2005 BMW 330I
Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2005 330I.
Transmission Automatic (S5)
The 2005 BMW 330I sits on the classic E46 chassis, powered by a robust inline‑six that requires 6.9 qt of oil—available in 15W‑40, 10W‑40 or 10W‑30 API SJ grades—while delivering EPA ratings of 17 / 25 / 20 mpg city/highway/combined under an automatic S5 transmission; in the broader 1999‑2011 reliability window, the 330I’s 2005 iteration falls neatly within a period that saw its highest and lowest complaint counts both at 121 in 2001, indicating a relatively steady, if not exceptional, durability profile for that generation.
