BMW 3 Series uses 95 octane gasoline. If 95 octane gasoline is unavailable, 92 octane gasoline can be used as an emergency measure, but this is only permissible when driving at medium engine speeds and under low engine load. Here is some additional information: 95 octane gasoline consists of 95% isooctane and 3% n-heptane. High-octane gasoline should be used in engines with high compression ratios. BMW is a German luxury car brand, with model series including i, X, Z, and pure numeric models, as well as the M series, which is based on improvements to these series. The BMW 3 Series has a body weight of 1,465 kilograms, is equipped with an inline 4-cylinder gasoline engine, and has dimensions of 4,734mm in length, 1,811mm in width, and 1,455mm in height.
