I liked mine but the interior space and materials kind of grew to be annoying and I never got the killer milage some do. The DPF system probably hobbled an otherwise decent little truck. Now the EPA is cracking the whip on mods to add insult to injury. In addition, the future of 2.8 is up in the air last I heard. Edit: The 2.8L Duramax engine will be produced at the GM Flint Engine plant in Flint, Michigan, USA. per GM Authority.I don’t see fuel mileage being any issue with Rotell a or Delvac. The issue will be a plugged up DPF
if the new 3.0L can run on water thin 0-20 and survive then our trucks running on 5-30 or 5-40 should be better off.
I run Amsoil 5-30 full saps, signature series diesel oil. I am not deleted. But I vent to atmosphere. I don’t want any of the oil mist to make it to the DPF.
I also think these trucks soot up the oil really badly. So I change the oil every 3-4K
I also run Hot Shots secret at every fill up.
Todays oil life monitors are not setup to be good to the motor but better for your wallet and the environment at the expense of engine life.
Time will tell if i am wasting my money or not.
I have owned a lot of vehicles over the years and none of them have lived up to the fuel mileage hype.
Until this Colorado
This truck is very impressive. It’s the best vehicle I have owned so far. Spooky with all these issues on the forums for sure.
when you consider how small a 2.8L engine is, impressive is an understatement....
