What happens if you dont use premium gas?
As a car owner, you’ve likely noticed the different fuel options at the pump: regular, mid-grade, and premium. While premium gas is often more expensive, some vehicles specifically recommend or require it. But what happens if you decide to skip premium gas and opt for regular instead? Let’s dive into the potential consequences and whether it’s worth the risk.
Understanding Premium Gas
Premium gas typically has a higher octane rating than regular gas. Octane ratings measure a fuel’s ability to resist “knocking” or “pinging” during combustion, which occurs when the air-fuel mixture in your engine ignites prematurely. Premium gas is designed for high-performance engines that operate at higher compression ratios, which require more stable fuel to prevent knocking.
What Happens If You Use Regular Gas Instead of Premium?
If your car’s manufacturer recommends premium gas but doesn’t require it, using regular gas may not cause immediate damage. However, if your car requires premium gas, using regular fuel can lead to several issues:
- Engine Knocking: Regular gas may ignite prematurely in high-compression engines, causing knocking. Over time, this can damage engine components.
- Reduced Performance: High-performance engines are tuned to run on premium gas. Using regular gas can lead to reduced horsepower and acceleration.
- Lower Fuel Efficiency: Premium gas burns more efficiently in engines designed for it. Using regular gas may result in lower miles per gallon.
- Potential Long-Term Damage: Persistent knocking and improper combustion can lead to wear and tear on engine components, potentially resulting in costly repairs.
When Can You Use Regular Gas?
Some vehicles only recommend premium gas but don’t require it. In these cases, using regular gas occasionally may not cause significant harm. However, you might notice a slight drop in performance and fuel efficiency. Always check your owner’s manual to understand your car’s specific fuel requirements.
Tips for Choosing the Right Fuel
To ensure your car runs smoothly and efficiently, follow these tips:
- Always refer to your vehicle’s owner’s manual for fuel recommendations.
- If your car requires premium gas, avoid using regular gas to prevent potential damage.
- If premium gas is recommended but not required, you can use regular gas occasionally, but monitor your car’s performance.
- Consider the long-term costs of engine repairs versus the short-term savings of using regular gas.
Conclusion
While skipping premium gas might save you a few dollars at the pump, it could lead to costly repairs and reduced performance if your car requires it.

Frequently Asked Questions
What happens if I put 87 instead of 91?
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.
What happens if I put 91 instead of 87?
Chances are your vehicle would have reduced fuel economy, but no significant problems should occur. Ultimately, you simply should stick with the octane level your car needs as recommended by the manufacturer.
Is it bad to mix regular and premium gas?
There's nothing wrong with mixing premium and regular gas in the same tank. In fact, this is how midgrade gas is formulated at the station. Rather than drawing from a separate storage tank for each octane rating, gas pumps actively mix high-octane fuel with lower-octane fuel to create midgrade gas.

What if I accidentally put 87 instead of 91?
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.
What happens if you accidentally put 87 instead of 91 in a Lexus?
Use of unleaded gasoline with an octane rating lower than what is listed for your model year vehicle could potentially result in engine knocking. If the octane rating used is less than required, damage to the engine may occur and which could void the vehicle warranty.
Will not using premium gas hurt my car?
In today's automobiles, advances in engine technology mean that even if the owner's manual recommends premium gasoline, the car will typically run on regular without issue and won't damage the engine in any way.
What happens if I use regular gas instead of premium gas?
This will most often come into play if substituting regular for premium leads to significant engine knock or pinging that causes damage to the pistons or other engine components. Aside from those complications, you could also experience a decrease in fuel efficiency and overall engine performance.
What happens if I mix 87 and 93 gas?
Mixing 93 and 87 gas doesn't have any ill effects. It simply creates a new formula referred to as “midgrade” that's often available in gas stations. Additionally, the difference between premium and regular gas is that the premium ones are of higher quality.
Do I really need to use 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.
