37363 Gasoline/Marine Medic Fuel Treatment With Ring Cleaner for Boats, 32-Ounce

equalivalent to Yamaha ring free at a better price

I have a 2005 Avalanche, valves are weak and smokes; I used the Fuel Medic on Tues. On Weds morning, while starting my vehicle; I notice a different sound, no valves rattling. While driving to work, I look into the rear view mirror; I notice smoke, within second my truck bark down slowly! suddenly, it pick up speed. The Fuel Medic is simply amazing, best fuel addictive on the market.

This was more watery than the previous bottle I bought. The liquid is clear in this one and thin and the first one I got was yellow and thicker. Overall don’t think it’s a problem

I've used this for years. Cleans up the fuel, took water out of my tank, saves on gas mileage. Also great for storing equipment that you don't use every day. Boats, garden equipment etc. Anything that uses gas, you need this stuff.

I have been using this stuff in my Yamaha AR210, and everything else that is subject to sitting a while with fuel in it, for a couple of years now. I have yet to have any fuel related issues. I will continue using Fuel Medics until I have a problem but I don't foresee that happening.

Best ethanol problem solving additive on the market. I have been a professional auto & marine technician for 40 years & I have never been impressed by any 'magic snake oil" type additives but having seen the results of using this in my boat fuel I now put it into all my gasoline powered equipment!

This product is not as concentrated as Yamaha ring free.

Used this in the old boat. Motor purrs like a kitten and burns clean.
