Rislone Hy-per Lube Zinc ZDDP Supplement is a petroleum oil performance booster containing ZDDP (zinc dialkyldithiophosphate) Zinc and Phosphorous EP (extreme pressure) additives along with mixed esters to help protect internal engine components including pistons, flat tappet camshafts, lifters, pushrod tips and the rest of the valve train. High performance formula stabilizes the motor oil to insure against viscosity and thermal breakdown. Reduces friction and wear, especially at start-up, helping to eliminate dry starts. Less friction means less wear and a cooler running, longer lasting engine. Clinging action keeps bearings and other internal engine parts lubricated where normal oil fails.

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.
