Help fuel mileage 320 km on a full tank!
Hello everyone Ive owned my 2013 compass since June 2015. After reading about the fuel efficiency on the compass I decided it was the suv for me, based on the expectations of 450 km city driving, and 500 to 550 km highway driving per full tank of gas. Off of my first tank I achieved 420km of a combination of 70% highway and 30% city, and it's been down hill ever since. I got the compass at 62000km and have put on 32000km. I've maintained my oil change schedule, I changed my spark plugs within a year of having the vechicle based on the dealer ships advice , and have replaced the air filter and cabin filter also. Pretty much for the last year and change I've been averaging 310 to 340 km per full tank.
When I'm filling up at Costco I've bumped into a few other compass owners and have asked how much mileage they get per tank, not one of them averaged under 450 km for mostly city driving, and the general consensus was that most got 500 to 550 km for a combination of city/highway. I recently went back to the dealership and they tried to lecture me on fuel efficient driving even though I told them I drive trucks for a living and have taking and have certificates for fuel efficient driving. There only other suggestion was that it could be a bad O2 sensor , but I would have to pay $150 to hook it up to the computer to check for that even tho I supposedly have 100k warranty on the vechicle . Anyways im very frustrated and let down with my compass hopefully some one here has some advice.
