Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 325CI.
The 2006 BMW 325CI is an E46 platform vehicle that routes power through an automatic (S5) transmission, returning an EPA-rated 17/25/20 mpg across city, highway, and combined driving. Sustaining this engine requires a precise 6.9-quart oil capacity utilizing 15W-40, 10W-40, or 10W-30 API SJ viscosity to maintain proper internal lubrication. As a 2006 example, the vehicle occupies a mature stage in the model's reliability history, meaning its long-term dependability is highly predictable and fundamentally dependent on strict adherence to these established maintenance specifications.
