com/en/ So, while these first generation biofuels are temporarily linked to the larger food problem, they are also opening up the route to more efficient biofuels that will decouple them from food issues yet bring the benefits of energy independence and lowering environmental impact.

Getting back to Blogging

2008-04-23T17:27:00.003-04:00

Well, sorry. A lot was happening. New Baby (Yeah!) new jobs and bunches of projects. Our biofuel (wvo) heating project is continuing to save money in several test houses. In our humble abode...about $500 savings in 2007 calender year...more expected this year with the colder winter and higher fuel costs.

On the Jeep side, important news. I spearheaded an attempt at a recall on the fuel filter assembly. The fuel heater (mostly un-needed) element projects into the uper housing which, due to the all-vacuum (no lift pump) nature of the fuel system, often contains air. This can over-heat, burn out and cause an air-leak. If you have a CRD Libby, take a look for upper plugs and leaks. Pumping the primer will often squirt out fuel, even faster if the element wire plug is pulled out. Bad News! Extra air in the system is the least of the problems (and it is a big problem). Leaking ful could potentially start a fire, and there is one possible case. If you have a Libby CRD, you probably already know to go to http://www.lostkjs.com/, check under the CRD section for more info. The NTSB gave it a pass, but that doesn't mean much, they usually don't do much until someone dies. So, unplug those fuel heaters! Note: this is not a biodiesel issue.

On fuel pricing, Diesel at the pump has actually passed the price of biodiesel being deliverd to my house by $0.30 . So now there are even less reasons to not love biodiesel!

A brief update...

2007-09-11T14:57:00.000-04:00

So, let's catch up. Here's whats new to the BiodieselJeep and the biofuels family:

-The BiodieselJeep is running fine. We moved to a about 30-50% splash-blend for the winter and have kept at that since then. Splash blending (for those who want to pick up some more biofuel-lingo) just means that you dump it in the tank, no muss, no fuss. That's one of the great things about biodiesel. Why 30-50%? My biodiesel container is 5 gallons, and I dump it in when it gets mid to low. No science here, just convenience.
-The BiodieselJeep mileage is improving. Diesels generally get better as they break in. There is a simple mod that also got us another 1-2 mpg. Around town as a baby-carrrier the Jeep gets 23 mpg consistently. Compare that to any other mid-small sized SUVs. Which brings me to another point: The curb weight of the Jeep with the diesel option is alot closer to a mid-sized SUV than many of the small SUV's it gets compared to. A CRV? maybe. But often it gets compared to the RAV-4, which is sooo tiny. Not fair, I say! Highway with a big load and driving 70 mph: 26 mpg. At 55 we get near 30...but that just isn't realistic.
-Meet the "new" Jetta, same as the "old" Jetta. I crashed the black Jetta. I cried and cried; that lil' honey could run. Cried until I got the insurance check, which was more than I paid for it!Diesels are selling for ridiculous amounts. so my insurance company paid out a market price and that took the edge off. I bought a white Jetta TDI, same year, same mileage but with more doodads and a moon-roof. To make it even better, I sold the wreck to some clever boys from Vermont who wanted to slap together a diesel hybrid. Hopefully as you read this, the FrankenJetta is haunting the Green Mountains, terrorizing gas stations with inhuman mileage. Bwoooaaaahaaahaahaaa!!!
-Can't drive 55. Look, let us be honest. You and I should drive slower if we really want better mileage. All the statistics are very clear: every 4-5 mph over 55 drops your mileage by at least 1 mpg. But in my state (CT) highways are 65 mph...and everyone drives 75. Now, the white Jetta has bigger injectors and stuff, which means it really wants to fast. Fast as in not dangerous but fast as in sorry-officer-I-think-my-speedometer-is-broken. Still, I never get below 41 mpg. I could be getting close to 48...(someone is doing math right now...yes...naughty boy). The guilt haunts me at night, but sporty turbo diesels combined with autobahn engineering makes for irresistible fun.

What is in a Name (or URL)?

2007-09-07T12:14:00.000-04:00

We lost our domain name for a while, and that meant very little blogging. To make a long story short...never use lowcostdomains.com or wyattwebb services...pure evil. Anyhow, more posts to come. The next post will have a long awaited (I am sure...) update on our research and our biodiesel powered vehicles.

Berlin Fair contributes Biofuels

2006-10-27T12:03:00.000-04:00

The folks at the South Kensington Fire department donated all their used cooking oil from their booth at the Berlin Fair. If you've been to a country fair, you know there's a lot of frying going on. Thanks Guys! Your oil will probably heat my house for at least a month this winter.

Learning to use raw oils will be a key part to our biofuels future...if only because raw oils will always be cheaper than processed oils (like biodiesel). Many current commercial waste oil furnaces can burn straight waste veg oil with some filtering, and our experiments on using current home furnaces is progressing well.

Perhaps by next year many homes in Berlin will be heated by biodiesel or waste veg oil...that would be something worth crowing about at the next fair!

B-DJeep and more Biofuels Research

2006-09-22T13:34:00.000-04:00

We had another interesting day of education and research, this time into home heating furnace use and biofuels. Here in the North East, petroleum home heating oil (basically diesel fuel) represents a large portion of our petroleum use. I have been working for many years now with several groups on biofuels in this area. Fortunately, home furnaces are relatively cheap (as in, not a $25,000 Jeep) and forgiving pieces of equipment, and lend themselves to rough experiments. So far the B-DJeep house has been running on one form or another of blended fuels for over a year.

Prof. Gene Bartholomew and the student at Porter and Chester Institute helped do a comparitive series of furnace tests of 100% Biodiesel, Biodiesel blends, and some new experimental biofuel blends. What was most significant about these test was that this was the first time in the US that there has been a side-by-side comparison of efficiency, flu gases and motor draw for biofuels under controlled conditions on several equipment platforms. Gus Kellog from www.greenleafbiofuels.com was there to supply the ASTM biodiesel, as was Rich Hosley from www.halehillfarms.com, a biodiesel blend heating oil supplier.

The results were surprising to everyone. The literature and previous experiments with home-brewed BioD led most people to expected difficulty with 100% Biodiesel, but the ASTM commercial grade Biodiesel lit easily under stock equipment previously set to run on No.2 Diesel. The same went for the experimental 20% blends of cheap biofuels. And a bigger surprise was the efficiency of the fuels. On each of the biofuels including 100% biodiesel, the variation of the efficiency was under 5% from No. 2 on every furnace tested. Some biofuels testing higher than the baseline for No.2 diesel! A variation of 5% is pretty standard error margin, one can expect that amount of variation from repeated firings of ANY furnace using standard fuel.

What is exceptionally nice about the efficiency data is that this breaks some economic barriers and stereotypes about blended fuel uses. For instance, a blend of 50% biodiesel isn't very helpful if it has half the efficiency of No. 2 and makes you use twice as many gallons to heat your hot house! I honestly expected without changing the settings on the furnace, these fuels would perform some when below 7%. Most of the chemical energy values of either Biodiesel or other vegetable oil fuels are generally 5% below comparable petroleum fuels. The added viscosity of these fuels would make us think that the spray pattern would be slightly degraded, further reduce the burn efficiency. But not so. Apparently, viscosity is rather easily tolerated in furnaces, and the high inherent oxygen content of these fuels makes up for some of the energy differences in these furnace situations.

The students who were working toward HVAC certification will eventually be seeing these biofuels in the field, and they were interested to work with the new fuels and participate in the research. Thanks to Gene, we also will be able to move forward on several projects related to the experiment biofuels knowing that we have efficient blends for general use in homes.

On this blog we will keep certain projects below the radar for commercial reasons. But we WILL let you know in general terms about our research... Maybe being aware of new alternative fuels research will give you hope for the future and to inspire you to make a move for the better in your own home. Your dollars, your fuels, your country, and your future. Think about it.

Pleasure doing business with you...

2006-08-08T14:16:00.000-04:00

Looks like the Libby has gotten a lot of highway miles in this summer, and we are at the end of barrel #3. A total of 165 gallons of biodiesel! Consider this: that's about $511 of dino diesel we did NOT purchase this year. Where does that money go that you are spending at the pump? Well, some is taxes, and some goes to the people locally distributing and selling the fuel, but it is estimated that 20% of every petrol-dollar, or $102 of that $511, goes out of the country to the mideast to pay for the oil imported to meet our growing need for fuel. We import over 80% of all our oil used. And guess who those mideast oil guys are? And what do they fund with this money? $102 buys you a lot of explosives and bullets on the streets of Bagdad, Iran, or Gaza. Osama Bin Laden and his family own one of the largest oil companies in the mid-east, guess what they do with their money? Pick you least favorite nation...and then realize tha YOU are giving them money every day.

I'd rather that $102 go toward a U.S. farmer growing crops somewhere in this country. Perhaps my money is paying for some farmer's family lunch right now. Have a beer on me, guys. Pleasure doing business with you.

Jealous of the Jetta

2006-08-02T14:28:00.000-04:00

So says my wife; "Since you got the Jetta, its like you don't care about the Jeep anymore. You'll hurt its feelings." Well, now, you see its complicated. Jeep, you'll always be my first Bio-vehicle and that means a lot. Its just that, well, the Jetta needs my attention right now. Its not like I'm just running to some young thing, the Jetta's older by years. But Jetta gets 45-50 mpg and I drive it everyday, and now that it is slowly getting up to speed on biodiesel, it is going to need some time and attention. You're mature enough to understand that, right? Don't be mad at the Jetta's sleek lines and snappy acceleration...it will NEVER have the family capacity that you have. Plus, who is my favorite off-road vehicle every made? Who can haul 5,000lbs without batting an eyelash?

What, well yes I did have my hand under the hood. But that was strictly mechanical. You know, a maintenance thing? And those receipts from the auto store? Just a little something...just replacement parts. Like I never buy YOU stuff?

Don't be that way. C'mon, lets go for a drive and flip-off the gas stations. We'll both feel better.

Below the Fold

2006-07-28T14:49:00.000-04:00

Helped a nice fellow from the Merdien Record/Journal on a front page piece on alternative fuel usage in CT. This blog gets a mention (perhaps that's why you're tuning in?) and Cliff made a fairly accurate report, to his credit. Most reporters get facts wrong, and though my quotes were a bit offf, the over-all information in the article was spot-on. More importantly, GreenleafBiofuels.com got a mention and people will hopefully be able to get dirrected to quality BioD in CT if they were inspired by the article.
Meanwhile, due to some wacky lady totalling our other car, we were able to purchase a used Jetta TDI (diesel) for the straight vegetable oil experiment. Soon the entire family fleet will be on American-made, renewable fuel...and we'll be saving money, to boot!

Biodiesel Factory in CT

2006-07-20T20:14:00.000-04:00

Late posting is still posting, sorry. I got invited to the grand openning of the first Biodiesel manufacturing plant in my state of CT. Governor Rell (in Red) and a surprising amount of local press was there. The company, Biopurinc.com, is a modest faciluty starting out under half a million gallons per year. This will probably not effect prices in CT as Biodiesel demand is growing much faster than this facory can increase production.

However, this may help our Energy Independent Farm Project. We're hoping to get a model; farm growing enough oil to power its own tractors, increase profit margins and hopefully stabilizing overhead expenses. Farmers pre-sell their crops before they are sown, but variation in energy costs can eat up these profits before harvest. The CT Biodiesel Consortium thinks that, with a addition infrastructure, farmers could turn their oil into biodiesel. I'm working on an angle used in Europe, which is to use the oil dirrectly without the expensive biodiesel conversion. Either way, it is a great project. More details on asoon to come link.

Batting .371 for America

2006-06-30T16:37:00.000-04:00

So far, we've displaced a total of 110 gallons of petroleum diesel in the Jeep. Feels good. We've also displaced close to 80 gallons of dino fuel in our hot water/heating furnace with various biodiesel and waste-oil blends experiments. The veg experiments in the furnace are far from concluded (there are many people working on this) but about 10-15% straight vegetable oil can be blended with regular home heating fuel (which is usually a dirty form of diesel) without much noticeable issues. There are people working to do cheap adaptations of their furnaces to run 100% veg oil, but it is experimental. 100% biodiesel can run in a furnace with usually only a nozzle and pressure change (assuming you have a modern furnace with an indoor tank)...but often a pump must be replaced with one that has seals resistant to the solvent effects of the BioD.

So how are we doing over-all? Well, we still have the Ford Focus running regular gasoline, and the furnace use is usually about 75 gallons a month averaged over the year. So of the about 175 gallons of total oil fuel products we are using per month, 65 are biofuels of some sort. That's 37%. I consider this a realistic goal for an average oil-intensive New England family such as our. We will be doing better when I switch cars, but it still feels good.

Consider this: over 30% of our oil use in this country is imported from the middle-east...and our money ends up in the hands of people that don't tend to treat us very well as customers or people. I'll go into this and my personal feelings on that region another time. Our family has theoretically cut them out of the picture.

And that is something that makes me feel really, really good. Happy July 4th!

Biodiesel Day (we are in good hands)

2006-06-27T12:22:00.000-04:00

Back in May I had the privileged to attend Biodiesel Day at the Greater Hartford Academy of mathematics & Science. At this high school, students had initiated and executed a series of projects to grow their own fuel-stock (algae) and make biodiesel. The scope of their ambition, imagination and accomplishment was staggering. This Biodiesel day was a presentation of their year's work to about 250 of their peers and faculty. Without any teacher input or suggestion, this project had been planned, managed and developed into the basis for real advancement in developing what will eventually become a primary fuel-stock process for the US and probably the world.

Some history: the National Renewable Energy Laboratory had a project to investigate potential renewable fuels and had settled on Algae farming as the fastest growing, least land intense and most economical of producing usable fuel....Algae-oil based biodiesel. The project had reached a point of categorizing the algae species most useful at producing plant oil and running a test pond to determine the productivity. Then the project was ended in the early nineties.

What is amazing is that these high school students, who were interested in renewable fuels, have researched and found this promising yet "lost" path of biofuel research on their own and initiated a program to pick up where the government research left off. There are only a few University level experiments running in this area, almost none of which are in the US. Only this month did a few petro-chemical companies announce their algae research divisions (we will see how many pan out). Algae has been determined as the only way to product enough fuel domestically (there isn't enough land for soybeans) to meet our current demand for liquid fuels. (more here: http://www.unh.edu/p2/biodiesel/article_alge.html). When you consider the importance that algae biomass will play in the future, the fact that these students are pioneers in the field is even more impressive.

I was asked to speak and presented a brief overview of current biofuels science, with an aim to put the scope of their work in context to let them realize just how cutting edge their research has been. Gus Kellog of www.greenleafbiofuels.com also spoke more specifically about biodiesel and the roles it could play in our economy and in helping our state. The students presented the summaries of the progress in their work so far, and we also went out to see and smell the Biodiesel Jeep. Afterwards, Jake Mendelssohn, a teacher who shared in overseeing the project, showed me around the student's labs.

These are lucky kids with a chance to work in a school with big budgets, stunning facilities, and amazing teachers. But we are more lucky in that these kids may just be the ones to free this country from foreign oil, save our economy and keep the world in decent shape as you and I become older. Thanks, kids!

L.O.S.T. for a while

2006-06-21T10:32:00.000-04:00

As my friend Amrita pointed out: it isn't much of a Blog if you don't update it. Sorry, but the Biofuel Family has been busy. Most importantly, it was a BIG birthday (not telling which) for my wife, so much partying and rejoicing was being planned and enjoyed. The Biodiesel Jeep has also been getting to the beach a lot, and hauling paragliders (www.ctchutes.com) to satisfy my other non-biofuel obsessions. The little man pitched in to help clean the Jeep one hot day...note the sippy cup on the bumper.

In mechanical news, the MIL (check engine) light is still on, and I sussed out the OBD code p1104 with the help of www.lostkjs.com forum...The Liberty Owners Special Team. This is basically Car Geek Heaven, so naturally I spend a LOT of time there learning about all that you could want to know about Libbies, diesels, nifty modifications, and other biodiesel jeepsters! This is just the sort of thing the internet does best; gets experts and enthusiast together and lets them learn from each other. If you own a specialty car, you probably already have found a similar site, The L.O.S.T. site has some really great experts floating through, so I suggest Libby owners tune in there regularly. The deciphered code indicates a very common EGR valve issue (in the exhaust/emissions system) which apparently a common issue with these Libbs and has nothing to do with Biodiesel use. So I was wrong, it was not a fuel-quality issue from when I had to fill it with NY Dino-diesel (as it was in the last time the MIL light popped. Sounded nice, though! The dealer will fix it Monday.

I'm itching to ditch my other petro-burning car. This is the one *I* end up commuting with (marital politics are VERY tricky), and it pains me each fill-up knowing I could be in a biofueled car instead. The little 2002 Ford Focus is very efficient for a production car (30+mpg) but, as you may have guessed, dino fuels just aren't my bag. I've been hunting and visiting several potential old Mercedes and VW's for a SVO (Straight Vegetable Oil fuel) project car. Why not use the Biodiesel or make my own? Well, cost is an issue, but curiosity is the bigger factor. There are expanding studies on SVO use in "tougher" diesel engines..And the data is pretty impressive. Using harvested oils directly would be a more efficient way to use the oil instead of converting it into Biodiesel...But there are many issues. I'll get into that in further posts and links, but in the meanwhile, if you are curious, visit the company with the best current research on SVO use in transportation engines is www.elsbett.com.

Another factor is that I've been collecting and processing large amounts of waste vegetable oil (WVO) for my other experiments with home heating oil (HHO)...So I've got a lot of potential fuel sitting around. HHO is basically dirtier diesel, and in the North East HHO is a significant portion of of the total yearly petroleum use. A home furnace CAN use blends of nice thin Biodiesel&HHO without modification (Ain't Biodiesel grand?), usually a 20% blend (with a few adjustments some can burn higher consetrations of biodiesel though that isn't recommended at this time nor is it commercially available). Our current home hot water and heating furnace burns a 20% blend of Biodiesel right now...ordered and delivered from www.halehillfarms.com. Nice and clean, no extra expense (actually, it is cheaper). But what about getting even cheaper, how about raw products? Several hefty commercial "waste oil" burners can burn substitute oils, including thick engine-oil, transmission fluid, 100% biodiesel and even vegetable oil (www.kagiheat.com). These waste oil furnaces burn very hot and very clean and help "recycle" on the spot; this is what they do with all the oil from your fluid changes at you local mechanics/lube shop. But your home heating furnace can not use 100% waste oil, as the home burners can't take very thick oils ( and there are usually regs against it). But here's something most people won't talk about in the bio-fuels world: Biodiesel is really just thin vegetable oil. From an energy standpoint, they contain just about the same amount. Vegetable oil has more complicated fat chains and is thicker and might have more impurities...But that doesn't matter much in a furnace. You can burn dirt in a furnace. So there are groups burning 10 ,15 and 20% blends of vegetable oil with HHO, including recycled and cleaned waste restaurant oil. We ran an experiment for the last two years of up to 20% vegetable oil (virgin)without any problem. Several restaurants (including www.angelosonmain.com) are contributing oil for further local experiments with used, filtered oil. This used oil is essentially free, so displacing 20% or expensive, dirty dinofuel is not only better for everyone's lungs..its cheap and easy. Good idea? Yep.

But don't rush and try it yet...There is a large network involved in testing these blends in a lot of furnaces across the country. Breaking car is one thing...messing up your house is different. Let us take the risk under controlled conditions with the consultation of burner manufacturers. For now, try commercial grade Biodiesel in your car, and a 20% blend of commercial grade Biodiesel in your furnace. And stay tuned!

Biodiesel Mileage Report: $0.16/mile

2006-06-03T13:39:00.000-04:00

Results from my first measured test of mileage on 100% (B100 unblended) commercial grade biodiesel. Since I don’t have a way to accurately measure the biodiesel that I hand pump from the delivered barrels, I had to (argh) re-fill with petro diesel at a station to figure the amount I used.

Vehicle: 2005 CRD Sport, 12,000 miles aftermarket roof-racks (unloaded), hitch rack (fully loaded), two adults, one child and one golden retriever, tons of camping and whitewater gear.

Conditions: 75% non-flat highway, 25% mountains (CT to upstate NY). Highway speeds at 75 mph (2200 rpm) on cruise.

Biodiesel Mileage: 21.8 mpg (+/- 2mpg based on different method/person filling tank)

Cost per mile on Biodiesel at $3.49/gallon: $.16 !!!compare to $.18 per mile in a gas liberty at $3.09/gallon betting similar ”city” mileage

Interesting note: soon after filling with truck-stop petro diesel in on the MA/CT border, the check-engine light went on. This has only happened once before...when I filled up with petro diesel on the NY/CT border. I think that they have crappy diesel in that region.

This data is stand-alone, there is no way for me to compare this biodiesel performance to petro-diesel unless I go an make the same trip again on petro-diesel. However, it DOES let me know that my mileage is reasonable..and my cost per mile on biodiesel IS competitive with other vehicles on non-biodiesel.

110 more gallons, feelin' good!

2006-05-22T14:23:00.000-04:00

Gus Kellog delivered more BioD on Saturday while I was out at the CT Boogie (pics at www.ctchutes.com). This should last us the summer, though a lot of camping trips are planned. Still wish I could figure out a convenient way to accurately measure my usage....this weekend we are supposed to go on The Big Memorial Day canoe trip and it would be a great chance to check it.

If you live in CT, you should know about www.greenleafbiofuels.com and Gus Kellog. He's the only operation selling (or delivering) retail quantities of ASTM quality 100% Biodiesel. Best part is, FREE delivery. His business is probably growing faster than he expected, so get in early. Remember, someday BioD will be as common as gasoline...and who has gasoline delivered to their house? Sooner or later, we will be filling up with biodiesel at every station, which will be great...

...but the pleasure of filling-up out of a pump at your house can not be underestimated. Its not just the many Biodiesel-is-great feelings, it is also something about feeling more independent when you have your own supply of fuel...I'm sure I'd feel it with a tank of gasoline in the garage. Whenever you want, just go and get some! Ahhhh. Like having a kegorater. And who doesn't feel jerked around by the gas stations? Feeling good and independent is part of what this whole union of Biodiesel and Jeep is about.

Ahhh.

55 Gallons....burp!

2006-05-19T14:37:00.000-04:00

The Jeep finished its first 55 gallons of ASTM Biodiesel. Initially we broke it in with blends but by the end, it was only getting the good stuff. Many folks off the Yahoo CRD list have been swapping BioD experiences, and all have had positive results so far. Everyone indicated improved engine sound, no smoke, and a better smell. I noticed all of these.

One person indicated better mileage, but this is something we haven't quantitatively tested. At this point (10k on the car) most diesels are just breaking in, so mileage can generally improve over time ANYWAY (gotta love diesels!), so we will wait until another long-trip opportunity can let us compare on an out-and-back. Also, we don't have any meters for measuring the BioD, so we can only measure the amount we re-fill with dinodiesel from a pump. Any suggestions on an accurate way to measure biodiesel at our house would be appreciated!

Jeep Bioblog goes live

2006-05-10T14:33:00.000-04:00

Imagine the thrill of returning to this blog daily to find more drivel from your favorite fuel fanatic. Sorry, too good to resist. Also a place to leave comments and share ideas. More to come.
