doesnt make a difference there is only one plant that produces antifreeze so its all the same stuff...so go to the nearest conveience store and buy it cheap Pre Mix and dont worry about the water thing
As these engines are not wet sleeved it really doesnt matter what kind of antifreeze you use. Actually, the cheaper the better almost, something thats loaded with additives (or using tap water) can cause a buildup of in the system.
Good ol fashioned green antifreeze will do perfect. Buying the premix is usually pretty pricey, not to mention that it doesnt give much cold protection. I buy straight and mix it myself as the 50/50 premix would be frozen half of the year for me!

YKDave, what ratio do you mix for cold? I go to Colorado in the winter and it's been 15F below 0. I also go through the desert in the summer and it was 118F last time. Thanks.
50/50 is more than adequate. You can also purchase the premixed antifreeze. I run well below -20f with that. If you want to mix your own then you must use distilled water unless you want to add minerals to your cooling system and require a full cleaning in a few years. Keep it simple and use any antifreeze you want and mix with distilled water for the cheapest solution, or purchase the premixed for more money.
