use 91 or higher, cheaper gas saves you at the pump but you get less performance and less mileage since everything for timing and all have to be changed and yield less mpg.


i have an 08 manual and get around 20-23 mixed, on highway i get around 28mpg if going around 80mph, if i can around 65mph i get up to 30mpg-31mpg.


auto sucks unless and srt, manual is much more fun and responsive.
