For vehicles over 50,000 miles. Reduce existing wear about 20%, quiet the engine, and add years of dependable life - with independent proof it is working.
High-mileage engines run hotter, louder, and looser. ProTecta's High-Mileage Restoration Program rebuilds a protective barrier on worn metal surfaces while the fuel system treatment clears years of deposits — restoring smoother, quieter performance and adding 100,000+ miles of life.
WearCheck lab analysis measures the drop in wear metals in your own oil.
Extreme-pressure fortifiers protect under towing, hauling, and high-stress driving.
Fuel system treatment cleans injectors and recovers fuel economy.
