Performance Engine Oil Treatment

This is the product that made Rislone a legend.

A cleaner engine is a better-lubricated engine with less friction and wear. This formula contains 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. The unique Rislone formula is designed to penetrate into valve seats, bearing surfaces, piston rings and ring grooves, where sludge and varnish is likely to form. These deposits are gradually removed with the next oil change. There’s a reason it’s the #1 product chosen by enthusiasts and daily drivers alike.
