F10 / F11 (2011 - 2016) The sixth generation of the BMW 5 Series Sedan (F10) was produced from 2011 - 2016 with LCI updates arriving in 2014. In the US BMW offered a hatchback 5 Series Gran Truismo (F07) and the rest of the world also go a Station Wagon/Touring version F11.
I have one local station with NO ETHANOL 91; if I can't there. by 2nd choice is Shell 93 Octane (has ethanol in my area). Noticed a huge difference in performance with the non-ethanol on my 2010 535I, not quite as much on on the 2011 535I.
Ethanol is a HUGE performance killer. You're lucky to find ethanol-free fuel.
