If your engine runs fine on regular, filling it with premium is unlikely to boost acceleration or fuel economy by more than insignificant amounts. They perform best when fed premium fuel. But if the vehicle manufacturer says your engine needs only 87-octane regular, that is what you should use.
Can You Mix Regular and Premium Gas at the Pump? You can mix regular and premium gas to get a mid-grade octane. In fact, this is what most pump stations do to get a mid-grade-level octane gas. However, mixing premium and regular in a premium car will reduce efficiency and cause it to lose its power.
What happens if you put 87 gas in a car that requires 93?
If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don’t worry. You’re actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.
Which cars require premium gas?
15 ‘Regular’ Cars That Take Premium Fuel
- Buick Envision (with 2.0L turbo)
- Buick Regal (all models)
- Buick Regal TourX (all models)
- Chevrolet Equinox (with 2.0-L turbo)
- Chevrolet Malibu (with 2.0-L turbo)
- Fiat 500L (all models)
- GMC Terrain (with 2.0-L turbo)
- Honda Civic (with 1.5-L turbo)
Is it bad to mix gas from different stations?
Gas stations use different additives in most cases, but there is nothing wrong with mixing stations, or even octane ratings. If you mix 93 and 87 you get 90, mix 89 and 93 you get 91.
With a high level of octane, the chances of engine combustion decrease at any time other than when most likely it has to. Know what happens when you put premium gas in a regular gas car.
What’s the difference between unleaded regular and premium gas?
Before breaking down the difference between gasoline brands, knowing the difference between unleaded regular and premium is the first, most important step. To explain this, a bit of combustion knowledge and chemistry is required. Every vehicle runs through the process of combustion.
Can you save money by not using premium gas?
There’s no guarantee that all of the overachieving engines will benefit from higher octane as the Cruze did in our 2011 test. You can try this yourself to see if you can save money by using premium fuel. Remember, this only applies to a car for which premium fuel is recommended but not required.
If you have a performance car, such as a Corvette, Porsche, or really anything designed specifically for performance, there is a good chance premium is better for your car. Otherwise, the engine isn’t able to take advantage of the superior octane, so it does nothing but cost you more per fill-up.
