Doctorx Injector FSM - Fuel System Maintenance Cleaner and Fuel Injector Cleaner

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

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 ... 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 ...

After a good cleaning at the Doctor Injector store this little bottle of wonder juice is keeping my fuel economy up above the factory stated numbers. I'll have to use it in all my cars now!

My husband has been using this in the gas tank of his cars for years. Put on bottle in after each oil change and it keeps the engine clean and running smoothly.

My Jeep noticeably ran smoother after using FSM. It cleaned the whole fuel system including injectors. I have used it in the past. I found the price on Amazon much lower than at dealers. Quality product.

Had this product recommended for use in our outboard motor - works great!

Do not know if it works.
