Meet the Gunk GDI Gasoline and Diesel Fuel System Cleaner, 11 oz—a purpose-built solution from a trusted brand designed for modern engines that demand precise, clean fuel delivery. This GDI-focused formula targets deposits across both gasoline and diesel fuel systems, helping restore peak performance and efficiency.
-
GDI-targeted cleaning action: specifically formulated to address deposits that form in gasoline direct injection and high-pressure diesel systems, restoring spray patterns and fuel flow for smoother operation.
-
Power, response, and smoothness: removes gum, varnish, and carbon buildup to revitalize idle quality, acceleration, and consistent power across the RPM range.
-
Fuel economy and emissions support: cleaner injectors and rails promote more complete combustion, contributing to better efficiency and reduced emissions over time.
-
Versatility for gas and diesel: suitable for use in vehicles with both gasoline and diesel engines, making it a practical choice for households or fleets with multiple vehicles.
-
Convenient, ready-to-use format: packaged in an 11 oz can for easy storage and one-step administration—pour into a nearly empty tank, fill, and drive.
How to use: Pour the entire 11 oz can into a nearly empty fuel tank, then fill with gasoline or diesel and drive normally. As you operate the vehicle, the cleaner circulates through the fuel system, gradually dissolving deposits and delivering a smoother, more responsive drive.
