What happens if you put premium gas in a regular gas car?
The octane rating of gasoline determines when the engine combustion will occur at a wrong time. An occasional ping most likely will not harm your vehicle, but repetitive knocking demise the car’s engine. Perhaps because of this condition, earlier people put premium gas in a regular gas car.
Does my car really need premium gas?
In many cases, the answer is probably no — you’ll likely be able to use regular fuel with no noticeable issues except for minor losses in performance and gas mileage. If your owner’s manual says that premium fuel is required, then you should do it, but your car won’t blow up if you occasionally opt for regular.

Is it bad to put 87 in a car that takes 91?
As long as you are not running wide-open throttle, this is of little immediate consequence in a naturally aspirated engine. In a turbo or super-charged engine, you have a high risk of pre-detonation under boost & WOT conditions due to the lower octane.
What happens if you put the wrong gas in your car?
For gas/diesel mix-ups, a prompt drain is necessary to prevent internal damage to your car. In cases of filling up your car with the wrong octane of fuel, your car usually compensates so that no immediate damage may happen. However, it is important that you fill your engine up with the correct fuel right away.
Can premium gas hurt my engine?
Yes you can, but it’s a waste of money. Run the lowest octane that your car will run optimally. Many cars today have knock sensors so running regular gas in a car that recommends premium is ok, with reduced performance. Compression is one indication of whether or not you require premium.
What happens if you put 93 gas in a 87 car?
If your car is designed to burn 87, it will not burn 93 correctly. Third, your gas mileage will suffer. The inability of your engine to burn the higher octane gas correctly will cause your engine to produce less power and thus will require more fuel to perform at the same level.
Is it safe to mix regular and premium gas?
Save On Mid-Grade Gas By Mixing Regular And Premium. If you put mid-grade gas in your car, it’s actually cheaper to pump in a mixture of premium and regular to get the same octane level. It’s perfectly fine to combine different octane levels of gas, as long as they’re both unleaded.
What happens if you don’t put premium gas in a BMW?
“There generally isn’t any harm done to the engine by using lower-octane fuel,” said a BMW spokesman, Thomas Plucinsky. “Because our engines do have very good forms of knock sensing and are able to deal with lower-octane fuels, you will not have any drivability issues. You will, however, lose some of the performance.”
Why do some cars require premium gas?
When a vehicle manufacturer requires using premium fuel, it is because that particular vehicle’s fuel system is designed to work best with higher octane gas. Using regular gas in an engine that requires premium could void your warranty. “Use premium unleaded gasoline with a posted octane rating of 91 or higher.
What happens if I don’t use premium gas?
Don’t use cheaper gas in cars if premium fuel is required, experts say. LOS ANGELES — With fuel prices on the rise, some drivers are pumping less-expensive regular-grade gasoline into cars for which premium fuel is recommended. Knocking, in which gas burns out of synch with an engine’s timing, can damage the motor.
