What happens if I put regular gas in a premium car?
Putting regular gasoline in a vehicle designed to run on premium fuel can have several negative consequences. While it may work in the short term, it is generally not recommended and can lead to decreased performance, reduced fuel efficiency, and potential long-term damage to the engine.
Understanding the Difference Between Regular and Premium Gasoline
The main difference between regular and premium gasoline is the octane rating. Octane is a measure of a fuel's resistance to premature ignition, also known as "knocking" or "pinging." Premium gasoline typically has a higher octane rating, usually 91 or 93, compared to regular gasoline, which is usually 87 or 88. Engines designed for premium fuel require a higher octane to prevent knocking and ensure optimal performance.
Potential Consequences of Using Regular Gas in a Premium Car
When you put regular gasoline in a vehicle designed for premium, several things can happen:
- Decreased Performance: The lower octane rating of regular gas can cause the engine to knock or ping, leading to a loss of power and acceleration.
- Reduced Fuel Efficiency: The engine may not be able to operate at its optimal efficiency, resulting in decreased fuel economy.
- Engine Damage: Over time, the use of regular gas in a premium car can cause damage to the engine, including increased wear on the pistons, cylinders, and other components. This can lead to costly repairs.
It's important to note that the severity of these consequences can vary depending on the specific vehicle, the frequency of use, and the driving conditions. Some engines may be more tolerant of regular gas than others, but it's generally not recommended to use a lower octane fuel than what is specified by the manufacturer.
Recommendations for Fueling a Premium Car
The best practice is to always use the recommended fuel grade for your vehicle, which is typically premium gasoline. Consult your owner's manual or the fuel information label on the inside of your fuel door to determine the appropriate octane rating for your car. While using regular gas in a premium car may work in the short term, it's not worth the potential risks to your engine and overall vehicle performance.
Can putting regular gas in a premium car mess it up?
Using regular gas in a premium car may lead to engine knocking, causing significant engine damage over time. The cost of repairing such damage can be much higher than the savings from using regular gas. In conclusion, consider your engine's long-term health when choosing between premium and regular gas.
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.
Will regular gas hurt a car that takes premium?
If you use regular fuel in a premium engine, the fuel will ignite prematurely in the cylinder (knocking), which will cause loss of power and damage to the engine. There are some engines which are designed to run best with premium fuel and have knock sensors to detect premature ignition.
What happens if you accidentally mix premium and regular gas?
Luckily, even if you do mix octane levels, your car will be okay. Mixing two grades of gasoline will just average the two octane levels.
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.
Is it bad to mix premium and regular 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.
Is it bad to switch back and forth between regular and premium gas?
Nowadays, engines are more adaptable to the variety. Is it bad to mix premium and regular gas? Well, not necessarily. If your car requires premium to run smoothly, but you aren't able to find a station with premium gasoline, it won't hurt to top off with regular gasoline.
What happens if I put regular gas instead of premium one time?
However, remember this: when a premium fuel engine runs on regular fuel, there's a risk of combustion of the fuel mix before the spark plug even lights up. This causes a phenomenon called knocking, which is likely to damage the engine. Although Mazda recommends using premium fuel, they don't require it.

Steps to Take If You've Misfueled
Call for Help and Tow the Car: Contact a professional mechanic or auto repair service such as Babcock Auto Care. Drain the Fuel: A professional will need to drain the incorrect fuel from the tank and flush the system.
