Or is the price the best gauge?
No flames please...a decision was reached on the OLM deal & it will be changed at 50% from now on per the owners wishes.
thanks guys
Id say its a toss up, and comes down to price. the nice thing about the blends, is that usually their cold properties are slightly better. Although, Pennzoil conventional is close in a 5w30 at -39 which is excellent.
