This is it – a high-mileage version of what made Rislone famous. The cleaner you keep your car’s lubrication system, the better it runs. Our famous, award-winning Rislone Engine Treatment does just that. This product contains high quality penetrating oil, combined with protective engine additives and special cleaning agents. Its multi-grade formula allows oil to flow freely and provides protection over a broader temperature range. The unique Rislone formula is designed to penetrate into valve seats, bearing surfaces, and piston rings, where sludge and varnish are likely to form. These deposits are removed with the next oil change.
