Don't worry too much about it. It will increase after a while. Even I got quite less mpg (~22) for first couple of tanks. Now I'm getting ~24 in 100% city driving and ~31 on highways.
Although I must add, it highly depends on your driving style, terrain and traffic.
Mine is MT...when driving a manual I naturally let it rev more than when I drive AT...but it seems you guys are getting worse mileage.
My 25ish is also letting it run when taking the kids into daycare since its winter and the daycare is 2 min from my house (want it to heat up properly)...so that is idling for 10min a morning just burning fuel.
Same....8 L/100km or 29 mpg with a HEAVY foot. If I take it easy than 33 mpg no problem...also MT. I think the break in has a lot to do with its mileage. Don't worry about babying it too much (don't be afraid to put your foot into it), just don't redline it when cold, or when under the 1000 mile/1600 km break in. Also search the threads for break in advice other than what the manual states. Enjoy though!
I would take all these numbers with a grain of salt. Also, for the AT people - it seems most of you still haven't broken in the vehicle yet. I would expect your numbers to greatly increase as you put the miles on the car.
There are so many factors that determine gas mpg that it's hard to really compare. Sea level, type of gas, how hard you drive, engine wear, road conditions, weather, etc etc. Give it a few months to really see where your numbers are. Mine is around 25 avg mpg according to the computer but it was lower when I was breaking the vehicle in. MT
I drove over 280 miles today; just reaching 930 total.
Much of the driving was at high speed on back road twisties, with a bit on the freeway @ 75 mph for the final few miles.
I filled up at the same pump in the morning and again this evening ... 31.2 mpg.
I'm impressed; as I pushed well past the 4k break-in threshold several times.
I should pass the thousand mile mark soon. We'll see what happens when I raise my shift point on a regular basis ...
