I use the Oreilly brand 10w30. It's made by Valvoline. I also use Rislone ZDDP additive. I mix it together in a five gallon bucket before I dump it in. It's what I can afford so it's what I use.
This surprises me. I could swear it was you who said additives don't mix and I believe it. The oil will just be what it is. 10w30 0r the additive. That's what the engine sees .
