Getting Good MPGS

So here goes on the interstate I run 17 and on secondary rds I run 23ish.
My 18 dcsb has a ARE cap 2.5 lift and 33” tires.
It’s been a good ride so far!

avg per tank sucks but I idle a lot

 

My 07 seemed to get a bit better fuel mileage after about 2 years. I don't keep detailed records so I can't prove it, but it sure seemed like about 1-1.5 mpg better at that point.

Running the engine at higher RPM's in many cases is actually easier on the engine and will improve fuel mileage.

 

I'm curious though, I'm wondering if this truck does better MPG if you let it rev up before shifting. Seems like lugging the engine is more inefficient.

 

Umm.. but why are you parked on the side of the road with the hood up?

 

Sport 4th unless, on the open highway and personally I never use 6th.
