Re: bio diesel
Theres a big difference in bio diesel depending on what its derived from. Diesel made from animal products will gel up and must be heated. You also have to start and stop the engine while running regular diesel, so the system gets alot more complicated. Vegetable based bio diesel is much better. as allready mentioned, you will have to switch out your fuel lines and add filters, but thats really about it. Older diesel engines, especially a larger on like your Cat, are built to run on very low grade fuel, so it ought to take to it just fine.
two major plusses: the biodiesel is actually better for the engine, as it has more lubricity, and it smells like french fries!
one more story I heard through the grape vine.
Theres a guy putting straight unused vegetable oil in his early 90's dodge Cummins truck. He buys it by the 55 gal drum and around 55 cents a gallon.
