Just purchased a few cases of Castrol Edge EP. I’ve never used Castrol before. However, as far as I can tell it’s the highest rated Dexos Gen 3 oil out there. Seems like a Euro version of 0W20 with Dexos rating. I’ll be changing out my oil soon on my 2024 GMC Sierra 5.3 with it. It’s currently running M1 EP 0w-20. I want to stick with Dexos rating for warranty purposes. It will go into the 2021 Subaru Outback 2.5L eventually too. I’m particularly interested in Fuel dilution and intake valve deposits performance. Seems like Walmart no longer carries it. I was able to grab 6 QT cases off of Amazon with Subscription for a reasonable price.
