What grade of gasoline should a BMW 525 use?

[IsabelleAnn]

BMW 525 requires gasoline with an octane rating of 95 or higher. Mixing gasoline of different grades will not cause a chemical reaction, as the octane ratings vary. Higher-grade gasoline has a higher octane rating, which also means better stability. Many car engines require high-grade gasoline to prevent engine knocking. The dimensions of the BMW 525 are 5047mm in length, 1860mm in width, and 1491mm in height, with a wheelbase of 3108mm. This model comes standard with features such as all-around airbags, auto-dimming rearview mirror, automatic high-beam control, active protection system, aluminum roof rack, electric front seat adjustment, third-row seats, keyless entry, trunk storage kit, smart touch key, and intelligent ambient lighting.
