Good to See. just flipped 105k on my 2016. replaced a turbo and coolant line. other than that, just normal wear parts.
really enjoy it's towing and fuel economy. was the timing belt Dealer performed? and would you share a ballpark cost?

Nice to hear others not having any issues. My 2016 Canyon shot a rod at 72k. Hoping the new engine goes that long with no issues. So far so good with 10k on the new engine. Other than new engine no other issues with 80k on the clock. :)

80-90k the particulate filter went hopefully yours goes longer.
Worst part was it is specifically written out of the warranty

pbennett,

Could you please share your truck maintenance routine and habits that got you over the 200,000 mile mark?

1) How often transmission flush?

2) Any DPF or emissions related problems?

3) What oil change intervals? What motor oil - Dealer supplied 5W30 Dexos2, Mobil 1 ESP 5W30 or something else?

4) What part of the country do you live, and what percentage of your driving is city driving?

After reading about some other owners with lesser miles, suffering with broken wrist pins and blown pistons (through the block) - using the dealer’s oil, it would be interesting to know what really works

Good questions. My only adds. Any tunes? (I checked older comments, but might have missed this). Any idea of your driving fraction under "heavy" loads? Any spectroscopic oil analysis? If so, what did you find?

Sorry for the Delay.
I had no tunes change oil at 5000 intervals
Believe it or not I have not changed trannie fluids I only used Mobil 1 full synthetic 10 40 as of late
Towed very heavy 10000 at least 40000 miles

Appreciate your complete replies. Thanks.

One follow up. Why did you go with the more viscous oil as of late. We're you starting to burn some?

This engine really doesn’t burn a drop
Just felt with engine wear and the heavy tow load ,with the higher mileage I decided to use the heavier oils

Been using T6 5/40 for most of my truck's life. The last oil change I used T6 and as the current change came up, I noticed I used a gallon of 5/40 and 2 quarts of the 15/40. The bottles a both blue and look nearly identical, and I did not notice the different weights at the time. Over the 7.5K mile interval it only used 1 quart, which is less than it usually does. Got another bottle of T6 5/40 and used the rest of the 15/40 this time around. My 2.8 seems to like the "7.5/40" blend.

It is worth noting the older 2.8s specified 15/40. I suspect the main driver for GM specifying 5/30 is fuel economy. I know I would be nervous about running the specified 0/20 for the new 3.0 diesel.

Me too on the 0/20. I see this just like the BS charging algorithm and it's expense on batteries. It's all a kick the can down the road and hopefully the warranty will expire before things start go south.
