Advance Autoparts has the Gum Out complete fuel system cleaner regularly priced @ $6.50 at 75% off, which is $1.66. What a bargain! If you are interested you can stock up. Check your local store. This is not the fuel injector cleaner, but the entire system cleaner. Gumout is made by Pennzoil (Shell Oil Company, F1 Ferrari sponsor), a reputable manufacturer.
