Decent fuel mileage is possible with the 4.6 2 wheel drive. My 08 STA will drop down to 18-20 mpg on hilly terrain and some combination driving. If there is a lot of idle time, it will drop quickly. On the highway at 65-70 w/o cruise and level terrain, anywhere from 24-28 usually averaging 26. Please note, it does have a K&N CAI, Gibson 3" exhaust, Zabtech throttle body and 275/55-20 Michelin LTX/MS tires (32").The oversize tires changes the final drive ratio from the 3.55 with stock tires to about 3.31 or thereabouts with the larger diameter Michelins.. I run 36 lbs of air pressure. The speedometer was calibrated for the oversize tires. I also use Valvoline 5-20 full synthetic oil. This vehicle has 30,000 miles on the clock.
I am considering a specialized tune to try and get a little more mpg out of it,but so far I'm pretty satisfied.
