Can I use 87 octane instead 91?
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 91 gas the same as 93?
Premium gasoline is generally considered any type of gasoline with an octane level of 91 or greater, with 91 octane and 93 octane being the most common versions of premium gasoline available at gas stations in the United States (93 octane gasoline may be called “ultra” or “super-premium” in some cases).
Can you mix 89 and 91 gas?

What happens if you put 87 octane in BMW?
Premium is higher octane, typically 91-93. Regular gas is lower octane, usually 87 or 88. 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.
Does BMW really need premium gas?

What happens if you put regular 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.”
What happens if you put premium gas in an unleaded car?
Putting Regular Fuel in a Car That Requires Premium Using lower octane fuel in a vehicle that requires premium gas could cause some serious internal damage. You’ll most likely notice the spark knock (a sort of high-pitched pinging or rattling noise).
Is it bad to switch from premium to regular gas?
It’s a different story for a car whose engine requires premium fuel. The car will run on regular fuel in a pinch, but you shouldn’t make a habit of it. The fuel’s lower octane can result in elevated exhaust-gas temperatures and possible knocking, both of which can adversely affect the engine’s health in the long run.
