The gas treatments are sh!t. I had a hopped up Mustang that ran great. I stopped at a Speedway (haha) and got gas. About an hour later the car died on me at speed while going around a curve at 60mph. Tried turning it over a few times and after a few minutes it finally started up and ran fine. Couple days later, same thing. I tried to figure it out by changing some of the electronic stuff, plugs, etc. Problem kinda went away and came back at random. Took it to a shop. They drove it back and forth to work for 3 days and couldn't get it to fail. Finally after a year of messing with it and the car mostly sitting because it kept stranding me everywhere, I got fed up and sold the car. The guy that bought it decided to try putting a new fuel pump in it. When he drained the tank it had almost 3 gallons of water in it.
