No. All modern high-detergent oils contain a number of additives, but not one is designed to keep oil clean. Additives are used to keep dirt dispersed in the oil so it won’t settle, but it will still circulate through your car’s lubrication system. Any qualified mechanic will tell you that the thin film of oil between closely fitted moving parts is the most important factor in preventing engine wear and reducing friction. Any dirt present in this thin film can cause wear on your engine.

Race drivers, without exception, drain the oil from their crankcase after every race. They know what even the slightest amount of dirt can do to an expensive engine.

Oil performs four vital functions in your car’s engine: it cools, cleans, seals, and lubricates. Only clean oil can properly perform these four vital functions. Automotive and lubrication authorities agree that clean oil performs these functions better than dirty oil.
