Description
LIQUI MOLY Engine Valve Clean – 150mL | GDI & EFI Engine Cleaner
Restore power and improve fuel economy with LIQUI MOLY Engine Valve Clean. This 150mL fuel additive effectively removes carbon deposits from intake valves, preventing performance loss and rough idling in GDI and EFI engines.
LIQUI MOLY Engine Valve Clean is a highly effective, specialized fuel additive designed to tackle a common problem in modern engines: carbon deposits on intake valves. Formulated specifically for both Gasoline Direct Injection (GDI) and port fuel injection (EFI) systems, this 150mL solution cleans and protects your engine from the inside out. Over time, GDI engines, which spray fuel directly into the combustion chamber, are particularly susceptible to a buildup of hard, crusty deposits on the back of intake valves, as the valves are not regularly washed with fuel. This leads to a host of performance issues, including reduced power, poor acceleration, increased fuel consumption, and rough idling. LIQUI MOLY Engine Valve Clean’s advanced cleaning agents are delivered through the fuel system, where they work to dissolve and remove these stubborn deposits. Regular use helps to restore proper airflow, optimize combustion, and maintain your engine’s original performance characteristics. This product is easy to use—simply add the contents of the 150mL bottle to your vehicle’s fuel tank. It is safe for all gasoline engines and catalytic converters.
Best Uses
- Routine Maintenance: Use every 3,000-5,000 miles to prevent the buildup of carbon deposits on intake valves.
- Performance Restoration: Ideal for vehicles experiencing symptoms of carbon buildup, such as rough idling, hesitation, or a decrease in power and fuel economy.
- Preventive Care for GDI Engines: Essential for vehicles with Gasoline Direct Injection engines to mitigate the risk of intake valve coking, a known issue with this engine design.
- Pre-Emission Test Preparation: Using the product before an emission test can help improve combustion and potentially lower harmful exhaust emissions.
- For All Gasoline Engines: Suitable for use in both GDI and traditional port-injected (EFI) gasoline engines to keep the fuel system and valves clean.
Key Features
- Specialized GDI and EFI Formula: Specifically engineered to address carbon deposit buildup in both modern Gasoline Direct Injection and traditional Electronic Fuel Injection engines.
- Highly Concentrated Cleaning Agents: Contains powerful detergents that effectively dissolve and remove stubborn carbon deposits from intake valves and the combustion chamber.
- Fuel-Based Delivery System: The additive is simply poured into the fuel tank, allowing it to be distributed throughout the fuel system and onto the intake valves during engine operation.
- 150mL Single-Use Bottle: Perfectly sized for a single application, making it convenient and easy to use with a standard tank of fuel.
- Safe for All Components: The formula is designed to be harmless to sensitive engine components, including catalytic converters, oxygen sensors, and fuel system seals.
Key Benefits
- Restores Lost Engine Performance: Cleans intake valves to restore proper airflow, leading to improved throttle response, acceleration, and overall engine power.
- Improves Fuel Economy: By optimizing combustion and restoring ideal fuel-air mixture ratios, the product helps reduce fuel consumption and save money at the pump.
- Reduces Rough Idling and Hesitation: Eliminates the rough and inconsistent idle caused by poor airflow and uneven combustion due to valve deposits, resulting in a smoother running engine.
- Extends Engine Life: Regular cleaning prevents the harmful effects of carbon buildup, such as reduced heat transfer and increased wear, helping to prolong the life of your engine.
- Maintains Engine Cleanliness: Prevents the formation of new deposits, keeping the intake system and combustion chamber clean for consistent, long-term performance.
