As stated on here somewhere, the injection systems on diesel Mercedes will pass a gallstone.so a few of us will be able to hang on with waste oils and crude oil and such. I suppose in the future diesel and gasoline will become niche markets that will price most out of being able to use them for daily transportation. I drove a 12.5 to 1 compression ratio big block Mopar as a daily driver for many years. Racing fuel finally got so expensive I couldn't justify it anymore. In the US we don't pass laws, they just price you out of forbidden behavior.lol
