2019 Ram 1500 Classic 3.6L Fuel Economy

jeeperrob_k3rob · Mar 30, 2024

So im not complaining but ive noticed Im not getting anywhere near the fuel economy numbers im suppose to get with my Ram 1500 3.6L. What are you guys getting for fuel mileage with the 1500 classic 3.6L 3.21 rears? Im averaging 19.1mpg on the highway.

Combined highway/city I average 18mpg but city for me is suburbs. Highway I average 20-21 mpg at 65mph and above. Straight city I have no idea because I just don’t do too much downtown driving. I have a 2018 with 3:21 gears and a 2 inch front end level with LT275/65R20 tires.

Ok. I might need to get on a longer highway trip to really see the difference.

Plus I will be getting a roll up tonneau cover as well. I dislike tri folds!

One thing to note is with our 3.6 and 3:21 gears highway speeds much over 65mph will bump the transmission down to 7th gear from wind resistance, drag and lack of torque. If you have the steering wheel control for gear selection put it on 8th gear and watch it drop as speed over 60-65mph increases even on a level highway. To effectively use 8th gear I pretty much have to stay under 60mph and I do get noticeably better gas mileage keeping it in 8th gear.
