What are GDI (or engine purge) services?
GDI (Gasoline Direct Injection) services for your vehicle refer to maintenance procedures designed to clean and optimize the performance of the fuel injection system. GDI engines inject fuel directly into the combustion chamber under high pressure, which can lead to carbon buildup on intake valves, fuel injectors, and other engine components over time.
Common GDI Services:
- Intake Valve & Combustion Chamber Cleaning – Removes carbon deposits that accumulate on the intake valves and combustion chamber, which can reduce engine efficiency and performance.
- Fuel Injector Cleaning – Cleans the injectors to restore proper fuel atomization, improving fuel economy and engine response.
- Throttle Body Cleaning – Ensures smooth airflow by removing buildup that can affect throttle response.
- PCV System Check & Cleaning – Helps prevent excessive oil and carbon buildup in the intake system.
- Oil & Filter Change – Using high-quality synthetic oil to reduce carbon buildup and protect engine components.
Benefits of GDI Services:
- Restores fuel efficiency
- Improves engine performance and throttle response
- Reduces engine knocking and misfires
- Lowers emissions
- Extends the lifespan of engine components
Regular GDI maintenance is essential, especially since GDI engines are prone to carbon buildup, which can cause rough idling, power loss, and reduced fuel efficiency. Many manufacturers recommend a professional cleaning every 15,000.
