Silverado 1500 Diesel - First impressions
Just picked up a new company rig a couple weeks ago. 2023 Chevy half ton Z71 with the 3.0 Duramax. Near as I can tell it doesn’t have the max towing package (only because the brochure says max tow...

Well being the guy who generally gets low end mileage in ANY vehicle, this thing is just silly good.
Just sucked the 4th tank of diesel through it and got over 2k miles on it.
This tank was 25.4 on the readout and 26 hand calculated. If I introduce the 12V error in my ways factor, it’s still over 25mpg.
All commuting 0-90mph depending on traffic and maybe 15% city driving.
Ran the DEF down to about 50miles to empty….thanks GM. When it’s basically empty, it takes not quite 5 gal of def….whos dumb idea that was, idk. Since 99% of light truck owners buy it in 2.5 gal jugs, the only size offered…so that’s nice. It takes 4.8 gallons and then spills down the side of the truck….
Otherwise it’s flawless. Regens are quick and easy and happen even while idling and putzing around. It does an active regen every couple 3 hundred miles. (But I’m basically putzing in traffic half the time).
Mpg has gone up abiut 1/2 mpg per tank, assume breakin. I’ll be very surprised if it goes up much more.
And acceleration/power is impressive until you get above about 70mph. Full throttle pulls from freeway speeds are fine but it’s the only place the lack of HP compared to the big gassers shows up. It’ll lock up the diff and get sideways on dry pavement (tc off) from a 10-20mph roll, no problem!
