MPG Problem


New member
Hey Ladies & Gents,

Got a curious problem... I have a 2011 Subaru Legacy 2.5i Premium and the specs on this Veh states that I should be getting 27 hwy miles per gallon and it has a 18.5gallon tank.  I travel 74 miles to and from work, Monday - Friday... which calculates to 380 miles a week give or take a few. 

The problem I'm having is that I use an entire tank of fuel in four days, while driving like a pepe.  So a full tank of fuel should be giving me approximately 499.5 miles and I travel 380 miles a week (Five days)... and yet... I use an entire tank of fuel in just four days! 

So, I'm just wondering what do y'all think it could be?  Also, fyi... I just purchased this car from Evergreen Subaru approximately three months ago, so everything was checked and deemed good.

So, what do y'all think?

Thank you.

4 days on a full tank is pretty good . No way would you get 500 miles on a tank . Unless your pushing the car I avg 25-28 city and rufly 30-32 on hw . This was on summer gas . Winter gas you will get worse millage this was on my 11 2.5i ..
