I've put ~4600 on a new motor, finished the break in and my oil system upgrades (bigger oil coolers, AN lines, Sohn adapter etc.) and now I'm working on ordering water upgrades. I'm going to do a silicone hose kit, new radiator and fans, reservoir... but I have wanted to do a full HOAT coolant upgrade. I know that you cannot mix HOATs with conventional, so this would take 3-4 flushes (minimum) in order to prepare correctly or you'll get sludge. But I'm curious if there is any scientific reason for why rotary engines shouldn't use HOAT coolant? I'm doing this mid-late summer this year so if anyone has any input I would greatly appreciate it.

This is the specific coolant I would like to use:

I don't know for a fact about that coolant, but the rotary coolant seals are a little specific, non-standard coolants (specifically containing 2-EHA) will degrade the seals eventually. Is there a reason you'd like to go with that coolant specifically? What advantage are you looking for over the OEM Mazda coolant? That's usually the best least-guesswork option.
