Purpose and Specifications
GAT Diesel System Clean & Protect is a fuel system additive designed to keep your diesel engine running cleanly and efficiently. This 300ml bottle treats up to 10 liters of diesel fuel and works automatically during normal engine operation.
The additive removes carbon deposits, soot buildup, and fuel residues from your entire fuel system—from the tank all the way to the combustion chamber. It's especially useful if you use low-sulfur diesel, as it provides extra lubrication to your fuel injection pump and protects against corrosion.
Key Benefits:
- Removes carbon and soot deposits that reduce engine efficiency
- Protects fuel injectors from clogging and wear
- Improves fuel atomization for cleaner combustion
- Reduces fuel consumption and exhaust emissions
- Prevents corrosion in fuel system components
- Works in all diesel engines, including modern common rail and high-pressure direct injection systems
How Much to Use: Add 50ml per 10 liters of diesel fuel. One 300ml bottle treats approximately 60 liters of fuel.
When to Use / Replace?
Add this additive with every fuel tank fill-up for continuous protection. The product works during normal driving—no special procedures needed. For best results, use at least once per year, or more frequently if you drive in stop-and-go traffic or notice reduced fuel economy.
There is no replacement interval for the additive itself; you simply add a fresh dose each time you refuel. The product has a standard shelf life of several years when stored in a cool, dry place.
