Genuine Subaru Fuel Additive

Subaru Fuel Additive has been developed to complement Subaru Upper Engine Cleaner SA459 between service schedules and is recommended every 15,000 miles. Formulated to reduce combustion chamber deposits, as well as cleaning thus helping the entire fuel system & maintain the vehicle at peak performance between services.

Fuel Additive Features & Benefits

The deposit removal pattern of Subaru Fuel additive starts at the intake valve, progressing around the combustion chamber to the spark plug and finally past the spark plug and across the exhaust valve. Subaru fuel additive is a dispersant and not a solvent. Intake system deposits are dramatically reduced. Fuel injector deposits are reduced in one treatment.
