Features & Benefits

Rislone compression repair with ring seal is concentrated proprietary blend of high-shear premium polymers developed for higher mileage engines that are suffering from decreased or uneven compression. Low compression can be caused by normal engine wear and decreased sealing between the piston rings and cylinder walls. The non-dispersant olefin copolymers fill scratches and grooves in cylinder walls to increase and stabilize compression in all cylinders. Compression repair renews worn engines, rebuilds compression, restores lost power and repairs engine blow-by. In addition, compression repair helps vehicles pass emission tests.

  • Product works by freeing sticky rings and filling gaps and scratches in cylinder walls, eliminating blow-by and compression loss while also reducing friction and wear. blow-by is usually caused by gaps in internal engine parts resulting from excess wear.
  • Rislone compression repair with ring seal does not contain any harmful lead or other metals that could damage the inside of your engine or be burned and contaminate emissions components and the environment. it meets the most severe passenger car and truck requirements.
  • The viscosity improver is designed specifically to provide an optimum balance of shear stability and thickening efficiency required in old and modern engines.
  • Some signs of decreased compression include loss of power, poor fuel mileage, oil consumption, blue smoke from exhaust, plug fouling and engine noise or vibration.
