  1. My 2015 Silverado 1500 4x4 LT Z71, 5.3, 6 speed, 3.42 axle crew cab, runs flawlessly on 87 octane Top Tier fuel. I have tried 89 with no change in performance or mileage. Note: I am using a Range and an Elite catch can. I had no issues before making these changes. I do a CRC GDI intake cleaning every 10 k miles also. I now have 45k miles and use no oil between 5000 oil changes (Mobil 1 0W20 ) I wonder why others are having issues with a 5.3 and 87?
  2. December 7, 2019 - I still have not seen a single one on the road in Oregon. Dave, Portland
  3. I live in Portland, Oregon and have yet to see a 4500, 5500 or 6500 truck. Dropping the mediums in 2009 was one of GM's stupidest moves ever. I think dealers and former customers are still pissed off and are going to continue buying Fords. Dave, a long time GM customer
  4. The fog lights on my 2015 Silverado LT Z71 are basically, worthless even after converting them to LED bulbs. My headlights were really bad until I converted them to LEDS. The LED low beam headlights work better in the fog than the fog lights. Before spending the money for fog lights, I recommend you drive a fog light equipped truck and see if you think it is worth it.



  5. I tried NAPA Adaptive One pads on my 2015 Silverado Z71 and they put out a lot of dust on my wheels. I took them back to NAPA. I now have Akebono Proact ceramic pads. No dust, quiet, smooth. Akebono is an oem GM supplier made in the USA. The Adaptive Ones were made in China. (The Adaptive Ones on my Buick Lucerne have not had a dust issue)
  6. I once installed Bilsteins on a 3500 van and the ride was the roughest of just about any Chevy I have ever driven over the last 50 years. I know many people on this web sight seem to love them, but they don't guarantee the ride. I installed KYB Gas Adjust both front and rear on my 2015 Silverado 1500 Z71. The ride is a little firm, but it has good handling. ,
  7. I have a 2015 Silverado LT Z71 with 5.3 engine and 6 speed trans. I have been using a Range purchased directly from the manufacturer. My mileage has only slightly dropped and it performs flawlessly. I remove it when I go to the dealer and removed it 30 minutes before I got my state emissions test. The monthly On Star report has never detected it. I would not hesitate to recommed it.
  8. I never used commercial car washes until a friend talked me into trying the Cady Car Washes in Portland, Oregon. I don't know how many states that they cover, but they are brushless and never have scratched my black Sierra. Hand washing a truck in the winter when you are 70 years old is not fun. I hand wash my 1962 Impala SS with Meguires Car Wash.
  9. 2015 Silverado 5.3, 6 speed: I had a miss fire at full throttle just before shift from 1st to 2nd. I ran a can of CRC GDI intake cleaner through my PCV hose into intake manifold per their instructions. No more miss fire.
  10. 2015, 5.3, 6 speed, 4wd. I bought the Range directly from the manufacturer with the current, at the time software, it works perfectly with no side effects. Dave
  11. Is anyone else seeing Chinese hieroglyphics on posts? Is this legitimate or am I being hacked? Dave
  12. I have read on this forum that some guys are having paint issues, where were these assembled? My 2015 1500 4x4 crew cab LT Z71 was assembled in Flint in May 2015. The quality control is excellent and my paint looks like the day it was built, without a single rock chip (38,000 mi.). The color is Brownstone Metallic. Dave
  13. My factory LSA Goodyears (2015) were about 40% at 35k miles and had terrible traction in the rain. I installed Michelin Defenders and now have excellent traction and a quiet ride.
  14. I have a 2015 crew cab 1500 4wd LT Z71 with 5.3, 6L80E, 3.42 gears and tlr package. The 9200 lb tow rating was probably based on driving on a flat highway. I towed a 6000 lb car tlr across the Sierras with it. It was OK, but I really had to gear down on the mountain passes. I never overheated. If I was going to tow your 7500 lb trailer, I would definitely go for the 6.2 ff you drive over mountain passes. The 5.3 with the standard 3.08 axle would be terrible towing in the mountains. Chevrolets tow ratings are exaggerated. I hope this helps. Dave
  15. What does this have to do with GM trucks? Which do you prefer, Budweiser or Miller beer?
