Nulon Engine Oil Flush (EOF) is formulated to dissolve and dislodge harmful sludge, dirt, varnish and other contaminants that accumulate within an engine's lubrication system between oil change intervals.

Although modern engines are cleaner from an environmental aspect, all the pollutants of engine combustion previously released into the atmosphere are now recirculated within the engine. Consequently, lubricating oils have a much more difficult task in cleaning and suspending all these additional contaminants.

When added to the crankcase oil prior to each oil and filter change, Nulon Engine Oil Flush greatly assists in ridding the engine of potentially damaging contaminants. Nulon Engine Oil Flush also helps to free sticky valves and hydraulic lifters. Thermal efficiency of the engine is also improved by ridding the engine of insulating sludge build-up. EOF provides a cleaner environment for fresh oil to operate, so the detergent dispersant and antioxidant additives in the new oil are not depleted as quickly.
