The oil in my 1.6 TD goes really black quite quickly. I've heard that running a litre of automatic transmission fluid for a couple of hundred miles before an oil change will help give it a good clean out. Anyone done this before?
I have a can of Wynns diesel engine flush ready to use also but wondering whether ATF will do a better job than 10 mins running the Wynns through?
What are your thoughts guys?
Cheers
