Gas mileage

[ZoMojave]

Getting 2-3 mpg less now that it got cold. Was getting 18 in town, now 16. A little less on the highway. BTW, mainly flat land in town. Any idea why in cold weather?

Cold air is more dense than warm air creating more wind resistance. The Winter-blend fuel also works against mileage.

Yep like mentioned cold air and winter blend gas makes your MPGs take a hit but 2-3 mpg is more than I've seen. I take about a .5 mpg hit around my area and it's not flat. Have you changed your driving habits?

I lost almost exactly 2 mpg overnight.

I drive the same route, 45 miles, each way to work. Same speed (cruise set at 72 mph) on the highway, and over the course of my entire gas tank worth of driving I dropped from the low/mid 18s down to the low/mid 16s.

I managed to squeak out 19 mpg last week when my had my cruise set at 65 mph for about 65 miles. My hand calculations are always within 0.2-0.5mpg of my dash computer

How much of a temp swing did you have. We are around 50° to 70° here in NC right now but at the worst parts of Winter I only see about a half mpg drop. Never been under 16.7 and that's on 37's.

When I first saw the drop we went from 60's to 50's which is roughly when they swap to winter blend gas at most gas stations I believe.

Now I'm doing most of my driving in the 35-45* range.

I'm also driving over 85 miles a day at 72-74 mph, which might by atypical of most Gladiator drivers so those numbers may be skewed.

Over summer I did a lot of trips around the central part of WI, with speeds under 65, mostly flat land, and consistently saw over 21 mpg

I averaged 22.2 mpg on a 100 mile highway drive (70-80 mph where possible) with local roads to the house at one end and the mountain road to the cabin at the other. Local roads around home I'm averaging around 18. This is a base Sport with stock tires, no tonneau, just over 1000 miles on the odometer so far.

Never but you can dream. ???????

No dream…. Took the pic yesterday; that’s my running average since taking delivery of my (diesel) gladiator.

Of course to be fare, I live in flatland Florida and don’t have many hills to climb, it’s not snowing and we are in a rural area where there’s not many stop lights.

Ok, if it makes you feel good then that's some seriously good gas mileage and 2 miles per gallon more than the factory rating somehow but OK!

I feel like you’re calling me a liar! I’m sorry if I got better gas mileage than you did
