  1. 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?

  2. Thanks for all the info. Sent from my SM-G892A using Tapatalk
  3. 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?
  4. 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.
  5. 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
  6. 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
  7. 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
  8. 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).
  9. Do you have short bed crew cab? Sent from my SM-G892A using Tapatalk
  10. Yes, gas motor. Looks like about 1200lb difference between duramax and gasser. Sent from my SM-G892A using Tapatalk
  11. Just for reference, I've got a 2020 Silverado 2500 4wd crew standard bed LT and sticker shows curb weight at 7,110 lbs. Sent from my SM-G892A using Tapatalk
  12. This was exactly me. I hated the new chevys. I had a GMC on order. GMC took forever to come in so I bought a Silverado. Now I much prefer the Chevy look. I will say that there are very few pictures of the silverado that are flattering. But in person....it's mean looking! Sent from my SM-G892A using Tapatalk
  13. I don't think anybody would claim a 2mpg boost. I was just saying it would take 2mpg to make the $ per mile the same. If there's no other real advantage...I guess that answers my question. Sent from my SM-G892A using Tapatalk
  14. Any benefit for running 93 octane in the new 6.6? About $0.55 difference between 87 and 93. 2mpg boost would make the $per mile the same. But, I feel like a 2mpg boost is ambitious. Sent from my SM-G892A using Tapatalk
  15. ordered my sle ccsb 4wd gasser on 4/22. tpw was 9/16. I found a silverado on a lot that i liked and bought it last week. Got tired of waiting.
