You’ll most likely notice the spark knock (a sort of high-pitched pinging or rattling noise). Luckily, the engine computers can adjust the timing to limit the amount of damage caused, but you’ll definitely notice lower fuel economy and reduced performance in your vehicle.
What happens if you accidentally put the wrong gas in your car?
Typically, although there are some variations among engines, putting a higher-octane gas into your car than it requires will neither help nor hurt your car’s performance. This mistake should not cause any major damage to your car – just be sure to pick the correct octane gasoline next time you fill up.
Can the wrong gas mess up your engine?

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 may feel a difference in the way the vehicle runs and may notice an improvement in gas mileage, but that’s about all that will happen.
Can mixing different gas damage your car?
Can I mix premium and unleaded 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 happens if you mix regular and premium gas?
You can mix regular and premium gas to get a mid-grade octane. In fact, this is what most pump stations do to get a mid-grade-level octane gas. However, mixing premium and regular in a premium car will reduce efficiency and cause it to lose its power.
Can I mix 87 and 89 gas?
Is it okay to mix 87 octane and 89 octane fuel together in my car? 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.

Will unleaded 88 hurt my car?
A: Unless the owner’s manual says your car can handle 15 percent ethanol, you could harm your engine in the long run. The 88 octane should have no effect if you happened to fill you tank with it once, but prolonged use by a car not equipped for it can cause an engine to wear out faster.
Does the type of gas matter?
Which Type of Fuel Should I Be Using? The answer is the cheapest fuel that your car’s engine is designed for. Premium gas won’t improve your engine’s performance or produce more power if your car was designed to operate on regular octane gas.
What happens if you put 85 gas in a 87 car?

What happens if I accidentally put regular gas in my Mercedes?
If you mistakenly fill up with regular fuel, your car’s ECU will adjust engine timing and performance to work with the lower-octane fuel. In most cases, this is ok for the times when there are no premium pumps around, but it’s not ideal to run the cheapest fuel possible for extended periods of time.
Can you mix 95 98?
While this is unlikely to cause major damage to your car, the RAC recommends sticking to the octane recommended for your vehicle. A spokesperson for the AA said: “Mixing the 95 and 98 octane fuels will not cause any problems.”Dec 17, 2021.
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. It’s the fuel’s ability to be compressed more without pre-igniting that results in more power when used in the appropriate engine.
What happens if you put 87 in a BMW?
Regular gas is lower octane, usually 87 or 88. High octane fuel can withstand higher compression than lower octane fuels. Putting low octane fuel in a car with a high-compression engine could cause the engine to knock or ping, which could cause major damage if it goes on for a long time.
