What kind of gas should I put in my Chevy?
Choosing the right type of gas for your Chevy is essential for maintaining its performance, fuel efficiency, and longevity. With so many options at the pump, it can be confusing to determine which fuel is best for your vehicle. In this article, we’ll break down the factors you need to consider when fueling your Chevy, so you can make an informed decision every time you visit the gas station.
Understanding Your Chevy’s Fuel Requirements
The type of gas your Chevy requires depends on the specific model and engine type. Most Chevy vehicles are designed to run on regular unleaded gasoline with an octane rating of 87. However, some high-performance models, such as those equipped with turbocharged or supercharged engines, may require premium gasoline with a higher octane rating to prevent engine knocking and ensure optimal performance.
To determine the correct fuel for your Chevy, consult your owner’s manual. The manufacturer provides detailed recommendations based on your vehicle’s engine specifications. Ignoring these guidelines can lead to reduced performance, lower fuel efficiency, and potential engine damage over time.
What Is Octane Rating and Why Does It Matter?
The octane rating of gasoline measures its ability to resist knocking or pinging during combustion. Knocking occurs when the air-fuel mixture in the engine’s cylinders ignites prematurely, which can cause damage to the engine. Here’s a quick breakdown of the common octane ratings:
- Regular (87 Octane): Suitable for most standard Chevy models with naturally aspirated engines.
- Mid-Grade (89 Octane): Sometimes recommended for vehicles that experience mild knocking with regular gas.
- Premium (91-93 Octane): Required for high-performance Chevy models, such as the Corvette or Camaro with advanced engine designs.
Using a higher octane fuel than recommended won’t necessarily improve your vehicle’s performance or fuel economy. Stick to the manufacturer’s guidelines to avoid unnecessary expenses at the pump.
Special Considerations for Flex-Fuel Chevy Models
Some Chevy vehicles are equipped with flex-fuel engines, which can run on either regular gasoline or E85 (a blend of 85% ethanol and 15% gasoline). If your Chevy is flex-fuel compatible, you’ll notice a yellow gas cap or a label indicating E85 compatibility. While E85 is often cheaper than regular gasoline, it has a lower energy content, which can result in reduced fuel economy. Consider your driving habits and budget when deciding whether to use E85.
Tips for Choosing the Right Gas
Here are some practical tips to ensure you’re fueling your Chevy correctly:
- Always refer to your owner’s manual for the manufacturer’s fuel recommendations.
- If your Chevy requires premium gasoline, avoid using regular gas, as it can lead to engine knocking and reduced performance.
- For flex-fuel vehicles, weigh the cost savings of E85 against its lower fuel efficiency.
- Pay attention to your vehicle’s performance. If you notice knocking or reduced power, consider switching to a higher octane fuel.
Conclusion
Choosing the right gas for your Chevy is a simple yet crucial step in maintaining your vehicle’s health and performance. By following the manufacturer’s recommendations and understanding your engine’s needs, you can ensure a smooth and efficient driving experience.

Frequently Asked Questions
Which gas is better 87 or 93?
What Is The Difference? Regular gas is rated at 87 octane in most states while higher octane pump gas is rated at 91 to 93. Essentially octane levels are the rate at which fuel combusts, with 87 octane combusting the easiest/soonest and 91 to 93 octane can sustain higher levels of combustion.
What happens if you put 87 in a V8?
If you put lower-octane fuel into your high-octane vehicle, whether by mistake or to save money on gas, you'll probably notice the effects right away: things like poor fuel economy, reduced acceleration, and spark knock, which sounds like a high-pitched pinging or rattling noise.
Should I use 90 or 87 gas?
The higher an octane number, the more stable the fuel. Retail gasoline stations in the United States sell three main grades of gasoline based on the octane level: Regular (the lowest octane fuel–generally 87) Midgrade (the middle range octane fuel–generally 89–90)
What vehicles need premium gas?
As a rule, vehicles with turbocharged engines or high-performance sports engines often rely on premium gas to perform their best. These engines will often be engineered and built with parts to respond more efficiently with higher-grade fuel.
Is it better to use regular or premium gas?
Should I use regular or premium gas? You should use the type of fuel the vehicle's manufacturer recommends. A vehicle that runs on regular gas will not run any better on premium fuel. Using premium gas in a vehicle designed for premium gas will help the car perform better and avoid damaging the engine with regular gas.
Should I put 87 or 89 gas in my car?
Higher octane just reduces the risk of detonation in a high comp or forced induction engine. Higher octane fuels burn less quickly and require more energy to activate or burn. So 87 is just fine and 89 or higher is a waste without tuning the engine to run on 91 or higher.
What if I accidentally put 87 instead of 89?
It shouldn't cause your vehicle any harm. The ECM (Engine Control Module) will compensate for the lower octane fuel. You might notice a drop in engine performance and possibly lower fuel economy; but nothing detrimental.
What Chevy is best on gas?
The most fuel-efficient Chevy model is the 2022 Chevy Spark, which offers up to 38 highway mpg. Trailing just behind is the 2022 Malibu, which offers up to 36 highway mpg.
What happens if you put 93 gas in an 87 car?
Engine computers can usually adjust their timing to account for the increased octane levels, so if you put premium gas in a regular car, you probably won't notice anything. However, some engines are not designed to burn higher-octane fuel, and you may see a reduction in performance and fuel economy.
What gas does Chevy recommend?
Engine Suitability: Engines with low compression ratios can often run perfectly fine on regular unleaded, as it burns quicker than premium. If your vehicle has a high compression ratio, premium gas is recommended.
