BMW 5 Series requires gasoline with an octane rating of 95 or higher. Below is a detailed introduction about the BMW 5 Series: 1. Overview: The domestic 5 Series is a high-end sedan, with the current generation introduced in 2004. The BMW 5 Series is one of the most outstanding series in automotive history. Its peak era began with the third-generation E34 (1988-1996). The current 5 Series is the third-generation product of the E34. 2. Other Features: The main advantages include a grand and beautiful exterior; a stable interior with good craftsmanship and rich configurations; spacious interior. The main drawbacks are the subpar interior materials. Some vehicles may experience oil burning issues. The exterior dimensions of the BMW 5 Series are 5047*1860*1491 (mm), with a wheelbase of 2888 mm.
I've been driving a BMW 5 Series for several years and always follow the manufacturer's fuel recommendations. The fuel filler cap states to use 95 octane or higher, so I mostly use 95 octane, and the power response is very smooth. Occasionally using 98 octane doesn't feel much different, but if I try to save money by using 92 octane, the engine sound becomes muffled, and acceleration isn't as sharp. A special reminder for northern car owners: using 95 octane in winter helps prevent fuel condensation better. Always check the pump label when refueling, as many gas stations place 98 and 95 octane pumps very close together—don't mix them up. Long-term use of lower-octane fuel can affect engine lifespan and worsen carbon buildup issues.
