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.  We believe it’s best to use premium gas. Let’s get into the details.

BMWs have been one of the most popular luxury cars on the market for over 100 years. As with most luxury cars, they cost more to own than other vehicles. Parts, maintenance, and even gasoline all come with a heftier price tag.

As a BMW owner, you’ve probably wondered if there is anything you can do to save money without giving up the car you love. Skimping on maintenance isn’t optional, but why not premium gas?

Premium Gas vs. Regular

“Premium” and “Regular” refer to the amount of octane in the gasoline. Premium is higher octane, typically 91-93. Regular gas is lower octane, usually 87 or 88.

High octane fuel can withstand higher compression than lower octane fuels. This is especially important for people that drive cars with high-compression engines, like some BMWs. 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.

The Downsides of Using Regular Gas in Your BMW


Filling up your BMW, or any other car, with premium gas can hurt your wallet. Depending on your BMW model, you can technically save money by using regular fuel, but it will come at a cost. We believe enjoying those savings now isn’t worth risking damage to your vehicle. 

Most modern BMWs can run on regular gas, thanks to more electronic components, but this can place stress on parts including electronic knock sensors in your engine. These electronic components allow the engine to detect the type of gas it’s running on and adjust performance accordingly, avoiding damage to your engine. 

Another downside of using regular fuel is that because it adjusts your engine’s performance, you’ll lose some of your car’s power and experience slower acceleration rates. This isn’t a huge loss, though. Most cars that are recommended to use premium but switch to regular gas will lose in the neighborhood of 10HP. This probably isn’t a big deal if you just rely on your Bimmer to get you around town, but it’s important to keep in mind, especially if you bought your BMW for its power.

Like anything, there are some exceptions to this rule. Some BMWs do require premium gas.

These are the most common reasons a Bimmer may require premium, but is by no means an exhaustive list. Don’t use regular gasoline in your BMW if it falls in one of the following categories:

  • Your car is older than model year 1996
  • It’s an M model
  • It has a high-compression and/or turbo engine
  • BMW requires that your model car run on premium gasoline (they recommend that all of their cars use premium, but only require it on select models)

Here you can find a full list of BMWs (model years 2012-2019) that require premium and here is a list of BMWs that recommend premium, but will run on regular. Don’t forget though, running on regular can have consequences as we mentioned previously. Above all, always check your owner’s manual before switching from premium to regular unleaded.
