Compression Repair

The Compression Repair with Ring Seal petroleum additive was developed for high-mileage engines hampered by decreased or uneven compression caused by normal engine wear and decreased sealing between piston rings and cylinder walls. The additive is formulated to fill scratches and grooves in cylinder walls and free stuck rings. It’s compatible with four-stroke gasoline and diesel engines.
