    Diesel fuel additives

    Hey people, I have a2008 s320 which has done 70000 miles. It is all ok but when I accelerate hard there is a cloud of smoke from the exhaust. Should I use an additive in the fuel to clean the engine. If so which one? Thanks

    Fuel Additives

    Hi all, is it ok to use certain additives on the 2.3 compressor engines, (m111) to clean the injectors and fuel system? At 67000 it may be time, but I don't know how effective they are and if the manufacturers claims are true. Anybody tried these, and is there a recommendation?
