Doc’s Auto Parts Gas System Treatment: Doc’s Auto Parts Gas System Treatment was built with high-strength P.E.A. (Polyether-amines) and engineered to remove tough carbon deposits throughout modern gasoline engines. This advanced formula survives extreme combustion temperatures, allowing it to clean areas ordinary detergents can’t. It cleans the entire system from the tank to the injectors to the combustion chamber—freeing stuck deposits, restoring throttle response, smoothing idle, and helping engines run the way they were meant to. Product Details: Heat-Stable P.E.A. That Actually Survives Combustion – Ordinary detergents break down before they reach your injectors. Doc's uses high-strength Polyether-amine (PEA) built to hold up under combustion heat, so it keeps working all the way to the intake valves and combustion chamber — not just the fuel line. Removes Fuel System Deposits– One 12 oz bottle breaks down stubborn carbon and varnish buildup in injectors, intake valves, and the combustion chamber — the deposits behind rough idle, hesitation, and that sluggish feeling off the line. Restores Lost Engine Performance– Regular use restores injector spray patterns, sharpens throttle response, smooths out rough idle, and helps you get more miles out of every tank. Works In Every Gas Engine You Own – Compatible with GDI, PFI, turbocharged, and naturally aspirated engines in cars, trucks, SUVs, and performance vehicles. Safe with E15 ethanol blends, and won't harm oxygen sensors, catalytic converters, seals, or gaskets. Maintenance Made Easy, No Guesswork – One 12 oz bottle treats up to 20 gallons. Pour it in every 10,000 miles for routine upkeep, or every 3,000–5,000 miles if you're chasing max performance — backed by a family business that's kept vehicles running for generations.
