    this is sadly true. Due to our current oil cravings our governments foreign policy is driven very much by this valuable resource. One reason people think or current policy makers oppose accessing fully our potential oil reserves is that the government receives more funds by importing and than it would by "exporting" to itself.

    If bio diesel and other such alternative fuels such as propane became big enough to take a chunk out of the oil money pie. We may see those products get taxed to keep diesel etc. competitive.

    Try 50% diesel, 40% oil, and 10% methanol/Ethanol

    I wouldn't run anything other than low sulfer diesel in my machines. Especially anything that is EPA compliant. Oil might work in older diesels (I'm sure my 6.2 would love it) but on newer diesels I'd be afraid to wipe out a fuel pump, computer or an injector. Maybe I'm wrong......

    I'd be wary of pure bio-diesel, but 50/50 should run in ANY diesel engine just the same as ULSD. That being said, bio-diesel is more prone to bacterial growth over long term storage (not that that should matter much in this sort of use).

    Now there is a big difference between bio-diesel and recycled fryer oil. You can chemically process used cooking oil into bio-diesel, but without the processing and filtering, you run the real risk of doing engine damage if you take oil straight from the fryer (although it may run for a short while).
