I don't have the time to use the boat as often as I would like. I know fuel gets stale when it sits there. I add fresh fuel once in a while, and also add the StaBil to the gas. It must be doing a good job because I never have any issues when I go to run the boat. With a charged battery I'm ready to go. I always keep a supply of this fuel treatment in the garage.

Love it for stabilizing marine fuel. However I spilled some on the fiberglass And it made a horrible stain. After searching on the Internet it seems that lots of people have problems with stained fiberglass and stained vinyl. Why can't Goldeneagle remove the dye or Change it? I'm switching to startron

Works Great

Comments about Mercury Marine Quickleen Engine & Fuel System Cleaner:

I have used this product and will continue to do so. Seems to keep fuel fresh and fight any alcohol in the fuel. My outboard seems to run better because at .times only fuel available has alcohol in it. Another great product

Comments about Mercury Marine Quickleen Engine & Fuel System Cleaner:

I just picked up my lawn mower from the shop and they said the fuel was bad and they had to take the carburetor off and clean it and remove all of the gas. After they gave me the bill, they said you should always use STA-BIL® Fuel Stabilizer in your fuel and you would save on this type of maintenance. So I will use STA-BIL® Fuel Stabilizer from now on.

A proven WINNER!

Comments about Mercury Marine Quickleen Engine & Fuel System Cleaner:

I have used stabilizer for several years! I use it in all my seasonal equipment before it is put away for storage and in my sports car before it is put away for winter! Knowing the gas and fuel line is free of idle gum from fuel is essential to good storage!!
