Max-Restore contains a high dose of polyether amine (PEA) & proprietary detergents that quickly clean stubborn, long-term deposits, often found in high mileage engines, that clog injectors and provides a protective barrier to keep new deposits from forming.
This optimizes the injector spray pattern and better atomizes fuel as it enters the combustion chamber resulting in enhanced power and performance, reduced emissions, smoother idle, and quicker / easier starts. It also utilizes friction modifier to reduce wear in the upper cylinder to help extend engine life and improve fuel economy.
