[/b] :D Hi! I wanted to ask - Would it be okay to use Marvel Mystery Oil along with 5W-30 Mobil 1 Extended Performance Oil (Fully Synthetic) in my Dad's '98 Silverado without causing any harm?

Marvel Mystery Oil was used in the day of leaded fuel and carburators to help remove soem of the generated contaminents. I see no reason because of modern electronics, fuels and oils. It won't hurt but is a waste of money.
