tjxtreme Posted May 9, 2007 Share Posted May 9, 2007 With the arrival of spring, I have noticed a definite rise in gas mileage of my outback 2.5 with 130k miles. Today, I measured 28 on a whole tank of hwy miles. Since EPA hwy estimate is 27, and those are often criticized for being inflated, I have the following hypotheses: 1. AWD is possibly just FWD... how do I check (aside from peeling out in a mudpuddle while looking back out the window)? 2. Increased gas prices have led me to drive even more conservatively- accellerating slowly, keeping very very steady rpms on the hwy, and coasting to a stop instead of gassing it and then stomping the brakes.

porcupine73 Posted May 9, 2007 Share Posted May 9, 2007 It may just be the change to summer gas and increased ambient temps. Even if the AWD is just in FWD it does not give increased mileage. All the AWD sundry is still turning and dragging. My all time best record on summer gas in good temps on 2.5L '00obw is 30mpg on a 200 mile trip. Average is 27-28.

porcupine73 Posted May 9, 2007 Share Posted May 9, 2007 But there are so many possible variables for fuel mileage that to get a good reading they must be minimized. i.e. same grade at the same pump from the same gas station driving in similar conditions with similar ambient temps, etc, averaged over a number of trips. But maybe you're already doing that. The EPA or whoever authorizes sale of winter gas in certain areas from November I think to sometimes in spring. The first time I heard of it was when there were those gasoline shortages from that hurricane in New Orleans and they allowed winter gas to be sold early.

dmanaenk Posted May 9, 2007 Share Posted May 9, 2007 Check your tire pressure, if it was up to specs in winter it is most likely too high now, which increases mpg. Link to comment Share on other sites More sharing options...
Manarius Posted May 9, 2007 Share Posted May 9, 2007 I got 27mpg going back and forth to Philly (180ish miles round trip) with my 2.2L Legacy fully loaded down with 4 people and stuff (that was averaging 80-85 down the turnpike). Link to comment Share on other sites More sharing options...
LosDiosDeVerde86 Posted May 9, 2007 Share Posted May 9, 2007 1. AWD is possibly just FWD... how do I check (aside from peeling out in a mudpuddle while looking back out the window)? trust me.. if the AWD wasn't working you'd know it. you'd peel out at almost every stop, nevermind a mud puddle.

baccaruda Posted May 9, 2007 Share Posted May 9, 2007 my EA81T is getting better mileage lately as well. Probably seasonal factors. Link to comment Share on other sites More sharing options...
Suzam Posted May 9, 2007 Share Posted May 9, 2007 Could be the way you are driving. I can beat the wife's milage in the same car almost all the time, just by having different driving habits. Link to comment Share on other sites More sharing options...
nipper Posted May 9, 2007 Share Posted May 9, 2007 Sounds normal, now if you said 40 i'ld steal your car. EPA figures are just a guide, your milage may be higher or lower depending on how you drive, speed and weather. If i hold blu to 50 i can see 32 mpg, but typical on the highway (65-70) is 26. 1mpg +/- doesnt mean anything in the big scheme of things. You would know rather quickly if your AWD is not working,like stated above. nipper Link to comment Share on other sites More sharing options...

porcupine73 Posted May 10, 2007 Share Posted May 10, 2007 Hm...anyone know what states are left, if any, that don't put ethanol in their gasoline? In NY it's supposed to contain 10% (instead of MTBE). Link to comment Share on other sites More sharing options...
