I have a 2015 Silverado with the 5.3 EcoTec and I have been using the dealer oil but they have changed my oil for the last time and I have been thinking about getting the AC stuff and doing it myself with a Wix XP filter, they have been putting a AC E-core filter on it,. I am having a hard time deciding on what oil I want to use. I am interested in NOACK burn off but I run a Elite engineering catch can. I want to use the Pennzoil Ultra but it can be hard to find, I also like Valvoline Synpower and used it for years but it does not use Moly it seems.
I have thought about just using the AC Delco stuff but wanted to hear from guys that have used it long term. Thanks guys
