Engine cylinder cross-section - Gasoline Direct Injection (GDI)

Illustration of use

Unlike nozzle injection, GDI intake valves are not flushed by fuel from the injectors and are particularly prone to accumulating harmful deposits before problems arise in expensive upper engines.

  • Engine Type. Four-stroke Gasoline Direct Injection (GDI)
  • Example. Modern gasoline car and light truck engines
  • Applicable products. Sea Foam Motor Treatment, Sea Foam Spray
  • Product Number. SF16CN, SS14CN

Maintenance methods and recommendations for gasoline direct injection fuel systems.

  • Sea Foam Motor Treatment products are used in the fuel to clean and lubricate the fuel nozzles, upper cylinders and combustion chambers.
  • Add 1 to 2 cans of Sea Foam Motor Treatment to the fuel tank every 2,000 - 5,000 miles
  • Use Sea Foam Spray to clean and lubricate the throttle, intake ports, intake valves, upper cylinders and combustion chambers.
  • Use a full can of Sea Foam Spray in the throttle intake at least once or twice a year
