I got 25.2 on my first full tank after buying this off-lease '21 with 2WD. The computer nearly-accurately showed 25.5. This is right on the EPA combined rating of 25. This is suburban driving; lots of short trips in the city where I pay close attention to the EV Coach to keep it in electric mode as much as practical. I routinely get 27-28 on those short trips. Plus maybe 30% highway miles at ~72 mph. I'm driving it with a fairly light touch but I'm not the slowest one out there by any means. When I bought the truck the long-term computer calculation was a little over 22 mpg.

Filled up the truck on the 31st. The truck Trip 1 read 353.7 miles, 72.5 electric miles, and 21.5 mpg. The hand calculated mpg was 20.8.

I had been averaging 22.6 over the last 12k+ miles. 3 weeks ago I installed new wheels and tires (Both wheels and tires are the exact same as before only brand new) and discount informed me of a broken axle bolt. I took the truck directly to my dealership And they replaced axles. As soon as picked the truck up from dealership I immediately noticed my fuel economy droppin. In my normal driving situation (home to office for instanc) what I would usually expect 22-24 mpg on a trip, I am now getting 18.5ish. I can only think of tire pressure or winter fuel as new variables.

any thoughts?

Could be due to the differential lube they refilled the rear with. If they used a heavier oil or non synthetic, it can create a loss.

Best of knowledge, when they replace axles in these trucks they don’t have to drain fluid?

I would think so, nothing else to remove or check for debris in the fluid. With the axle out, they are certainly going to lose a little bit of fluid.

Would have to check the service record and see if a shop simply added fluid or if they drained and refilled.

Are your tire pressures different than what you were running three weeks ago?

Added about 3 pounds this morning to see if that changes anything
