What type of gasoline should a BMW X5 use?

[MacAdaline]

BMW X5 is best suited for 98-octane gasoline, which ensures better engine performance, less carbon deposits from combustion, extends engine lifespan, and provides more stable operation. Here is additional information: 1. 98-octane gasoline: 98-octane gasoline refers to fuel with an octane rating equivalent to a mixture of 98% isooctane and 2% n-heptane. It offers higher anti-knock properties and better power output while producing fewer harmful substances and lower exhaust emissions. Due to its high octane rating and premium price, it is primarily used by luxury vehicles and is often referred to as "premium gasoline." 2. Considerations: Although 98-octane gasoline is superior, it is not suitable for all vehicles. Generally, vehicles with fuel tank caps labeled "Please use 95-octane or higher gasoline" can use 98-octane fuel. Additionally, vehicles with an engine compression ratio of 10 or higher are also suitable.
