Piston decarbonizing

I pull one plug from each cylinder, add 15 mls of Seafoam into each cylinder, let it sit overnight, and then run the engine until the white smoke is gone, then let the engine cool. I then remove the exhaust and examine the piston, cylinder walls, and rings. The result is a clean engine that still has factory spec compression after 17 years and 800 hours of use. I’ve never opened the engine for service or decarboning.  Do what you want, but this process works for me. This routine is part of my annual maintenance in conjunction with my annual condition inspection.

Ed, thank you very much.What is mls in "15 mls"? Is it milliliters ?

Milliliter.....= 1/1000 of a litre

15 mls or 15 ml in "System International units".....the "s" is not required in multiples.

is a measurement of volume used by all countries of the world except two ....Liberia and somewhere else...

15 ml is the same as

it is 0.063 cups....4.0 drams...3.04 teaspoons and about 3.2 of my navels !! and a pinch more than a smidgen...

Glenn, you are such a savior?
