I don't know how I missed this before, but I found a Mazda TSB talking about the differences between M5 and Mercon V. We all pretty much know to never use Mercon V, but some of us use "Universal" ATF. Don't! Mazda specifically states this is a bad practice and could possibly damage your transmission.
I'm sure some of y'all are going to say you've used x brand and it's fine, but personally, I'm going to keep doing what I've always done: Mazda OEM fluids only. Saving $3/quart once every 30,000 miles vs having to buy a new $3,000 transmission is a false economy to me.
