Can you run 87 in a BMW 328i?

What happens if I put 87 gas in my BMW?
The short answer is – nothing. Most BMWs can run on regular gas so you aren’t at any risk of causing damage to your brother’s car.

Does it matter if I put 87 instead of 91?
The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane. 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.
Why do BMW require premium gas?
This makes high-octane fuel better for engines that create higher cylinder pressures during the combustion cycle. We call these “high-compression engines” for obvious reasons, and while some BMW engines do use very high compression, not all of them do.
What to do if I accidentally put 87 instead of 93?
It shouldn’t cause your vehicle any harm. The ECM (Engine Control Module) will compensate for the lower octane fuel. You might notice a drop in engine performance and possibly lower fuel economy; but nothing detrimental. Just run the tank down and then fill it with 93 octane.
Can you mix 87 and 91 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.

Other things to consider: failing to use high-octane fuel in your premium vehicle could cause engine knock or pinging, which sounds like there’s a large woodpecker under your hood; you could experience damage to your components; and using the wrong octant level could even void your warranty.
What happens if you put 87 gas in a premium car?
A higher-octane gas, such as premium, helps prevent engine knock. In older cars that require premium, The Drive reported, fueling with 87 octane would almost immediately cause the engine to start knocking. But newer model cars are better equipped to handle it.
Is 89 and 91 the same gas?
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.
What happens if you mix 91 and 89?
You get gasoline with the combined octane. If you mix a half tank of 91 octane and a half tank of 89 octane, you end up with a full tank of 90 octane. Unless you are driving a car that requires 93 octane, you won’t damage a thing.
Is 89 and 87 the same gas?

What happens if I use 95 octane instead of 91?
It can’t hurt your engine if you use a higher octane fuel. So, for example, if you use 95 or 98 in an engine designed for 91, that’s OK. However, it’s not acceptable to put in a lower octane fuel than the minimum recommended by the manufacturer. Using 91 in an engine designed for 95 or 98 is potentially destructive.
What happens if you put 93 instead of 95?
Switching between 93 and 95 is also not a problem, as the engine simply adapts its spark timing if driven close to the knock limit.
What happens if you put 95 instead of 91?

Some cars that need premium only need 91 octane, and others may require 93 octane. If the owner’s manual indicates premium gas is recommended, you can typically operate the vehicle safely on regular gas. Still, you may not reach the performance and fuel economy indicated in the car’s specifications.
Is it better to run 93 instead of 87?
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.
