Mike The bottle is correct. The more water the better the cooling (but the less corrosion protection and lubrication for the water pump). If you run 50/50 and then have to add some water while on the road you are still in good shape because you will only be diluting it down to the (?) 70/30 range. Having the ability to dilute safely is like carrying spare Antifreeze with you at all times. Nice to know when you are out on the road.
