When should I use premium gas? Recommended: When your owner’s manual (or the inside of the gas door) recommends premium you can still run your car on a lower grade fuel. For cars that merely recommend it, premium gasoline may very slightly improve performance (increased horsepower) and fuel economy, according to a November 2017 study from AAA.
Does putting premium gas make a difference? Raising the octane rating (also known as the anti-knock index) doesn’t change the energy content of a gallon of gasoline.
A higher octane rating indicates greater resistance to knock, the early combustion of the fuel-air mixture that causes cylinder pressure to spike.
Is there any benefit to using premium gas? If your car doesn’t require premium, fill up with regular.
Is it OK to put premium gas in a regular car? Premium gas 90-93 is completely okay to put in a standard vehicle.
Car experts say there is no risk of damage to a standard car using premium fuel.
When should I use premium gas? – Related Questions
When should you use high octane fuel?
Higher octane allows engines to have higher compression ratios (for a more energetic explosion), more advanced ignition timing or forced-air induction like turbochargers or superchargers.
They perform best when fed premium fuel.
What happens if you put 93 instead of 87?
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.
What happens if you accidentally put regular gas instead of premium?
The ‘science’ behind it.
Premium gas has a higher-octane level than regular gas; or, in other words, a higher resistance to detonation.
As various pressures rise inside of the cylinder of the engine, this will also result in a temperature rise, and the gasoline will sometimes detonate, or, “explode” in the cylinder.

Does premium gas clean engine?
Nope. Regular, plus, and premium gas all come with detergents to mitigate against carbon deposits in your engine. Plus and premium don’t come with special powers for cleaning out the engine. If you’re interested in cleaning out your engine, you’re better off taking it in for service.
Does premium gas last longer?
Sadly, there’s nothing in premium gasoline that would make it last longer than other fuels from the pump.
Since the distinguishing feature is the higher-octane levels, the only real benefit you gain is lowering the chance of engine knocking, which isn’t much of a threat on most modern fuel systems.

What happens to a car if you put the wrong gas?
What to do: Gas engines can’t combust diesel, so your car may not start; if it does, it will probably smoke. While engine damage is unlikely, you will need to get the tank drained, a service that may range from $500 to $1000, and pay for the cost of a tow.
Does higher octane fuel give better mpg?
The benefits of high-octane unleaded petrol outweigh the extra cost of the fuel, expert tests have concluded.
The car running 99 Octane averaged 25mpg during the tests, while the lower-octane fuelled car returned 22mpg.
That’s an overall improvement of 14 per cent.
What octane is jet fuel?
Modern aviation unleaded fuels are currently being developed, such as 82UL in the United States. This is an 82 Octane Lean Mixture rating fuel and is approved for use in modern non turbo Avco Lycomings engines amongst others.
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.
Do you get more horsepower with premium gas?
Non high performance engines do not gain horsepower from the use of premium gasoline. Premium gasoline cleans the fuel system to a degree but does not add horsepower.
What happens if you mix 89 and 93 gas?
No, you will not damage your engine by mixing different octane fuel. It is still fuel. Say you mixed 2 gallons of 87 octane with 2 gallons of 89 octane and 2 gallons of 93 octane.

What happens if you mix 87 and 89 gas?
Yes.
You will not harm your car by mixing different octane grades of the same gasoline providing your car’s engine is designed to run on less than 89 octane fuel and you are not using E85 in a non-E85 compatible engine.
50% 87 octane gas mixed with 50% 89 octane gas makes 88 octane gas.
