We live in the Northeast and during our winter months I utilize this product when the temperatures are below freezing and in the summer when temperatures are above 90 degrees Fahrenheit. This helps to prevent moisture in the fuel tank and lines of fuel.

Slightly better gas mileage and idling. MOG is good enough to pay for the bottle. So everything else is free.

Gracias a este renovador de agua pude salvar una hidrolavadora casi nueva a la que le entró agua al tanque de gasolina. Lo recomiendo al 100%

I mean its not like it will save you a fortune or anything but I notice I get about an extra 35-45 miles out of a tank of gas that I dump one of these into. so that makes it about = to a gallon of gas for me. and a gallon of gas costs a bit more than one of these so its worth it but your not going to get rich off of the savings. but maybe its keeping fuel injectors clean or doing something else for my car that im unaware of or maybe its not but with the gas it saves it seems to pay for itself anyway.
