Can You Mix 87 And 88 Gas?

Yes, you can mix 87 and 88 gas together without any issues or negative consequences. If you are wondering about the compatibility of different octane ratings, mixing 87 and 88 gas is perfectly safe.

When you mix these two types of gasoline, the resulting octane level will be somewhere in between. This means that it will be suitable for use in most vehicles without causing any harm to the engine. However, it is important to note that using a higher octane fuel than recommended by the manufacturer is unnecessary and may not provide any significant benefits in terms of performance or fuel efficiency.

It is always best to follow the guidelines outlined in your vehicle’s owner’s manual regarding the recommended octane level for optimal performance.

Understanding Fuel Octane Ratings

Octane ratings define the gasoline’s ability to resist knocking or pinging noises in an engine. These ratings represent the fuel’s performance under pressure. Gasoline with a higher octane rating can handle higher compression without detonating prematurely. In the market, you will find various octane ratings like 87, 88, 89, and 91, with higher numbers indicating better performance.

Mixing different octane ratings may not cause immediate harm, but it can affect engine performance. It is generally recommended to use the octane rating specified by the manufacturer for optimal engine functioning. Experimenting with different octane ratings could lead to decreased fuel efficiency and potential engine damage over time.

Understanding the importance of octane ratings helps you make informed decisions about fuel choice for your vehicle.

Can You Mix 87 And 88 Gasoline?

Mixing different octane levels of gasoline, such as 87 and 88, can have effects on your vehicle’s performance and efficiency. While it is generally recommended to use the gasoline octane level specified by your car manufacturer, mixing small amounts of different octane levels, in certain circumstances, may not cause significant problems.

However, it is important to consider that higher octane levels are designed for higher performance engines and mixing fuels with varying octane levels may result in reduced engine performance and efficiency. Additionally, mixing different octane levels can increase the risk of engine knock, which can damage the engine over time.

It is always best to consult your vehicle’s owner’s manual or a professional mechanic for guidance on using the appropriate gasoline octane level for your specific vehicle.

Best Practices For Fuel Mixing

Mixing 87 and 88 gas may not be ideal for your vehicle’s engine performance and longevity. It’s important to follow these recommendations for fuel mix ratios to ensure optimal results. First, it’s best to consult your vehicle’s owner’s manual for specific instructions.

Secondly, consider the octane rating. As a general rule, it’s best to mix gases with similar octane ratings. Next, calculate the desired ratio of each gas based on their respective octane levels. It’s crucial to measure the quantities accurately to achieve the desired mix.

Additionally, ensure that the gas containers are clean before pouring them into your vehicle’s fuel tank. Finally, try to avoid frequently mixing different gas types as it can lead to variations in engine performance. By following these guidelines, you can safely mix 87 and 88 gas while maintaining your vehicle’s optimal performance and longevity.

Frequently Asked Questions For Can You Mix 87 And 88 Gas?

What Happens If You Put 88 Instead Of 87?

Using 88 instead of 87 can cause engine knocking and may result in decreased performance and fuel efficiency.

Is 88 And 87 Gas The Same?

No, 88 and 87 gas are not the same. They have different octane ratings.

Can You Mix Unleaded 88 And Regular Unleaded?

No, unleaded 88 and regular unleaded should not be mixed as they have different octane ratings.

What Happens If I Accidentally Put 88 Gas In My Car?

Putting 88 gas in your car by accident won’t cause significant harm or damage.


It is not recommended to mix 87 and 88 gas in your vehicle due to potential engine damage and reduced performance. The octane rating of gasoline represents its ability to resist engine knocking, which can cause internal damage. Mixing different octane levels can lead to an inconsistent burn rate and impact overall engine efficiency.

It’s best to stick to the manufacturer’s recommended octane level for your vehicle to ensure optimal performance. By using the correct gasoline, you can maintain fuel efficiency, prevent unnecessary repairs, and prolong the life of your engine. If you’re unsure about the right octane level or have any concerns, consult your vehicle’s owner manual or contact a trusted mechanic.

Remember, it’s important to provide your engine with the right fuel to keep it running smoothly for years to come.
