Deisel motors can easily be modified to run vegetable oil or any other cooking oil for that matter. But its supposed to be run as a gas, not oil. Many vw TDI guys have done this. The car smells like a Mcdonalds if you're driving behind it.

 

pwn3d indeed...

 

Veggie oil costs just as much as regular oil it has to be fake.

 

When I was in high school, I told a kid that asked how to change his oil that he needs to remember to use his garden hose to rinse the old oil out of the engine. Believe it or not, he did. Needless to say, his parents were not impressed!!
