### ⭐⭐⭐⭐⭐ 







  
  
    Works great!
  

*by S***N on Reviewed in the United States on June 29, 2020*

My car is a 2015 Camry with 40K miles on it. The mileage went up about 8% after running a tank of treated gas.

    FSM is good stuff
  

*by C***R on Reviewed in the United States on March 14, 2015*

I listen to the NW Auto show and the host, Tom Turner, believes highly in this product.  I trust his judgement in these things and bought the FSM.It is reasonably priced and I think it keeps things well maintained.  Tom and his partner, Russ, answered a question on their radio program one morning about how much fuel should be in the tank when adding the full bottle.  I believe they said 10-20 gallons.  I had the same question and I wish they would show this on the bottle.

### ⭐⭐⭐⭐ 







  
  
    Seems to be a good product.
  

*by C***A on Reviewed in the United States on March 27, 2017*

Seems to be a good product ... time will tell, but I've not detected any downside from this  and a cleaner fuel system is always a "good thing" ... I bought it because I heard about it on a weekend radio "auto show".  Based on present results with vehicle #1,  I'll probably order for my 2nd vehicle as well ...
