I drive a 2005 Subaru Outback 2.5XT, with about 190k on it. Now, this car is AWD, Turbo Charged, and takes premium, I don't expect amazing fuel mileage like my old civic. I do mostly city driving, short trips (less then 5 minutes) and my ride to work is 10 KM on the highway. My car computer says I'm getting 10-12 MPG on average, and I usually get 170 miles from my 52 litre tank of premium
I don't have a garage, so it's kind of hard for me to do any work myself, but I'll be driving to Calgary in the future and can tear it apart with my dad and try and fix whatever is causing this abysmal mileage. Can anyone give me a list of things that I should start with? Oil Change, sparks plugs, air filter... after those easy things, what should I start checking? The 02 sensor maybe?
Appreciate any advice.
