Can I use 88 gas instead of 87? In most cases, you can use 88-octane gas instead of 87-octane gas without causing harm to your vehicle. However, it might not provide any significant benefits unless your engine specifically requires or is optimized for higher-octane fuel.
Here I will discuss the details of 87 and 88 gas. So, let’s start.

Can I Use 88 Gas Instead Of 87? Is 88 Gas The Same As 87 Gas?
You can use 88-octane gas instead of 87-octane gas in most vehicles without causing harm. However, they’re not the same in terms of their octane ratings.
88 octane gas has a slightly higher octane rating than 87 octane gas. The difference in octane levels means 88 gas offers a bit more resistance to engine knocking under compression than 87 gas.
Though they serve the same basic purpose as fuel for combustion engines, the difference lies in their ability to resist premature combustion or knocking. Engines designed for regular 87-octane gas generally operate perfectly fine using 88-octane gas. However, they might not experience noticeable improvements in performance or efficiency.
Why Do We Need 88 Gas?
88 octane gas is needed for certain high-performance or turbocharged engines with higher compression ratios. This fuel prevents engine knocking. It optimizes performance by resisting premature ignition in these specialized engines. Some vehicles and engines are designed to take advantage of higher-octane fuel for better power delivery and efficiency.
Most cars run fine on 87-octane gas. However, specialized engines may benefit from or require 88-octane gas to ensure smooth operation and optimal performance. Always consult your vehicle’s manual for the recommended octane rating.
Why Do We Need 87 Gas?
87 octane gas is widely used because it suits most engines without issues. It’s a standard, cost-effective fuel grade available at most stations. It offers balanced performance for everyday driving. Manufacturers often recommend it for optimal engine operation. Thus, it becomes the preferred choice for the majority of vehicles on the road.
Difference Between 88 Gas And 87 Gas? 88 Gas vs 87 Gas
Let’s see the comparison between 87 and 88 gas.
| Aspect | 87 Octane Gasoline | 88 Octane Gasoline |
| Octane Rating | Standard grade, resistant to engine knocking in most cars | Slightly higher octane, offers slightly more resistance to knocking |
| Engine Performance | Slightly higher octane offers slightly more resistance to knocking | Some high-performance engines might benefit slightly |
| Cost and Availability | Widely available, generally less expensive | Less common, may be slightly more expensive |
| Fuel Efficiency | Typically no significant increase in efficiency | Minor improvements in specific engines |
| Engine Requirements | Suitable for most standard vehicles | Might be recommended for high-performance or specialized engines |
| Common Use | Standard choice for most cars | Less commonly used |
Can I Mix 87 And 88 Gas? 6 Reasons Why You Can’t!
Mixing 87 and 88 octane gas in your vehicle’s tank is generally acceptable and shouldn’t cause immediate harm. The resulting octane level will fall between the two grades. However, it’s not an ideal practice for a few reasons:
1. Consistency
Mixing different octane fuels might affect the engine’s performance consistency. Your engine’s computer is optimized for a specific octane rating, and variations could impact fuel combustion and efficiency.
2. Optimal Performance
Engines tuned for a particular octane may not perform optimally with a mixed-grade fuel. It might cause knocking or reduce power efficiency.
3. Not Recommended
Manufacturers don’t advise mixing different octane fuels. Because it can lead to unpredictable combustion properties and potential engine issues over time.
If you inadvertently mix the two grades, it’s generally safe to use the fuel in your car, especially if it’s a one-time occurrence. However, for consistent and optimal performance, it’s best to refuel with a single, appropriate octane grade recommended for your vehicle.
Advantages Of Using 88 Gas Instead Of 87
Using 88-octane gas instead of 87-octane can offer a few advantages, primarily in certain engine types or driving conditions:
1. Reduced Engine Knock
Higher octane fuels like 88 gas provide better resistance to engine knock in high-performance or turbocharged engines with higher compression ratios. This resistance prevents premature ignition, ensuring smoother engine operation.
2. Optimized Performance
Some high-performance engines are specifically tuned to take advantage of higher octane fuels. Using 88 octane gas in these engines can potentially enhance power delivery and overall performance, especially during demanding driving conditions or aggressive acceleration.
3. Engine Protection
In certain specialized engines, higher octane fuel might offer better protection against deposits or carbon buildup, contributing to cleaner engine operation and potentially extending engine life.
However, it’s important to note that these advantages might not be significant for most vehicles designed to run on 87-octane gas. Using 88-octane gas in a car not engineered for higher-octane fuels might not yield noticeable improvements in performance or efficiency.
Always refer to your vehicle’s manual or manufacturer’s recommendations regarding the appropriate octane rating to ensure optimal engine performance and longevity.

Bottom Line
Using 88 octane gas instead of 87 is generally safe. But it’s not universally beneficial. Higher octane fuels offer advantages in certain engine types. For example, reduced knock in high-performance engines, optimized power delivery, and potential engine protection.
However, these benefits might not apply to all vehicles designed for 87 gas. Mixing 87 and 88 octane gas isn’t recommended due to potential performance inconsistencies. Most cars run well on 87 octane, which is widely available and cost-effective. Always follow your vehicle’s manual for the recommended fuel type to maintain optimal engine performance and efficiency.
