Poor Fuel Economy

I’ve had a ‘22 SEL about a year now and the mileage is definitely nothing to brag about. It takes a further dump on winter gas, for whatever reason. You can sense the changeover and see it in the mileage. My average, with no change in commute, has dropped from 25.5 to 23.5 just with the change in season and gas.

My mileage is a 60/40 combination of highway and city. I don’t get it. Either Mitsubishi or Nissan I’m sure has engines sitting on the shelf that could get similar mileage with more power and torque.

So, yeah… this is normal.

Okay first to determine fuel economy manually which is most accurate. Reset trip to 0 then Fill the tank, then drive normally for the tank or at least half the tank. Fill tank and note the trip milage and the gallons it took to fill the tank and divide the two for true miles per gallon calculation.

Do this and you will see your accurate mpg.

2022 AWD commute gets 23 mpg. This is Texas so traffic is going 80. 🤷‍♂️

I have a 2022 Outlander AWD with about 8000 miles on it and lately I have been getting 19 MPG on local driving and around 350 on highway with a full tank of gas. Not sure if the cold weather has anything to do with this, but driving around at 25mph in auto mode, I have noticed that it goes into 2nd gear and the tach would read 2100 rpm. Like it was stuck there and wouldn't shift into a higher gear to bring the rpm down.Has anyone experienced poor fuel economy with their 2022 outlander?

I noticed the same thing with the high RPMs in very cold temps. It will last for about 10 minutes then drop back to a normal idle. Only doing it in temps in the 20s.

You're right, in case le weather, RPM is at 2500 at 50km/hre and it should be around 1200. I'm in Quebec so it's cold. If you change in manual mode, you see you are in 3nd speed. You can remediate by shifting manually to 5 or 6nd speed for few minutes until the motor and/or transmission are at higher temperature. Mitsubishi know the problem but I don't have any news about it. I will call the dealer this week. It sure it affect gas mileage for people's that make shorts distances in cold weather. The mysterious thing is that my Outlander sleep in a heated garage, so the engine is not cold. When I go, it take about one minute and the RPM increase at 2500 RPM. It look like the RPM is adjusted by exterior temperature and not by the engine temperature.

I'd like to hear the reply you get from your dealership. I got that it has to do with the oil pressure/temp and the air temperature. Watching those gauges while driving, it seems that they coinside with the high idle driving in the cold. It's annoying but I'm getting used to it. I like in Pittsburgh so cold and hilly. I'm on and off the throttle often and that pause I get when I hit the gas pedal just feels strange. I drive far enough that it stops but it's often for a good 7 to 10 minutes of the issue.
