With one car in which halting corrosion was a primary concern (Maserati A6), Evans waterless seemed to work well.

PS: Just investigated and realized that the Fuchs coolant installed by my shop is OAT. Need to look into this incompatibility issue.
please let us know what you find. i don't think fuchs is available here, but i'm sure there are others producing similar products. i'm currently using glycol based coolant and haven't seen anything alarming but i'm always curious about things like this. i know of another lancia owner using the evans coolant that reports good performance, although slightly higher running temps.
