    My 2019 is getting 850 miles per gallon give or take yours seems pretty steep indeed. Gm should tell what the milage should be relative to the fuel burn... Maybe a call to corporate or another dealer

    I just paid 1.45 for diesel and gas was 1.89 I feel like I was stealing ... Mora mn is having some sorta diesel war and I am enjoying it filling my truck up for less than $50 you can't go wrong with a diesel and I got 24.2 mpg on a 50 span going 65 unloaded whooot whhhot but 11 hauling the 9k toy hauler. My calculated mpg has been 20.2 unloaded for 2 tanks combined driving. My regens are at 820 miles so I passed on the update, my shortest Regen was 500 miles with idling and winter fuel

    an expense... the more you spend the more expensive it is... it will be worthless in 20 years... ouch... no worries though there is no inflation... oh wait...

    Napa synthetic is fine or mobil1 or any that meet the requirements. Dexos required? If so make sure it has the dexos logo

    I used dexos oil in my gas 6.2 changed it early and still lost a lifter at 59k cyl 4 afm cylinder. I contend faulty design The dealer sold one and with 23 miles on it it did the same thing as mine. Some poor other person got a brand new lifter and that was on a 2018. You have to change the oil in a diesel whether conv oil or synthetic at the recommended interval, there is no extended drain interval in any reading from any manufacturer I have seen.

    If you're in the snowbelt bilstiens if south then the adjustable ranchos. I guess so cal is south enough to withe ranchos I have had both the adjustables are nice.

    Mine does it in exactly 20 miles if kept above 40 mph

    A call to gm customer service is probably in order or have another dealer or this dealer reflash it

    It will also run higher idle when Regen is active iirc on mine it is right around 800-900 rpm . Make sure it completed a Regen.

    RF all 4 tires... this seems to be an issue with the tires everytime they get rotated they cause vibrations... Why who knows why ? it is just plain weird... happened to me... even moving from front to rear the vibe stuck around... after they RF'd all 4 tires again then it was good as gold... even the SM was in disbelief that it worked...

    well it has been a while sense I posted up. So as a follow up so far about 1000 miles sense they fixed it, it is still fixed. I was over 80 this weekend.. and I was shocked when I looked down.. I really thought I was only going 65 or so... so lucky for me I am all fixed.. I am heading to Utah for a 4wheelin' trip so for sure will get to put on a boatload more highway miles... I still have the crappy LS/2's on it but so far so good... I hope they can figure out how to fixe the rest of these that are broke... 3 tires, 1 new rearend, RF balanced to less then 10lbs per tire.. i think the threshold is 16 or 15.. but mine vibrated at that balance...

    this has the same clutch system as my 4wheeler..

    did they have a pico computer? if so did they put it on? if not then you won't get far fast... I know i repeat myself but it worked for me... that got my rearend fixed and then all the tires below 6lbs of RF... and it is now my smoothest vehicle I own.

    then go to the service manager... see if that helps... if not then open a ticket with corporate try those first in order... don't be an arse... just explain and be level headed... let them tell you no... then when you open the call with corporate let them know... they can arrange a different dealer... To bad you aren't in MN I would recommend a place to go

    you need to make them put the Pico device on it... with the NEW software that is available... it will tell them exactly what is wrong.. if they don't have a Pico device then don't do business with them.... Of course this should not be... but it is what it is.... All I can say is it worked for me and I am now a happy customer... But I had exceptional service ....
