The last time I saw this subject come up, I offered a free sample of AMSOIL's PI fuel additive to the first two people that contacted me. Seeing this come up again, I had to get permission to post some feedback. If I get permission from the other individual I'll post it here, but for now, Joseph Guerra (currently forget his TS username) said:

I did use it in my New 02 Camry v6 SE (w/ 5,000 miles on it). Never before had I gotten even close to the freeway rating of 28 mpg, even thou I have taken it on many trips. I used it before going to the coast, On this trip we got over 29 mpg! 452 miles on 15.4 gal of gas! And it was not even all freeway miles, but rather it was about a 75/25 mix of highway and city! Also I don't recall the engine running so smooth or as good as it did on that trip. My overall impression of the Amsoil PI is I don't believe it , so im going to order another bottle or 2 soon. To see if this was a fluke or not.
Thanks again for the opportunity to try this wonderful product,
Joseph

And my personal experience on my 2002 Tundra was that my mileage improved from approx. 14.6 to approx. 15.4, and a noticeably smoother running engine...
FWIW, this product is used at a ratio of 1 ounce to 10 gallons of fuel following an initial 6 ounce treatment. Because my truck was so new, I opted not to perform the shock treatment and still got excellent results. It is very cost-effective, as fuel treatments/injector cleaners go...
