My brother -in-law owns a lot of restaurants in upstate NY. My nephew bought an old Mercedes and converted it to use cooking oil from the fyrolators for fuel. It worked! Saved on gas but smelled like a french fry where ever he drove.
Actually a lot of people like the idea of turning trash into cash. In this case they produce a finer product than petroleum as it burns better and is better for the environment.It is so fine it has been used as fuel for our air force super sonic jets. My point would be doubling up on savings and further reducing emissions by using the wildcat on a diesel fueled by biofuel. go HLNT
