C. If your car is running great why would risk a $35K+ investment to try out some nickle-nighty-eight additive?
To keep it running that way. I want to clean intake and stabilize fuel while it sits this winter.
I have not used it in my Mustang yet, but will before putting it away for winter (8oz in full tank). But I did use in my Kohler powered John Deere mower with 200 hours and it took the valve tick out completely that it had when cold, also did wonders for my chainsaw!
