Rislone Oil Treatment is a high-viscosity formula developed for older and higher mileage engines to increase oil film thickness, building a thicker oil cushion and increasing oil pressure in worn engines. Cushions and coats engine parts to reduce friction and wear by preventing metal-to-metal contact between moving parts giving your vehicle longer engine life. Increased oil pressure equals increased power and a quieter running engine. Improved high-performance formula performs better in both hot and cold weather. Works with all gasoline and diesel engines using conventional, high mileage and synthetic oil.

Rislone Engine Treatment is high quality penetrating lubrication oil, combined with protective engine additives and special cleaning agents.  Its multi-grade formula allows the oil to flow freely and provides protection over a broader temperature range.  Sludge and other harmful deposits within engines can alter tolerances, stick rings, cause noisy valves and lifters, and plug oil passages and screens. The unique Rislone formula is designed to penetrate into bearing surfaces, piston rings and ring grooves, where sludge and varnish is likely to form.  These deposits are gradually removed and held in suspension until they are trapped in the filter or removed with the next oil change. Regular use of Rislone Engine Treatment, with oil and filter changes at the proper intervals, will keep such deposits to a minimum. A cleaner engine is a better lubricated engine with less friction and wear.
