What happens if you mix 87 and 91 gas?
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.

Is it OK to 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. … Most gas stations that sell 87, 89 and 91 octane gas use what is called a mixer pump.
Which gas is better 87 89 or 93?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time.
Can high octane fuel damage an engine?
The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. … But if the vehicle manufacturer says your engine needs only 87-octane regular, that is what you should use.
Does premium gas burn slower?
Octane does not offer any better fuel mileage, increase engine horsepower, or make the engine start quicker. Higher octane only reduces the likelihood of engine knock or ping. … Because higher octane gas burns slower, it is more resistant to knock when subjected to higher RPM and cylinder pressures.
Does 110 octane go bad?
Fuels contain components that are sensitive to light; the octane rating of the fuel can drop if the fuel sees too much light. Perfectly stored, most race fuels will last more than a year. If you are not sure you can use the fuel up within 2 years, add a quality fuel stabilizer to the fuel as soon as you purchase it.
Does 87 octane damage engine?
“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. … They usually warn that using lower-octane gas could reduce performance and fuel economy.
Does premium fuel increase mpg?
But take note: the recommended gasoline for most cars is regular octane. In fact, 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 is the point of 89 octane gas?
Mid-grade fuel lies somewhere in between the other two grades, typically with an octane level of 89. The Federal Trade Commission says if your engine in pinging with regular gas, then upgrading to mid-grade may stop it. Only a handful of cars require or recommend mid-grade.
Is it OK to mix 93 and 87 gas?
By using higher octane fuel where lower is specified, you will create no problems with your engine. It does not (by popular belief) add any power to your engine, but will not harm it at all. … When you mix different octanes of fuel, you are either increasing or decreasing the octane of the fuel at hand.
What happens if you mix premium and regular gas?
It probably won’t hurt anything. If your car requires regular gas, the blend will have plenty of octane and detergent and may even run a little better or get a bit better mileage. If the car requires premium, the blend won’t have as much octane as it should.
Can you mix high and low octane 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.
Will 110 octane hurt my car?
EZ- Your engine is not set up to take advantage of 110 octane fuel, but it will definitely not cause your car to overheat. The higher the octane you use, up to a certain limit, the more resistant the fuel is to preignition/detonation/knocking, allowing an engine to run more ignition advance.
Is there a big difference between 87 and 89 octane?
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. Some states label top-tier gasoline with 93 octane as “ultra” gas.
Does high octane fuel burn hotter?
Higher-octane fuel does not burn hotter. It will not clean out deposits from an engine combustion chamber. And it will not provide any higher fuel economy. But an engine’s octane rating can change over time.
