I got a bottle of Waterwetter this morning thru the mail. I'm going to flush the cooling system and am wondering what mix of coolant/water/waterwetter you are running for optimal cooling. I've got a cross-country drive coming up so I'm mindful of engine temps. Current coolant is 25k miles old.
I assumed that waterwetter was just an additive but according to the bottle, you can run on just water + waterwetter but this provide no freeze protection.
So .. whats your mix ?
