Hi all,
the engine oil in my sight glass is very black although I changed it 5k ago. I would like to do an engine flush, are there any known problems doing this on these engines?
Thanks for any replies.
Bob

+1.

The oil does go black very quickly, partly because the oil and filter change does leave some oil in galleries around the engine and also because of the combustion process.
