broken piston rings combustion carbon deposits cause engine problemsFTC Decarbonizer fuel catalystStuck piston rings are caused by carbon deposits in the ring grooves. Hard carbon, a result of poor fuel combustion, virtually cements the rings into the grooves. In the past, the only way to free up stuck piston rings so they seal properly again, was to overhaul the engine. However, now, by using FTC Decarbonizer in the fuel, a safe, very low cost, and completely effective method of oxidizing (burning off) carbon deposits, including  injector carbon, cylinder glaze, piston ring groove deposits, etc, is the better alternative. Thousands of engines have avoided expensive mechanical overhaul by using this unique fuel catalyst. Find out more here…
