Oil question

[Npd15]

Hello, I got a 2023 Chevy 2500 Custom (6.6 gas). My question is I’m tired of having dealership do my oil when I’m more than capable. I love Amsoil on my old diesels but unsure what you all think? I get a discount from them so cost is fine and also what filter? Amsoil on that also? 
 

I’ve read alot about catch cans on these motors? I had one on my old Cummins but I’m failing to see why on these? Should I add that to my list also? I’m at 11k miles

Amsoil is fine for oil.  5w30 in the 6.6 gas.  OE, XL or Signature series, all great options.

 

Filter, AC Delco UPF-63R or Wix WL10255 or WL10255XP are great options.  

 

Catch cans.  I never ran one on my 2018 5.3.  The idea on gas engines though is carbon buildup because these are direct injection.  No fuel to wash the back of the valves/intake ports.  I've seen many engines opened without a can that looked good, but also some that didn't.  Those that didn't seemed to either have long oil change intervals with lower end oils, or were driven very pampered and never got a good ring seal.

The catch can on my 2020 6.2 catches a lot of crap that would go through my system otherwise, and the cost is negligible IMO, Firm believer given the cost of trucks these days
