BG Quick Clean for Engines safely and effectively removes deposits from engine components. Vehicle engines have close tolerances, precision construction, and anti-pollution devices. While these features make engines more efficient than ever, they also make engines extremely sensitive to built up varnish, gums and debris. These deposits cripple engine performance. BG Quick Clean for Engines restores power and performance to your engine by rapidly and effectively removing accumulated deposits that form in the piston ring belt, hydraulic lifters, rocker arms and other critical engine parts. As part of an oil change, BG Quick Clean is added to the oil, then run engine for 10-15 minutes. When the old oil is drained, contaminants are quickly flushed away.
