Poor gas mileage

Ask the People Who Own One:

2010 - 2012 Subaru Outback

Does anyone have a remedy for poor gas mileage for 2.5 cvt 2011 Outback? Mileage went from 27 - 32 first, to 21 - 26 thereafter. Always serviced, use good gas, tires inflated, etc. it must have something to do with the engine or computer. All the codes check out. Really disappointed with this. I also noticed many others have the same problem. Thanks.

I don't own an Outback, but Fuelly says that based on over 5 million miles of driving, the MPG most people are getting in the 2.5 CVT is 25.21 MPG, which is about what you are getting. EPA rating is 24 MPG combined. Did you do any recent maintenance or are you running winter gas? Weather is a factor, too. Did you change your commute? Sitting with the car on kills gas mileage on cars that don't have the auto start-stop feature.

If you are in the northeast the weather has been mostly cold since December. Gas mileage will drop when temperatures are 40-50?F and will sink when temp are in the teens. Excessive idling doesn't help.

When temp drop so do tire pressures. I can almost one psi drop for each 10? drop. Tire pressures set at 38 at 60? will be in the low 30 psi range at 10?.

Fuel economy returns when the temperatures do in the spring.
