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) Premium (the highest octane fuel–generally 91–94).
Is 91 octane the same as 87?
Two common octane ratings are 87 and 91. The main difference between 87 and 91 octane gas is just the additive that they add to it. They are still the same unleaded gasoline that will work on your car. An 87 octane gas is more prone to pre-detonation since it ignites at a lower temperature than 91 octane gas.
Is regular gas high octane?
The octane rating on gas is what mostly differentiates regular gas from premium. Regular gas sits at an 87-octane rating and premium gas is 91, or higher. High octane gas helps prevent early fuel ignition which results in engine knocking that can damage your vehicle.
What octane is regular gas in Canada?
Octane ratings for regular, mid-grade and premium Shell fuels across Canada are 87/89/91. In the United States, an 85-octane fuel is available in some markets of higher elevation such as the Rockies and premium ratings for premium can range from 91 to 93, depending upon the market.
What happens if you put 93 gas in a 87 car?
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 use 87 instead of 91?
“Use premium unleaded gasoline with a posted octane rating of 91 or higher. If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. Some manufacturers recommend premium gas but say that regular or mid-grade gas can be used instead.
What happens if I use 89 instead of 87?

Is 91 and 93 gas the same?
Premium gas is usually considered to be any gasoline that has an octane level of 91 or higher. You’ll usually see these listed on pumps as 91 or 93. Sometimes, 93 octane will be listed as “super-premium” or “ultra.” Unleaded gasoline is usually considered to be “regular” when it is 87 octane.
Is Supreme gas a premium?
Regular gas has the lowest octane rating, Premium has a higher octane and Super (or Supreme or Premium Plus) has the highest octane. If you’re putting premium gas into your vehicle thinking that ‘premium’ means better, you could be damaging your engine.
Does 93 octane burn slower?
These octane level numbers (87, 89, 91, etc.) Lower octane gas burns quicker than higher octane, and so require less energy to ignite. However, this also means that lower octanes burn more quickly in high pressure environments, and can have a greater tendency to knock.
What happens if you mix 91 and 93 gas?
Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.
What octane is 91 Aki?

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.
Why do some cars need premium gas?
Simply put, high-octane gasoline can be compressed and heated to a greater degree without self-igniting. That’s why high-performance engines use premium fuel. Since the engine doesn’t make quite as much power with low-octane fuels, this translates into slower acceleration in cars for which premium fuel is recommended.
