Star Tron Enzyme Fuel Treatment?

That's what they all say the stuff you are talking about is just like every thing else on the market they all say the same thing. The stuff that I know works best is Chevron Tekron fuel system cleaner, that and gunk high mileage these two both do a good job of cleaning out the fuel system. What I would do is drive the car until the tank is almost empty and then go to a gas station and put in the fuel system cleaner and then put in a gallon of gas to mix up the gas a the fuel cleaner then go and drive the car hard for about ten miles then fill up the gas tank and drive the car normally.
