Is it safe to flush the engine (my franchised dealer does > it to my 9000 every year)? I've had no qualms flushing my 9000 either. Why are you concerned here ? Maybe someone would care to comment on the relative merits of flushing oil vs a flushing additive ? In the case of the first you drain the old oil, refill with flushing oil, run the engine for a while, drain again and then complete the oil change as normal. The additive of course is simply poured in and the engine run for a while before performing the oil change. Instinctively, I reckon the flushing oil must do a more complete job. Graham
