Gumout® One-N-Done Complete Fuel System Cleaner is specially formulated with advanced P.E.A. technology for unsurpassed cleaning strength. It is designed to be a once-per-year treatment that improves performance & fuel economy and helps reduce emissions in just one use. Compare that to using products that require repeated usage every fill up or 3000 miles and you will find that One-N-Done offers the most complete fuel system cleaning at the best value.

Polyetheramine, or P.E.A. for short, is the most advanced cleaning agent available. It is strong enough to cut through thick carbon deposits even in the intense heat found in the combustion chamber.

I used this in my 2007 Ford F-250 with a 5.4L V8. It did everything as advertised and more. Wow!

I used this product in a car from the year 2001 with 250,000 miles. My car did not have any issues to begin with but because there was a rebate for the purchase price which made it free so I figured I would give it a try. I have no way of knowing what it really did so I am going to have to trust them on this one. What I can say is that it did not cause any issues with a old car and I did get my rebate. In terms of ingredients this fuel cleaner contains Polyetheramine, or P.E.A. which just like they say is the best cleaner out there at the moment. All in all it is hard to say if I would pay full price for this product unless I was having serious issues. I think for the average folk out there $25 is a good amount of money.
