I buy the yellow stuff from wal-mart. it works well, is compatable with everything, and won't harm
the engine. btw it's only $6.00 a gallon that yeilds 2 gallons when you mix it. I have not had any
problems with it of any sort. It's coolant people.. as long as you keep an eye on acid levels and
change it when it is required it will be fine. you can buy test strips at any flaps to test it.
