Ok here goes
I use my truck to commute to work 37 miles each way on relatively flat two lane highway never breaking 60 mph. I work 3 on 4 off 4 on 3 off.
I hand calculate each fillup and have typically seen 22-24 mpg. I have a crew short 4x4 3.55 with the 275/65/20 toyo at. And I calculate the difference in tire size as well
When its all said and done my hand calculations come out very close to what the trip meter says. Close enough that I believe the instant read to be fairly accurate which is where my questions comes from
I recently started driving and not letting it shift into 8th gear as I tried it a few times for kicks and I ultimately feel as though it was often lugging when it would go into 8th and I also figured that 7th gear with my taller tires at those speeds couldn't be a whole lot different than a 3.92 truck in 8th gear. Low and behold I see much more consistent 26-31 mpg readings on the instant read where before I would see 22-25 plus its less shifting on the trans. So I can only assume that when I am on that same stretch of highway and my instant read is 21-22 I am in a regen?? And this adds up to where I could or would see this about every other trip to work about every 80 miles
Does any of this make sense?
I am totally onboard with getting a GDE but I like many others are still waiting out the EPA situation. I guess I am just trying to understand my truck a little bit more is all thanks for any incoming information
