What grade of gasoline should a BMW 328 use?
1 Answers
BMW 328 uses 97-octane gasoline. Definition and composition of gasoline: The English term for gasoline is 'gasoline' or 'gas' (American English), also known as 'petrol' (British English). It is a volatile, flammable hydrocarbon mixture liquid derived from petroleum through fractionation, cracking, or pyrolysis, primarily used as fuel for spark-ignited internal combustion engines. It mainly consists of organic compounds obtained from crude oil fractionation and various additives. Function of gasoline: The octane rating of gasoline measures the anti-knock properties of a specific gasoline mixture (which can cause knocking and reduce the efficiency of reciprocating engines). Depending on the octane rating, gasoline is produced in several grades. Other chemicals are often added to gasoline to improve chemical stability and other performance characteristics, control corrosiveness, and maintain the cleanliness of the fuel system.
