If your going based upon cost and they are close to the same, and have been running dino's all along then just do it. Pick the MC or T/A in your favorite weight and give it a whirl, you don't have anything to lose it's only a oil change. Who knows you might even be happy with it
. Besides if cost is a factor, then Shucks has Shell for 49 cents and Valvoline for 79 this week
