What happens if you use 93 octane 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.
Is it bad to switch gas types?
No, you won’t damage it. The “recommended” means the engine has a knock sensor, and the timing will be adjusted to compensate for the lower octane gas, at some decrease in performance and efficiency.
Does using 93 octane make a difference?
In a consumer notice, the Federal Trade Commission, notes: “In most cases, using a higher-octane gasoline than your owner’s manual recommends offers absolutely no benefit. It won’t make your car perform better, go faster, get better mileage or run cleaner.”
What fuel should I use in my car?
If your car recommends regular 87 octane gas, you’re in luck. You can safely use the cheap stuff. Premium fuel won’t make the engine run better or produce more power.
What is 87 octane gasoline made of?
The common fuel ratings (87, for instance) refer to the composition of gasoline. 87-octane gasoline is comprised of an 87 percent blend of isooctane and 13 percent n-heptane, or a blend that’s equivalent.
What happens if you put 89 octane fuel in a car?
If so, keep using 89-octane to regain some power and save your engine. If your car requires premium, then you should fill it up with premium because if you run lower octane fuel, your car will have less power and lower fuel efficiency. If you use a lower octane fuel it can lead to engine knock as well as increased emissions.
What does higher octane mean for gasoline engines?
It does not mean “harder-to-ignite” or “hotter burning.” A gasoline engine will not perform worse in any way on higher-octane gasoline. The higher-octane outputs of a gasoline refinery have only been reformed to be more knock-resistant.
What is the difference between cetane and Octane?
In the cetane number scale, high values represent fuel that ignites readily and, therefore, performs better in a diesel engine. In the octane number scale, high values represent fuels that resist spontaneous ignition and, therefore, have less tendency to knock in a gasoline engine.
