  1. LTZ trim color "slate grey" has a constraint on the builder that requires a black 18" wheel. Seems weird because there was an LTZ truck at a show in slate grey with the chrome 20s. I bet its a glitch in the builder.
  2. Yeah, I see the notes, I was just wanting to double check that this option (with one of those packages) would indeed give the LT the new front end and headlights. And not just replace the halogen with LED in the same fixtures. That seems like a really big change to a truck by adding a package. normally the appearance packages are just paint/chrome/wheels and not swapping out headlight assemblies. but, if that's what it is I'm certainly here for it.
  3. I was just looking at the order guide that was posted here. It shows the T4L as an option for the LT trim. I was curious if that was a typo, or if it just meant that the halogen bulbs would be replaced with LED in the same assembly. I'm probably just wishful thinking.
  4. So, what do you think the T4L option will do for the LT trim trucks?
  5. Do you know if the LED option (T4L) for the LT trim replaces headlights with the new style? Or does it just give LED bulbs in the same fixture? I've been an LT trim guy the last few trucks, but I really like the new front end. I'd love to get the new front end on an LT if possible.
  6. I'd take every mpg report with a grain of salt. I logged my mileage in fuelly for dozens of tanks. Mpg was consistently less than the dic said. Most people report their better numbers from the dic and not the actual mileage. For reference I'm stock height ccsb 4x4 and I get 11-11.6 on nearly every tank. Here's a previous thread on fuel efficiency https://r.tapatalk.com/shareLink/topic?url=https://www.gm-trucks.com/forums/topic/228093-66-gas-mpg/&share_tid=228093&share_fid=33003&share_type=t&link_source=app and you could expect a level and bigger tires to slightly affect it from there. My guess is you would get 10.5-11mpg Sent from my SM-G892A using Tapatalk
  7. Wife is getting a new 2021 ride. In between yukon slt, tahoe lt, tahoe premier. Is the magnetic damper ride significantly better? Worth going for the premier? Sent from my SM-G892A using Tapatalk
  8. Posting an update with a few more fill-ups. Truck is daily driver. 80% highway 20% urban. I hook up a 24ft livestock trailer or a 35ft flat deck about 2-3 times per month. My DIC is consistently 1-2 mpg higher than the real mileage and my "best avg" numbers are way higher than anything I've ever gotten on a tank. Anybody else using fuelly care to share?

  9. Thanks for all the info. Sent from my SM-G892A using Tapatalk
  10. I'm about to change my oil for the first time. Book says 8 quarts of 5w-30 synthetic. What brand of oil are you guys running? Is premium oil worth the extra money?
  11. Great write up. I'm going to start using fuelly. I wonder what the difference is between the trip mpg and hand calculated mileage? Does the DIC exclude fuel burned while idling? My DIC is also consistently higher than hand calculated.
  12. Good point. No, I havent been correcting for the difference in circumference. the difference between stock tires and mine is about 1.6" in circumference (1.5%) so I could adjust all of my mpg by 1.5% 12.9 mpg would go to 13.1 12.1 would be 12.3 11.9 would be 12.1
  13. I'm assuming these are from the DIC readouts? What are your distance current and best mpg's? I'm just trying to get an apples to apples to see if my slightly bigger tires are having that big of an impact. My 25 mile current is 13.4, best is 17.2 My 50 mile current is 12.8, best is 14.8 My 400 mile current is 12.1, best is 12.8 Also, I'd be interested in your hand calculated mpg once you get through a few tanks. My DIC is typically off by 0.5-1mpg
  14. I wonder what fuel mileage would look like if I kept it out of overdrive. I've noticed that it does stay at lower rpms at hwy speeds. Sent from my SM-G892A using Tapatalk
  15. Update after I've got a few more miles on my 2500 LT 4x4 crew cab gasser. I've got about 2500 miles on my truck so far. Here is the MPG from my last 3 fillups. Note, that these are all with zero trailers, and no added weight other than passengers. 12.9 MPG. This is my best tank average so far. This was 95% highway driving with cruise set for 70mph about 60% and cruise set at 60mph about 35%. There were some points where my DIC was reading 15-17mpg over a 25 mile trip. I really took it easy on this trip and kept my foot out of it to see what the best fuel mileage potential I had. 12.1 MPG This was from a mixture of about 60% highway to 40% in town. Drove normally, not heavy foot, but not babying it. 11.9MPG This was also about 60% hwy to 40% town but with a few mornings of warming the truck up, and a few times where i idled for a little bit. These are just from my last 3 fill up receipts. And, for the record my trip mpg display has been about .5-.8 mpg higher than hand calculating. I'm thinking that 90% of my tanks will be right at the 12mpg. I've got 285/65r20 ridge grapplers which are .5 inches bigger than stock, so maybe theyre causing the difference. I'm just not getting anywhere near the numbers that people are posting on here (13-14 in town, and 17 highway).
