QMI Oil System Cleaner circulates through the engine, where its concentrated oil based detergent action scours away gums, varnish and carbon deposits. Then suspending agents emulsify dirt and contaminates for safe removal from crankcase at oil drain. Helps reduce oil consumption from restricted or blocked return oil drain channels in the cylinder head. If not addressed, this condition contributes to oil starvation and engine seizure. Helps free sticky lifters and maintains good flow of lubricant throughout the engine. Frees piston ring land deposits, reducing compression loss and blow-by. Extreme pressure agents improve lubrication of critical areas and protect against loss of lubrication during cleaning. Friction modifiers and extreme pressure agents lubricate and protect while cleaning. Helps extend engine life by removing abrasive wear metal and dirt particles, reducing wear on engine working components, seals and o-rings. Used as part of the vehicles regular oil system maintenance program, QMI Oil System Cleaner reduces the accumulation of deposits that can block oil lines and screens to inhibit engine lubrication and cause premature engine failure. “Don’t put clean oil in a dirty engine!”
