What rating would biodiesel cars get : SULEV,LEV, or worse ?

Question

( I know that the rating would probably change depending on the type of substance used to make the fuel, as well as the amount of the fuel used - or Miles Per Gallon. )

Answer 1

the same as a normal diesel engine.

it burns slightly cleaner than PD but you get less MPG too.

so you have to burn more to compensate.

Answer 2

wat?
