Seems that our Gen 5 trucks are especially sensitive to the cold weather; past winters I've noticed a drop in mileage but would improve as the weather warmed up, even one day to the next and it was real easy to bounce back to the regular 19.2. But this winter seems to be different I'm off by about 3.6 mpg and it tough to get back to the standard 19.2. Anyone else have similar experiences..........

 

I have definitely noticed a difference in mileage per tank. I try not to rely on the dash calculation just go off how many miles I get per tank. I attributed it mostly to remote start and letting it idle 10+ min to warm up the inside before work pretty much every morning.

 

The warm up time will kill your gas mileage. Newer hybrids they tell you just to start and drive, i assume that's to keep MPGs up

 

My econ went from 15-17 down to 11-12






but I also lost overdrive in the 4L60 😂

 

Actual range is reduced, confirmed by dash readout. I've stopped the auto start warmup and that's helped a bit. Wondering if they're oxygenating the gas really good this season..........

 

I'm getting 7mpg, lots of remote starts and being -10 to -20+ at night makes for poor mileage.

 

Colder air also burns more fuel, and makes more power.

 

Good Lord -20? Everybody is flipping out around here because its getting to 0 Sunday or Monday night. Business is good though.

 

It ain’t supposed to be 0 in central Texas.

 

I'm not even that close to Canada, that's still 5-6 hours north and it's that cold. Been a over a week straight of well below zero, didn't even hit zero degrees today.

Sunday into monday will be -20 to -25 degrees where I am. Windchill around -40.

Ely, Minnesota hit -50 this morning.
