Premium Gas Makes Check Engine Light Go Off

If your car’s check engine light is on, and you’re wondering if premium gas might be the culprit, you’re not alone. Many drivers have experienced this problem and have turned to premium gas as a potential solution. So, does premium gas really make the check engine light go off?

The answer is maybe. If your car is designed to run on premium gas, then using a lower-grade gas can cause the check engine light to come on. This is because the lower grade gas doesn’t contain the same amount of cleaning agents as premium gas, and over time, this can cause build-up and deposits in the engine. If you switch back to premium gas, the light should go off.

However, for a car that is designed to run on regular gas, using premium gas won’t have any effect on the check engine light. In this case, the light is likely being caused by something else, such as a loose gas cap or a faulty sensor.

If you’re not sure what grade of gas your car requires, consult your owner’s manual or ask a mechanic. In the meantime, if your check engine light is on and you’re using premium gas, it’s worth a try switching back to regular gas to see if the light goes off.

Can premium gas help fix engine problems?

There’s no denying that premium gas is a high-quality fuel. But just because it’s a high-quality fuel doesn’t mean that it can magically fix engine problems.

If your check engine light is on because of a problem with your ignition system, for example, premium gas isn’t going to do anything to fix the issue. The same is true if your check engine light is on because of a problem with your engine’s sensors or computer system.

In short, premium gas can’t fix every problem that might cause your check engine light to come on.
