So far first tank of fuel and the on board is saying 25.6 mpg this is mixed driving here in the DFW area. I have like just over 260 miles on my car.

22-23mpg so far. Pretty spirited driving too.

yeah, the mileage calculators tend to be a little high - mine reads 1.7 mpg higher than actual mpg...

Did Tylers65 ever get over 30 mpg on a full tank? He was used to squeezing out high mileage with a Prius. I assume his XB was a manual.

Mine was like that for a long time till I drove out to vegas. Now its 25-26 with combined city-highway driving.

are you doing mostly city driving or what BigMikeLV?

i get similar mileage in town but we have lots of traffic lights and i rarely drive on the freeway...

I have 11K on my xB and during my commute to work [which consist of 12 miles of light traffic (through multiple stop signs and 18 stoplights) and 9 miles of highway @ 65mph] I always manage to get ~33mpg.  Last month I set a goal to maximize my mpg as much as possible and raised my average to 35.5mpg during 3 tanks.  All my calculation have been miles traveled/gallons used, as I've found that my trip computer is always ~5% optomistic.  I've taken several hwy trips as well and got ~32 mpg going with the flow of interstate traffic 65-80mph.  I'm running on regular dino oil and have tires set to 36 front, 33 rear.  Next oil change will be sythetic, so we'll see if it makes any difference.

I got 23 the first couple of tanks but the last tank was 25.6. Automatic with 55% hwy. I try not to go over 67 on the hwy to work to keep the RPM's down.
