It's in my first post to the OP

And then posted this to further explain.

Had this been a spill/fill using HOAT as the refill in this OAT system I would agree to change it out.

This all came from the fact that the OP has mixed a tiny amount into his system, in which I told him to dump the overflow bottle and refill with OAT but not to worry about flushing the entire system because the amount was small. I then went on to further state that if it was more than this such as a radiator spill/re-fill I would drain and flush the system fully.
I said above that it's the compatibility of the coolant with the system that is the problem because it prematurely causes components to corrode and this leads to sludging and that it's not the coolants mixing with themselves causing the issue. That has been my whole argument.
I proved that mixing the coolant outside the system is fine. It's when it's mixed in systems not designed for it that it's a problem.
I was really clear and stated many times that I wasn't condoning mixing coolants in systems intentionally.
So clearly you have a reading comprehension problem it seems or you just want to intentionally twist what I'm saying.
