The BMW X3 is a stylish and capable compact luxury SUV that delivers thrilling performance. Many San Jose BMW enthusiasts considering the X3 have questions about the recommended fuel type and whether premium gas is really necessary. Before you buy a new BMW X3 in San Jose at Stevens Creek BMW, learn more about the SUV's recommended fueling methods.

BMW X3 Models Require Premium Gasoline with an Octane Rating of 91 or Above

According to BMW, premium unleaded gasoline with an octane rating of 91 or higher is required for the X3. This applies to both the X3 30 xDrive and X3 M50 xDrive models. Using regular gas with a lower octane rating can cause engine knocking and may even lead to damage over time. Be sure to fuel up your BMW X3 with premium gasoline at San Jose pumps.

Why Premium Gas Is Recommended for the X3

The BMW X3's sophisticated turbocharged engines are designed to run most efficiently on high-octane premium fuel. X3 30 xDrive models are equipped with a 2.0-liter BMW TwinPower turbocharged four-cylinder engine producing 255 horsepower, while the X3 M50 xDrive packs a 3.0-liter BMW TwinPower turbocharged inline-six engine with a 48-volt mild hybrid system that generates an impressive 393 horsepower.

These high-performance engines have a higher compression ratio than regular engines, which means the air-fuel mixture is squeezed to a greater degree. Premium gas is more resistant to pre-ignition and knocking under these conditions. Using lower-grade gas can cause the engine to run less efficiently and may trigger the knock sensor to adjust timing, resulting in reduced performance.

The Impact on Fuel Economy and Performance

While premium gas costs more than regular, the difference in price is justified for BMW X3 owners from San Jose who want to experience the full performance potential of their SUV. The new BMW X3 earns up to 33 highway miles per gallon taking the Bayshore Freeway, I-280, or the San Thomas Expressway through San Jose.

Using regular gas may slightly improve fuel economy, but it comes at the expense of performance. The X3's engines are tuned to run on premium, so using a lower grade fuel can result in slower acceleration, reduced power output, and even poor fuel economy if the engine isn't running optimally.

Filling Up Your X3 in San Jose

If you're driving a BMW X3, you'll have no trouble finding South Bay gas stations that offer premium fuel. Most major brands like Shell, Chevron, and 76 carry premium gas at their pumps. Stick with reputable Top Tier gas stations to ensure you are getting high-quality fuel for your X3.

When filling up your X3 with premium gas, you can rest assured that you are giving your SUV the best possible fuel for peak performance and longevity. While it may cost a bit more per gallon, using premium fuel as BMW recommends is the right choice for this premium luxury vehicle.
