If its pinging then yes it will help with that. But if it runs fine and no ping just putting race gas in will do nothing. It will allow you to make adjustments to get more power such as advancing the timing but just putting race gas in the tank will not give it more power. You would have to make adjustments but when you go back to pump you will have to change it back. And in cold weather race gas is much harder to start the car on. Ron
