The quality of modern engine oils are very good. There are products like Sea Foam to clean sludge and carbon build-up. In the old days (1950's & 1960's) I used kerosine to clean the lower end and water to clean the carbon but todays engines are built of different materials. I some times use Lucas fuel treatment in the gasoline to help keep the upper end clean.
Have a good one.. Don S..
