The BMW 325 is designed to run on premium unleaded fuel with a minimum octane rating of 91 as indicated by the manufacturer. The higher octane fuel is necessary for the engine to resist detonation better and achieve higher air compression, resulting in smooth operation. Using lower quality gasoline can lead to timing problems with the pistons, causing reduced performance and fuel efficiency. It may also result in a ticking noise in the engine due to inferior fuel quality. It is crucial to adhere to the recommended octane rating to optimize the longevity of your fuel system and maintain efficient operation.
