Can Alt fuels be better for diesel engines instead of biodiesel?

Tom W asked:


I have found a site that boasts no engine modifications needed as well as by using their additive, you can use restaurant grease to fuel any diesel engine. Is that possible or true?

  1. yes it’s called Bio-diesel!!!!!!!

    Basically restaurant oil grease is purified and added with 20-80% diesel to become Bio Diesel.

    Pure 100% cooking oil can run a Diesel engine however it’s hard to ignite at times and clogs pumps and filters real easy.. that’s why most bio-diesel is called B-20 or 20% cooking oil and 80% road diesel for. It helps cut the need on the road diesel but doesn’t give as many issues as pure bio

    You can also run a diesel on used transmission oil but wouldn’t recommend it…
