Its design ensures a tight fit, resisting vibration and thermal expansion during engine operation. The cap’s construction is resistant to oil and environmental exposure, helping to prevent leaks and evaporation. Easy to remove for routine oil top-offs and oil changes, it plays a vital role in engine maintenance. A well-sealed filler cap protects internal engine components from dirt and moisture, which could cause damage or reduce efficiency.
