and the same part number except for the added first # for the Wix filter....WIX 56116 is a rebadged NAPA Gold 6116.
So curious me just asked the Napa parts desk, and they were positive all their filters were made by wix. Now I know the employees aren't usually very knowledgeable in most stores. However, I've never had that problem with Napa... I'll have to dig a little deeper into this, I'm getting that conspiracy feeling...
I was watching a episode of engine masters on motortrend and they were using a oil that is good for 100k miles between changes. Going to have to remember watch it but think it was made by amsoil. If that's possible I wouldn't trust anything over 10k between oil changes.
Remember, it's gotta be dexos approved! Lol
