I run Stanadyne Performance Formula additive in my truck every 2 or 3 tanks. I've bought 2 cases of 12 16oz. bottles. The first I picked up from a shop in Augusta. The second I ordered online but don't remember from where. I'm on my last bottle so either need to find a supplier or switch to something else.
So, what does everyone use? How often? And do you think it actually makes a difference? I started using this after the mechanic who replaced the CP3 and FPR in my truck recommended it.
