Just wondering, what brand DEF do you all use? My truck is the 2021 3.0 so I was wondering if it matters. I know years ago GM tried to tell everyone they needed to use specific DEF or it would damage the system. Thanks
Thanks. It’s a Northsky blue metallic LT crew cab. Only had it two weeks so just getting started on making it mine. So far put in bed liner, tri fold tonneau, vent visors on windows, wheel well liners and upgraded lights to LED that Chevy decided to leave old time bulbs in.
Happy to have found a forum to go to for help and info on my 2021 3.0 Max. First time owning a diesel but have strong mechanical back ground so should be fun. Looking forward to having discussions with you all.
