I forgot about the winter formulation in some areas.
Yep. In general I think given cold temps, new motor (and ecu still learning), different tires -- his mpg is normal. Also even light wind is a large factor, even in the city, and sometimes it's kind of hard to tell when it's happening. My mileage started out the first 1k miles pretty crappy and then started getting better from there, but I think it was more because my ECU started figuring out my driving habits and the shift points became more optimal.I forgot about the winter formulation in some areas.
We deleted the stock tires and had them put on Blizzaks instead, but they put a 30" tire by mistake (so in theory my milage should be BETTER). They looked small right away, but I assumed it was just because where I live you don't see Jeeps with stock tires... But I digress. We figured it out pretty quickly (actually, when we checked the pressure) and have decided to switch to 33" KO2's right away instead of buying new winters now and the KO2's in 2-3 months. I need a tire for compact snow and ice, so we will rebuy the Blizzaks next winter instead, and I'll just go easy with the KO2's in the city. They will be installed sometime this week, so I know my milage is going to drop quite a bit.
My biggest mileage differences came as my vehicle learned my driving habits and the shift points became more optimal. You might lose a single mpg, at most. BTW, you are hand calculating your mpg, yes? EVIC is pretty consistently off, especially if you didn't reflash for the tire size.
I only have one tank to calculate as I'm on my second tank, so no hand calculating. I do have an app though that says 14.2 l/100 km (my converter app says (16.5 mpg) but the first 100+ kms (1/5th of the tank) was straight highway driving. This tank is ALL city driving. And yes, I'm driving like a granny (LOL). I've told my husband that once spring comes around (and I start doing my usual out of town adventures) that I expect the milage to go down and not up. I'm only half joking, but that turbo is so. much. fun. And Cindy Lauper knows I need to do. lol But for now my foot is light... it's good to know it might only drop by 1 or so mpg! I thought it would be much worse.
That’s right. So based on all these variables, 15(ish) mpg doesn’t seem low to you too?
At first glance it still seems low but with newer vehicles being so sensitive operating outside designed parameters, I’m not confident in what to think. Comparing would be easier if it were stock and another stock and local Jeep using winter fuel would chime in.
My 2.0L really picked up mpg around 4000 miles after 1st oil change.
Good to know! I figure it's just a result of all the things mentioned (snow, lots of stop/go, hills, etc), and of course that whole engine break in thing. I'll wait it out another few thousand kms. It will change a LOT in the spring too, for sure. Winters I ski and snowshoe, but the ski hill is only a 15 minute drive from my house. In the spring (like the day after the ice melts) I'm on the lake. Any lake. We're surrounded by them (lots of highway driving).
