LIQUI MOLY Petrol Stabilizer 250ml

LIQUI MOLY Petrol Stabilizer is a specialized additive designed to preserve the quality of petrol (gasoline) and prevent its degradation over time. This stabilizer is particularly useful for vehicles, equipment, and machinery that may not be used frequently, such as classic cars, motorcycles, lawnmowers, or boats.

The main function of LIQUI MOLY Petrol Stabilizer is to inhibit the oxidation and degradation of petrol, which can occur due to exposure to air and moisture over time. When petrol deteriorates, it can lead to starting difficulties, engine roughness, and even damage to fuel system components.

By adding LIQUI MOLY Petrol Stabilizer to the fuel tank before storage or periods of infrequent use, it forms a protective barrier on the petrol’s surface, preventing oxidation and maintaining its quality.

This helps ensure that the fuel remains fresh and ready for use when needed, without causing any harm to the engine or fuel system.

Additionally, LIQUI MOLY Petrol Stabilizer contains corrosion inhibitors to protect metal surfaces within the fuel system from rust and corrosion during storage.

  2. Preserved Engine Performance: Maintaining petrol quality with this stabilizer helps preserve engine performance, preventing issues associated with stale or degraded fuel, such as starting problems and rough idling.
  3. Prevention of Fuel System Damage: The protective barrier formed by the stabilizer prevents fuel system components from corrosion and damage caused by degraded petrol, saving on potential repair costs.
  4. Convenience and Peace of Mind: With LIQUI MOLY Petrol Stabilizer, vehicle owners can store their vehicles or equipment with confidence, knowing that their petrol will remain fresh and ready for use when needed.

How to Use LIQUI MOLY Petrol Stabilizer

  1. Preparation: Before adding the stabilizer, ensure that the petrol tank is nearly full to minimize air exposure.
  2. Measurement: Refer to the manufacturer’s instructions to determine the appropriate dosage of LIQUI MOLY Petrol Stabilizer based on the petrol tank’s capacity.
  3. Pouring: Carefully pour the required amount of stabilizer into the petrol tank.
  4. Mixing: Start the engine or run the vehicle for a few minutes to allow the stabilizer to mix thoroughly with the petrol.
