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 & 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.
