My Focus looks identical (no sludge etc) running Motomaster Supreme conventional oil for 5k miles OCI;s.
My engine is very clean. Any discoloration is the amber colored oil clinging to the head that wasn't wiped off. My OCI was 10K(miles). Notice my pics from the Fusion on page 2. Also this car has a 70% town run.
I concur, it is very clean.
I'm just saying that my engine on conventional with regular OCI's is similar in appearance.
I just I thought it would be cleaner with M1.
I'm not sure how much cleaner than clean my engine could be. In your view, where is this cyl head need cleaning?
