Fast Motor Flush
Quickly removes sludge, varnish and soft carbon from the crankcase.
Fast acting solvents remove the buildup of sludge and varnish in the upper cylinder areas, oil lines, pump screen, and piston rings which contribute to hydraulic lifter nois, oil consumption, overheating, engine wear, and poor performance.
Add Fast Motor Flush to the crankcase just before scheduled oil change and run the engine for 10 or 15 minutes to loosen varnish and sludge, then while the engine is warm change oil and filter and fill with fresh oil to the manufacturers specifications.
