said by Styvas:lol! Can regular diesel engines run on bio-diesel? I suppose that makes sense but I'd never thought about it.
old style diesel's yes (although, i'm not sure of the exact process).
modern "Clean Diesel" engines though, no...you can use some bio-diesel in a modern diesel engine, but no more than B5 (5% bio-diesel)...modern diesel engines are more complicated than older style ones, which is one reason why the older ones were actually a little better in terms of fuel economy, but it's the emissions...the high pressure fuel lines, special sensors and other emissions related components on the newer units than can be damaged using bio-diesel.
