I was filling up my (GM diesel truck)tank last night and a new Mercedes is park beside me. I started fueling up and the owner of the Mercedes comments that diesel is still extremely high. I didn't notice he was driving a turbo diesel sports car.
He then told me to check this out, Mind you he has olny put 10 gals of diesel in his vehicle before hand. He opens his trunk and pulls out 10 gals of used cooking oil. He pours the cooking oil into the fuel tank. I had asked him if the car was converted, he replied "no the conversion is about $1500 and I don't need it, I'm mixing a 50/50 ratio to be safe".
The owner tells me that he has been running his car on the fuel mixture for years and has had no problems at all. He then asks me if I want to go pick up some cooking oil at his shop.
Is this method safe to use with out the conversion?????
