Rislone Compression Repair with Ring Seal is a proprietary blend of petroleum additives developed specifically for higher-mileage engines suffering from decreased or uneven compression.
- Fills scratches and grooves in cylinder walls to prevent blow-by gasses and compression from leaking past the rings and fouling the crankcase oil
- Frees sticky rings to increase compression while reducing friction and wear
- Works with all petroleum-based motor oils including conventional, high-mileage and synthetic formulas
- Compatible with any four-stroke gasoline or diesel engine
