Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 230i.
The 2021 BMW 230i enters the reference record as a model year running an eight-speed automatic and requiring 5.5 quarts of 0W-20 engine oil, with EPA ratings of 23 mpg city, 33 mpg highway, and 27 mpg combined framing its efficiency profile. These service and consumption numbers form the practical baseline a researcher needs before situating the car within its segment, since oil capacity and viscosity define routine maintenance while the combined mpg anchors operating-cost comparisons. Because the overview supplied here contains no reliability survey data, any reading of where the 2021 model year sits in the 230i's long-term dependability arc should be drawn from published owner surveys and warranty-claims records rather than inferred from these specifications.
