Of course the best way to find out is ask RJ. Short of that, I wouldn't use anything except water (distilled) for start up as suggested above. As long as you have an "approved fluid" in the cooling system, what is, to the nth degree, is not critical. If you "feel better" starting out with a 50/50 mix then do that. It just makes more of a mess than water if you do happen to have a leak.
