Hybrids suck. Diesel rules.
I am afraid of diesel hybrids though, but I think in the long run when people start paying repair bills on their 8-10 year old hybrids that will be the end of them.
Full circle... if I remember correctly Diesel designed his original engines to run on vege oils, not petroleum.
Hybrids are a neat idea... but right now they get you in the production (energy) costs. 113 million btus to get a prius on the road.

I'm pretty sure they were supposed to run on Hemp Oil but we all know how that worked out.

Peanuts. Diesel used peanut oil. Hemp oil would work fine, as would pine oil, rapeseed, or human fat.

or human fat.
I know how to solve the obesity problem in the US.
Stop being fat or be used as fuel. ;D
Hells, yes.
Now who's gonna help me retrofit my Volvo? [evil]

free liposuction and it would smell like delicious ham EVERYWHERE.
You mean clean fuel though, right? That article just talks about petroleum diesel becoming more popular, not diesel cars burning more bio-fuel. The EROI on biodiesel isn't quite high enough yet to make that feasible, as much as I would like that to happen. It is if it is free (WVO), but not if you have to buy it.

Is that a lot? It takes 200M BTUs to get a Hummer on the road.

A Hummer isn't a typical vehicle moreover, they are defunct.
I guess my point was 113M BTUs is an arbitrary value if there is no context - is that good or bad? How does that compare to other cars? And ultimately, if we are counting tons of carbon, BTUs, or dollars, how does the Prius or whatever car, diesel or gas compare?
Anyways, as you were. Back to your regularly scheduled diesel car thread programming.

So that's why used french fry oil works?
Mythbusters - Cooking Oil as Economical Diesel Fuel (http://www.youtube.com/watch?v=QEX1YFXYTdI#normal)
The restaurant owners around here have a co-op of sorts and pool there veggie oil for use in their diesel vehicles.
One local mechanic has made a fairly lucrative side business doing conversions...tank and heater install etc.

Beats paying someone to throw it out for you.

WVO . Waste Vegetable Oil and yes it works great.
Is the diesel that is used today the same as the diesel that was used 20 years ago (I'm talking in the US). I vaguely remember (since I was 5 or so) that my parents didn't like to drive their diesel Volvo because it got shit mileage. But I remember a more recent thread that had some mileage talk in it mentioned how diesel now is "better" and mileage is pretty good. If the diesel now is different than the diesel of 20 years ago, does WVO still work in a new car or is that asking for trouble?
If you properly filter and pre-heat veggie oil (in cold temps) it works just fine.

fixed it for ya!
Mileage wasn't as much of an issue 20 yrs ago. Gas cars got 10 to 20 mpg and that was great. Diesel cars got 15 to 25 and everyone was stoked because diesel was half as much per gal.
That being said, the old Volvo diesels had a tunable MFI that could be leaned for better mpg or enriched for more power. Same on the BMW 528s. Most people tuned them for more power and forgot about it.
My neighbor has a 240 diesel and pulls 35mpg.
I see I'm ahead of the curve. 8)

My understanding is veggie needs no heat above say 70 F

Iz, do you have a wvo setup for your vw? If so, do you process your own? I'm in search of an f350 diesel and have a couple buddys with waste oil connections. Vegistroke seems to be the system for the Fords.
There's a local guy on craigslist selling 275 gallon water/liquid storage tanks for not too much dough. Would be nice for keeping some wvo.
I've also seen processing systems for used vehicle oil and trans fluid. A centrifuge is used to clean out the nasty bits.
Diesel Rocks!

Generally, you have two tanks. Start the tank on petrodiesel or biodiesel cut with kerosene and then switch over. This is even for summer as the WVO doesn't start as eagerly as regular #2.

I realize you start it on diesel.
I was just talking about the veggie being thin enough to 'run' at about 70 without the tank heater running.
In the winter here the veggie will solidify without the tank heater.

gotcha!
Biodiesel is a product that has been refined as an automotive fuel, and is as pure as diesel. The difference is it a vegetable product, not a petroleum product. It is taxed as an automotive fuel. Warranty permitting, it function like diesel in your car or truck. Depending on blend BTU content is a little less or even about the same as diesel. A few years ago I met a woman who worked for a biodiesel supplier. Her Golf diesel ran most of the 60K on the odometer on biodiesel without a problem, and the exhaust (the car's, not hers) smelled like french fries.
"Grease", or reclaimed cooking oil usually is not taxed since it is not an automotive fuel but a waste product. I said usually because few years back some poor soul was hit with a bill for a bunch of money and a fine for not paying tax on the waste cooking oil he was running in his pick up. A "grease" vehicle will require a separate tank, filtering system and switching device since it will need to be started on diesel. A heater is also a good idea if you are in a cold part of the country. Btu content is also a little less.
Back in the '70s the Cadillac and Oldsmobile diesels may not have done so well in fuel economy or reliability but the diesel rabbit sure did. 50+ MPG was not uncommon and they ran for a long time. My brother in law had a '79 Mercedes S class diesel (in other words, big and heavy) that got a consistent 28 MPG.
Expect 10% biodiesel at a pump near you soon. This will solve two problems simultaneously. It will extend our fuel supply and help dispose of cooking oil which is considered an environmental hazard. Bio fuels are a good idea as long as they do not compete with food supply. Well, except for E10 and E15 [bang]

ALL of the Bio-D around me and what I have heard of is produced from virgin soya. I haven't heard of any reclaimed WVO being used for pump bio-D. Have you read differently?

Good catch, counselor! I should have said could help, or even hope will. I could quote a source who told me his company does, at least to some extent. Since he is a marketing person I won't. In the US virgin soy is the predominant source. It appears to be a supply issue. Hopefully this will change.
