To prevent gas from getting into the oil in your engine, ensure that the fuel system and components are in good condition. Regularly check the fuel injectors, carburettor (if applicable), and fuel pressure regulator for leaks or malfunctions, as issues here can cause excessive fuel to enter the engine oil. Make sure the engine’s compression is healthy, as low compression from worn piston rings or valve seals can allow fuel to seep past and mix with the oil. Keep the fuel system clean by using high-quality fuel and maintaining the fuel filter. Also, avoid overfilling the gas tank, which can sometimes result in fuel spillage that enters the crankcase. Regular oil changes and timely engine diagnostics can help detect and fix any fuel-to-oil contamination early, preventing long-term damage to your engine. Lastly, always ensure that the vehicle is not idling for prolonged periods, which can also contribute to this issue.
