How fuel and engine additives can improve performance, clean your system, and save you money.
Most drivers think of fuel and oil as the only fluids their engine needs. But additives — used correctly — can clean deposits, improve combustion, and extend the life of your engine and fuel system.
1. Fuel Injector Cleaner
Over time, carbon deposits build up on your fuel injectors, reducing spray efficiency and causing rough idling, hesitation, and increased fuel consumption. A quality fuel injector cleaner — like Molinol Fuel Injector Cleaner — dissolves these deposits and restores proper fuel delivery. Use it every 5,000 to 10,000 km for best results.
2. Fuel Octane Booster
If your engine is designed for higher-octane fuel but you’re using regular, you may notice knocking or reduced performance. Molinol Fuel Octane Booster raises the effective octane rating of your fuel, reducing engine knock, improving combustion efficiency, and helping you get more power and better mileage from every tank.
3. Coolant Stop-Leak
Small leaks in hoses, gaskets, or the radiator can often be sealed without a major repair. A coolant stop-leak additive — like Wepp Coolant Stop-Leak — circulates with the coolant and seals minor cracks and weeping joints from the inside. It’s a quick, low-cost fix for slow leaks, though persistent or heavy leaks still need proper inspection and repair.
4. Engine Ceramic Protection
Ceramic engine treatments add a microscopic protective layer to internal metal surfaces, reducing friction and wear. A product like Wepp Engine Ceramic Protection helps your engine run quieter and cooler, improves protection during cold starts, and can extend the life of moving parts — especially worthwhile for higher-mileage engines.
