I have allways liked Valvoline oil I got on sale at Advanced auto parts.

Valvoline Premium Blue...
I noticed in AutoZone the other day that Cummins endorses it and recommends it for their engines.
That's a strong statement about something. I don't know too many people driving diesels and into technology/mechanical things who don't have a high regard for Cummin's diesel engines.
I wonder what that stuff is like.
