              Product itself is of course favored over "ethylene glycol" because of the hazards to the enviorment of the later.

              This is where West Marine stands out. Inventory is almost always good, and in house Staff always ready to help.

                Comments about Pure Oceans -100F Engine & Water System Antifreeze, 1 Gallon:

                My sailboat's diesel engine has a heat exchanger in which one side is filled with ethyl glycol antifreeze (goes around inside the engine in a closed system and does not require any winterization) plus a raw water side that pumps outside cooling water into another side -- this needs winterizing. After haul-out I close the cooling water thru hull and fill the hose with -50 degree "red pop" antifreeze up to the strainer. Then I start the engine in neutral and pour 2 gallons of the -100 degree F "green pop" into the strainer basket; it gets pumped through the heat exchanger raw side and all the way out through the wet exhaust system. Finally, I open the thru hull and the "red pop" in the short hose drains out, protecting the hose and fittings. This SIMPLE method has worked for me for 13 years.

                    I have been using this product for 5 years to protect my engines in the harsh winter months in Michigan. I like that it has a anti corrosion agent in it.

                      Use this for winterizing my i/o boat engine. Great price at westmarine with free shipping. Cannot find cheaper locally.
                      Gets near -50 sometimes where I keep my boat, so I personally like to go with -100 AF

                      excellent packaging and fast delivery.
