In most cases, the vehicle will run fine, but you may experience less power and a decrease in gas mileage. In more serious cases, you may hear engine knocking or valve chatter because the fuel isn’t burning right. These things could damage your engine and you should take it to your mechanic.
So, what kind of gas does a BMW take? As we said, the best gas for a BMW is premium. Premium gasoline is the best gas for BMW models because of its higher octane rating which also is a more seamless fit with a high compression engine. While regular gas only has an octane rating of 87, premium reaches up to 92.
Can I put 89 gas in my BMW?
BMW requires 91-octane fuel at a minimum, with 93 recommended, so we did just that, switching between the common forms of premium gas depending on which state you’re in.
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. When you put regular gas in a BMW as opposed to premium, the car will recognize this and may run with a little less power and less timing but all components will work properly.
Can you put 87 in a BMW?
The short answer is: NO! We do not recommend running low grade fuel in BMW’s. While a few models might present this as a viable option when reading the owner’s manual, Triangle Imports does not believe in that philosophy. The possible negative effects on your car from using regular fuel simply aren’t worth it.
What happens if you put 89 gas in a 87 car?
“If the octane is less than 91, the engine could be damaged and the repairs would not be covered by the vehicle warranty. If heavy knocking is heard when using gasoline rated at 93 octane, the engine needs service,” the owners manual reads.
Luxury cars may require premium gas if they have a high performance or turbocharged engine. Even if you’re not buying a luxury car, more luxurious trim levels for a car may offer engine options that require premium gas.
Gas stations in the United States generally offer three octane grades: regular (usually 87 octane), mid-grade (usually 89 octane), and premium (usually 91 or 93 gas).
Citing World Toyota’s Service Center, 11Alive reported drivers should not put regular gas in a vehicle that takes premium because the lower octane levels found in unleaded gas could create “knocking” that damages the vehicle’s motor. It may also void your warranty.
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.
No matter your model, BMW recommends using only premium-unleaded fuel. That’s not to say your BMW won’t run on lower-grade fuel, but premium-unleaded fuel will maintain its quality in the long run, letting you drive at peak performance consistently.
Is there really a difference between 87 and 91 octane?
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.
What gas station is best for BMW?
Because Shell paid more money to be the official fuel recommended by BMW. It’s all about the marketing dollars and has nothing to do with the product being good, bad, or better. I have never had any issues with it and I start with it in my first tank of gas . Throughout my ownership, I never use any other brand.
What happens if you 87 instead of 91?
“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. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.”
Can you run 87 in a BMW 328I?
87 is fine in a 328i. I use it whenever the 87/93 price differential gets much above 10% as it becomes more cost effective, even given the poorer performance & fuel economy.
Today’s premium fuels contain additives and detergents that help clean fuel injectors and remove carbon deposits inside of engines, thus, incentivizing motorist with engines that use regular fuel to, on occasion, use premium gas to clean their engines.
Is Costco gas good for BMW?
We use Costco gas in all our BMW and other cars. I even use it in my Bmw m8 v8 with twin turbos. It’s perfect and works well. Kirkland Signature gas meets all Top Tier requirements, including Regular, Premium and Diesel.
The kind of gas a BMW 328I takes is premium gasoline with a 97 or higher octane rating—in fact, the BMW 328I is one of the few models that BMW actually requires to use premium fuel, rather than simply recommending it.

Does 89 last longer than 87?
Sadly, there’s nothing in premium gasoline that would make it last longer than other fuels from the pump. Since the distinguishing feature is the higher-octane levels, the only real benefit you gain is lowering the chance of engine knocking, which isn’t much of a threat on most modern fuel systems.
Fuel with an 87 octane rating burns more quickly while higher-octane fuels burn more slowly. In engines designed for standard unleaded fuel, efficiency and performance is optimized for 87 octane and could actually perform worse with higher-octane fuel since the burn rate is slower.
Does 87 or 89 get better gas mileage?
Regular gas typically has an 87-octane rating, and the 88-90 range is considered midgrade. While premium gas drives performance in certain engines, the idea that it’s more fuel efficient is a myth. Any fuel efficiency gained would stem from engine performance and not the gas itself.
Does higher octane gas give better mileage?
So is Higher Octane Fuel More Efficient? In a word, no. On its own paying for premium gasoline does not make your car run better or get greater gas mileage. Giving your car the fuel it requires to run smoothly and efficiently, without damage to the engine, does make a difference in your fuel mileage.
No, premium gas does not last longer than regular gasoline in a fuel tank. A car owner might only consider the longevity of a car’s gas if the vehicle has been sitting unused for an extended period.
What’s the difference between 93 and 87 gas?
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.
