What Is The Difference Between 87 And 89 Gas? What is the difference in octane levels? Octane is how much compression a fuel can withstand before igniting, or rather it’s a measurement of a fuel’s ability to avoid knock. Typically “regular” gas is 87 octane, “midgrade” is 89 octane and over 91 octane is “premium” gasoline.
What happens if you put 89 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.
Can 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.
Does 89 gas burn slower than 87? These octane level numbers (87, 89, 91, etc.) Lower octane gas burns quicker than higher octane, and so require less energy to ignite.
