The bottle itself praises the lubrication aspect. The cooling is suposed to be a bi-product. I have a couple thousand kms and still no sticking of the thermistat. Could just be coinkydink but KNOCK KNOCK (wood)But yes, I do agree that water is the best for cooler temps but as a lubricant......
Thats where Dura lube cooling system stuff comes in. Like I said the thermistat does not stick right now and next year when I get the rad flushed again, I'll get the thermistat changed also. But since the rad was just flushed I am trying to see if I can get thermistat to last. So far, so good!!!!
