A check engine light could be telling you about a bad fuel cap


A malfunctioning fuel cap can lead to significant issues, including triggering your vehicle’s check engine light. While you can’t control the fluctuating fuel prices, you can prevent fuel loss due to evaporation by ensuring your gas cap is in good condition and seals correctly.

Recent data from Carcare.org reveals that nearly 20% of vehicles on the road require a replacement fuel cap. This oversight results in approximately 150 million gallons of fuel evaporating into the atmosphere annually. To put it into perspective, a faulty fuel cap can cause the wastage of up to 30 gallons of fuel per year, translating to a loss of over $100 for vehicle owners.

If your gas cap starts emitting fuel vapors, it’s a clear sign that the seal is deteriorating. This deterioration prevents the cap from maintaining the necessary pressure inside the fuel tank, potentially leading to the activation of your vehicle’s check engine light after refueling.

It’s worth noting that fuel caps can develop leaks irrespective of their age. However, vehicles older than three years or those operating in hot and dry climates are more susceptible to such issues.

To address this problem, MotoRad offers a comprehensive range of both locking and non-locking fuel caps suitable for nearly all vehicle makes and models. Investing in a new MotoRad fuel cap not only prevents fuel evaporation but also ensures compliance with all federal standards for fuel cap performance. Replace your faulty fuel cap today to save fuel, reduce emissions, and avoid triggering your vehicle’s check engine light.
