Engine & Oil Products


Cleans piston rings and lifters to restore engine power and performance.

The Problem

As a vehicle is driven, its engine is gradually wearing out the properties of its lubricating oil, using up the chemical additives and eventually, the base oil oxidizes, forming varnish and sludge. Over time, deposits and residue will build up and restrict the free movement of parts; reducing the efficiency of the engine.

The Solution

BARDAHL Ring-Eeze contains powerful detergents that remove varnish and sludge and prevent piston rings and lifters from sticking to restore the free movement of critical engine parts. The formula contains patented chemistry that dissolves deposits and keeps them in suspension to inhibit future formation.  This product also contains anti-wear and friction modifiers that reinforce the OEM additives blended into motor oil to continue the effective lubrication of the rings, cylinders, and valve train. It is safe to use in 4-stroke engines, including various types of motors, generators, and agricultural equipment.
