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 & 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 & wear.
No, Rislone Engine Treatment Concentrate is formulated to be left safely in the crankcase for the life of the oil change for maximum performance. It is not an engine flush and does not require draining.
Rislone Engine Treatment gradually dissolves and removes harmful deposits of varnish, sludge and gum from the internal metal parts without plugging oil passages. These deposits form within engines and can alter tolerances, stick valves and rings, cause noisy valves and lifters, and plug oil screens and passages. Regular use of Rislone Engine Treatment, with oil and filter changes at the proper intervals, will keep such deposits to a minimum.
Rislone Engine Treatment Concentrate starts working the minute you install and start driving the vehicle to help remove harmful gum, sludge, and deposits from your engine.
