Purpose and Specifications
The LIQUI MOLY 21421 E10 Additive is a premium 150 ml fuel treatment designed specifically for gasoline engines using E10 fuel. It cleans the fuel system, boosts acceleration, and ensures smoother engine running by countering E10's drawbacks like power loss and corrosion. One can treats 35 to 70 liters of fuel, making it perfect for cars, motorcycles, 2-stroke, and 4-stroke engines. Safe for catalytic converters with no organometallic compounds.
- Key Benefits: Restores lost power from E10, protects against water in fuel, prevents injector deposits and corrosion.
- Practical Use: Add to tank before refueling; effects noticeable after one tank in partial-load driving like city trips.
- Shelf Life: Up to 3-5 years unopened in cool, dry storage (5-25°C).
When to Use / Replace?
Use every 5,000 km or monthly with E10 fuel to maintain performance, especially in short-trip driving or older engines prone to ethanol buildup. Replace if fuel smells off or acceleration feels sluggish. Ideal for temps from -20°C to 40°C, stabilizing fuel year-round.
