What type of gasoline should be used for the BMW X5?
2 Answers
It is recommended to use 98-octane gasoline for the BMW X5, as it ensures better engine performance, reduces carbon deposits from combustion, and can extend the engine's lifespan. Below are some details about the BMW X5: 1. The BMW X5 is the brand's first four-wheel-drive SUV model, launched in the United States at the end of 1999. It has a wheelbase of 2933mm, a weight of 2200 kg, a top speed of 250 km/h, and features front-engine, four-wheel-drive with a displacement of 2.9L. 2. The BMW X5's greatest advantage is its exterior design, which continues the family characteristics of BMW SUVs, showcasing BMW's design elements throughout, with outstanding features like the panoramic sunroof and angel-eye headlights.
I've driven a BMW X5 for several years and found that it indeed requires high-octane fuel, with the official recommendation being 95-octane unleaded gasoline as the minimum. Initially, I thought 92-octane would suffice, but after trying it once, I noticed the car felt somewhat sluggish, and the engine made slight unusual noises when climbing hills. Later, I checked the owner's manual, which emphasized using 95 or 98-octane fuel because the X5's engine has a higher compression ratio. Insufficient octane levels can cause knocking, and in severe cases, may damage the spark plugs or cylinders. Now, I consistently use 95-octane fuel, especially when accelerating to overtake on highways—the power delivery is much smoother, and fuel consumption remains stable at around 12 liters per 100 km. I’d like to remind everyone to pay attention to fuel quality at gas stations. Some smaller stations offer cheaper fuel but with more impurities, which can harm the car over time.
