Maintaining proper fuel quality and system cleanliness is essential for vehicle engine longevity and performance. Using the incorrect octane rating can lead to premature ignition if the fuel is too low, or inefficient combustion if the rating is too high. While occasional mixing of different gasoline grades may not cause immediate failure, long-term use can damage valves, spark plugs, and pistons.
For dual-fuel vehicles using both gasoline and Compressed Natural Gas (CNG), stagnant gasoline in the tank can oxidize and age over time. This degradation can lead to residue buildup in injection systems and cause corrosion in metallic components like pumps and injectors due to moisture. Specialized additives, such as those developed by LIQUI MOLY, are designed to stabilize stored fuel and provide anti-corrosive protection to maintain the integrity of the fuel circuit.
