Works great

This is a must have for storing gasoline powered equipment for the winter, or long term. It prevents line freezing and combustion issues when starting after storage. I've never experienced engine issues, or water issues in the fuel lines for both riding lawnmowers and automobiles.

Busy worker

I always put a bottle in my full gas tank in the winter to prevent lines freezing. I also have to put a little in my old push mower that has set all winter to get it started. This works very well when moisture has gotten the the mower tanks. Makes my mowers not only start but run well. Give 5 star and highly recommend it.

I have a 96 maxima that has over 405000 miles highly recommend using the heat treatment in the winter or throughout the year. Because I have to buy real gas, not the fake gas. And I try to go to what I consider higher volume stores to make sure there's no water in the gas tank from just condensation that builds up over time and due to inclement weather. So before I use started using key treatment, there were a couple of times I went to our local QT to get gas. And I buy the 100% real gasoline, and literally there was enough water in the tank to cause my car, not the start.So the heat treatment works great.I do at 3 or 4 times in the winter.Depending on the weather and I do it in the summer every so often.But it really makes a difference.You don't want water in your gas, Hank.And sometimes the gas sits there longer than necessary.So always try to go to a very busy quick trip.I don't use small stations when I go out of town.If I drive, I try to look for the closest quick trip.Because I know they try to keep their gas as pure as possible
