veggie oil?? (was RE: Audi 5000 Diesel conversion)

[Fred Munro]

Actually, you can run veggie oil as 100% fuel using an engine coolant heat
exchanger to heat up the veggie oil to reduce it's viscosity. The better
quality fry oils actually have better lubricity than diesel fuel. You need 2
tanks - one for diesel and one for veggie. You start the engine on diesel
and switch to veggie after it has warmed up. You switch back to diesel and
purge the veggie before you shut the engine off. Filtration is an issue; you
have to filter the fuel before adding it to the tank and run an in-line
filter as well.

Veggie is currently "free" in that restaurants usually pay to dispose of it
and are happy to give it away. Once enough people convert their Jettas to
veggie burners, the law of supply and demand will take over and it won't be
free no more :)

Not exactly "free." It can work as a large percentage of fuel, but the
lubricity isn't the same (let alone the filtration issues). From what
(admittedly little) I've read in the technical journals, engine longevity is
severely compromised. But hey... old '80's diesels are CHEAP and if you can
get the used veggie oil free, all you need is some filtration and several
disposable cars! =)
If I had a fleet of old VW rabbit "oil burners," I'd try it out. Will make
everyone behind you hungy for french fries. ;-)
