Which Michelin tires do you have that you noticed the mpg drop with?
I also have a 2015 and also noticed an apparent mileage drop after installing new Michelins (the rebadged Defenders that Michelin supplies to membership clubs, labeled X-Tour AS).I have a 2015 Forester. My mileage dropped when I was forced to buy new tires. The OEM gave better mileage. My Michelin probably are safer. Mileage dies much above 70. At 65mph it is great. At 80 it is not. It was probably rated at 65mph. Great car but not perfect. Very happy with my first car I ever bought new. I have been buying cars since 1970.
Well, this is part of the problem. Bellingham is rather hilly compared to Reno, NV. I've driven in Bellingham and some of those streets are very steep (e.g. Alabama St.); they will absolutely kill your MPG. So, if you're just driving around town in a relatively hilly city like Bellingham, the MPG you're seeing is nothing out of the ordinary and would be expected.Bellingham, WA
When comparing the dash display to a manual mpg calculation, I've found that my Forester's computer calculator overstates fuel economy by about 5%. That's why we call it the exag-o-meter.Is it safe to say the computer is pretty accurate?
You should be thrilled, if getting the best fuel economy of any car in its class is something that thrills you.I'm not thrilled with my mileage ... Is it safe to say the computer is pretty accurate?
Driving conditions affect it as well. Last night, while driving under 70 mph into the wind the computer said I was getting around 23 mpg. Driving the opposite direction on the same road 20 minutes later, with the wind at my back, the computer said 33-34. Fozzy sits up high and isn't the most aerodynamic of vehicles.Driving habits play a big part in this equation.
Reading about 21-22.5 mph mostly city…. Just got it a week or 2 ago. Not sure if previous owners used premium or not. But I’m getting it tuned up and serviced at the end of the month so I’ll see if they can remedy the fuel consumption with new filters and whatever else they do at the 60k serviceYou've got a turbo so measure in smiles per gallon not miles per gallon. 😄
But what's your dash say the average mpg is? Driving behavior plays a big part and I don't think the turbo models are supposed to use 87. If you happen to be in CA note that our gas sucks, burns cleaner and burns faster. When I do road trips I get 10-15% better fuel economy out of state.
