I'd like some feedback from Amsoil OE users. Any reports on engine cleanliness inside when doing engine work? Usually I like to run their Signature line but have really been liking their OE line since I started using it on my DI Subaru 2.5 on short 3k OCI a year ago and UOA was good. Recently acquired a 2024 GMC 1500 with a 5.3 and will go with OE for a while during warranty following the OLM. Maybe I'll upgrade to Signature for extended 10-12k OCI if possible down the road. Buying a 1 gallon 4 pack OE 0w-20 brings it down to $6.94 before tax with free shipping with P.C membership. I'm not really comparing the oil to other off the shelf choices. I personally think it's priced competitively and I really enjoy and trust Amsoil products/ performance. So I'm sticking with OE even if it's not their flagship oil. Feel free to comment your experiences whether it's positive or negative about Amsoil OE.
