Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2009 550I.
Transmission Automatic (S6)
The 2009 BMW 550i rides on the E60 platform and pairs its engine with a six-speed automatic (S6) transmission, returning EPA fuel economy of 15 city, 23 highway, and 18 combined mpg. Service requirements call for an 8.5-quart oil capacity filled with 15W-40, 10W-40, or 10W-30 API SJ lubricant. In the 2011–2015 complaint record, this model year peaked at 172 filings in 2011 before dropping sharply to just 6 by 2014, placing the 2009 car toward the more reliable end of its documented history.
