Its hard to find any kind of consensus on the internet so I've given up looking for that!! But I'd be interested in seeing what rises to the top in a quick flash-poll.

A. Series I II or III

B. What antifreeze, brand / mix do you use?
(Are you hot-weather or cold weather climate)

C. Brake fluid?

D. Oil?

E. Anything else?

Thanks. This was inspired by the fact that I wanted to use Evans waterless coolant and think I'm a believer in the product, but there doesn't seem to be huge support for it - so wondering what tends to work for you all.
