As vehicle mileage increases, engine performance suffers from gasoline-generated deposits that form on the fuel injectors, intake valves and combustion chamber. Additives are required to control deposit formation, but today’s fuels lack sufficient treatments of high-quality additives. That is why so many vehicles experience lost fuel economy, lost power and poor throttle response, failed emission tests, poor drivability (surging, hesitation, stalling, rough idle), engine knocking (pinging) and rap and difficult starts.
AMSOIL P.i.® offers a potent solution to the problems posed by dirty gas. It is a concentrated detergent, which makes it highly effective in cleaning combustion chamber deposits, intake valve deposits, port fuel injector deposits and gasoline direct injector deposits. AMSOIL P.i. helps maintain peak engine efficiency, fuel economy, power and drivability in newer low-mileage engines. In engines with accumulated deposits, testing shows AMSOIL P.i. provided the following clean-up benefits after only one tank of gasoline:
• Improved fuel mileage an average of 2.3% and up to 5.7%
