  1. 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
  2. My 2019 with 12k on it and driven in mn winter looks almost new underneath you need to have a local body shop look at it and get an unbiased opinion not that it will matter but may help you in how to move forward
  3. I looks good get out the carnuba for the real shine and elbow workout. I tried the turtle Wax spray carnuba was and for in between waxes it is awesome fire up the clay bar for the bugs
  4. 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
  5. 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...
  6. Get a bed rug if you're not hauling heavy stuff
  7. Napa synthetic is fine or mobil1 or any that meet the requirements. Dexos required? If so make sure it has the dexos logo
  8. 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.
  9. 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.
  10. The used car market is going to have some smoking deals,l but not sure about the truck market and how that will pan out. Good luck just make sure you test drive anything used and get the Carfax now that will help too
  11. a diesel is not in your future here. The 6 l will run a long long time pretty bullet proof and the prices for used will be going down due to the current glut hold out another month if you can. You will come out way ahead on the gasser compared to the diesel. Change the shocks out the ride is almost the same as a 1\2 ton, lower the tire pressure to 60lbs when unladen and enjoy. And echoing the other vibration test run it to 76-80mph if it vibrates walk away and keep looking no matter what they tell you. Do a Carfax for sure
  12. I'd roll the dice for sure they will make more of them...and sooner or later will have to sell them
  13. Usually the ones that were chipped stretched the head bolts I haven't heard of anything in the l5p in this regard
  14. Mine does it in exactly 20 miles if kept above 40 mph
