Whether you’re just perusing our new BMW inventory or you’ve got a BMW X3 and you’re wondering which fuel is best, BMW of Montgomery is here to help. And while you can put regular fuel in your BMW X3 in a pinch, overall it is recommended that you use premium fuel to maintain performance and efficiency in your BMW SUV.

Premium Fuel Preferred in the BMW X3

The BMW X3, like many other BMW models, is designed to run on premium gasoline with an octane rating of 91 or higher. This is because the X3 has a high-compression engine that requires higher-octane fuel to prevent knocking and maintain optimal performance. Using regular gas with a lower octane rating can cause the engine to knock, which is a metallic pinging sound that indicates premature ignition of the fuel in the engine's cylinders.

If you accidentally fill up your BMW X3 with regular gas, you may notice a decrease in performance and fuel efficiency. The engine may also produce a knocking sound, which can be damaging over time if left unchecked. In Montgomery, AL, where summer temperatures can soar, using the correct fuel is especially important to prevent engine knocking and maintain the longevity of your vehicle.

While using regular gas in your BMW X3 may not cause immediate damage, it can lead to long-term issues if done repeatedly. The engine's components may experience increased wear and tear, potentially leading to costly repairs down the line. It's always best to follow the manufacturer's recommendations and use premium gasoline to ensure your X3 performs at its best.
