Introduction

Are you one of those car owners who often mix different grades of gasoline to save money? Well, it\’s not uncommon to have this kind of doubt, especially when you\’re running low on fuel and have no other option. But, is it safe to mix 87 and 88 gas in your car? Let\’s find out.

What is Gasoline Octane Rating?

Gasoline octane rating measures a fuel\’s ability to resist engine knocking or detonation. It refers to the percentage of octane in the gasoline blend. The higher the octane number, the more resistant fuel is to knocking. In general, premium gasoline has an octane rating of 91 or above, while regular gasoline has an octane rating of 87.

Why Mix 87 and 88 Gas in Your Car?

Mixing 87 and 88 gas in your car is not recommended by automakers or fuel companies. However, some car owners do it to save a few bucks at the pump. They believe that mixing two different grades of gasoline will result in a fuel with a rating between 87 and 88.

Is It Safe to Mix 87 and 88 Gas in Your Car?

Mixing 87 and 88 gas in your car is not recommended as it can cause engine damage. Engines are designed to run on a specific octane rating, and mixing different grades can lead to engine knocking, reduced fuel efficiency, and other problems.

What Happens When You Mix 87 and 88 Gas in Your Car?

When you mix 87 and 88 gas in your car, the result is a fuel with an octane rating between 87 and 88. However, this rating is not stable, and the fuel\’s octane rating can vary depending on the amount of each gasoline used. The engine control module (ECM) can detect this and adjust the engine\’s timing and other parameters, but it can only do so much.

What Are the Risks of Mixing 87 and 88 Gas in Your Car?

Mixing 87 and 88 gas in your car can cause engine knocking, which occurs when the air and fuel mixture ignites prematurely. This can lead to engine damage, reduced fuel efficiency, and increased emissions. In severe cases, engine knocking can cause permanent damage to the engine and may require expensive repairs.

Can You Mix 87 and 88 Gas in an Emergency?

In an emergency situation, it\’s better to use a lower-grade gasoline than no gasoline at all. However, using a higher-grade gasoline than recommended can cause engine damage. If you have no other option, you can mix 87 and 88 gas in your car, but only in small amounts and for a short distance.

What Should You Do If You Accidentally Mix 87 and 88 Gas in Your Car?

If you accidentally mix 87 and 88 gas in your car, it\’s best to drain the fuel tank and refill it with the recommended grade of gasoline. Continuing to drive with a mixed fuel can cause engine damage and other problems.

Conclusion

Mixing 87 and 88 gas in your car is not recommended as it can cause engine damage and other problems. If you\’re running low on fuel, it\’s better to use a lower-grade gasoline than no gasoline at all. Remember to always use the recommended grade of gasoline for your car to ensure optimal performance and avoid costly repairs.
