1 Gallon Ethos Fuel Additive

Ethos Fuel Reformulator 16 oz Ethos FR

I have used Ethos fr for about 4 months now in a 2003 Mustang and a 73 MG B-GT and have noticed a couple of things: First, the MG is running much smoother and starts as if I just rebuilt the engine (never been rebuilt), but I don't know about the mileage. Second, I have noticed a difference in power and mileage in the Mustang. I did use 4oz in the first two tank fulls and 1oz for each 5gal, not 10. Idling for the Mustang has also changed. From about 900rpm to less than 7 and never rough

Unfortunately I have seen no improvent in my mpg, and I am currently on my fifth tank with Ethos added. I also added some to my crankcase oil as recommended. On the other hand, my vehicle does seem to be running smoother and quieter, although I have no way to directly measure this. I won't be buying anymore.

This is the first time I've tried Ethos and so I give a diffenent yes to the fact that this product is working. Plus, I don't have a way to test my fuel emissions without paying my local car dealer a hugh amount of cash. However, I can say that this stuff has made my 2001 Buick Regal run a lot (and I mean a lot) more quieter -- it's almost like I'v driving an electric car. As far as my diesel truck, it appears that my gas milage has imporoved to about 2 miloes per qal. thus far per mile. Needless to say, Ethos looks promising.
