Good to know that one works well for what it's worth, I used the Ravenol FZ in our 2018 CX-9 and after about a thousand miles so far I can say I am really really liking it. I had also added LG Platinum as well but I will tell you shifting is quicker and nice and smooth. Definitely a good alternative I think in addition to the aisinI just did a D&R of the ATF on my daughters 2021 CX-30 using Aisin's FZ fluid (4 quarts 6 ounces). I didn't drop the pan and change the filter but will do so next time. The OE fluid did turn yellowish but looked pretty clean for 37K miles. The Aisin fluid hasn't changed the shift feel and seems to work great.
I paid $14 a quart online which is about $10 a quart cheaper than the Mazda OE fluid.
PS: I posted in another thread that I changed the rear differential fluid using Royal Purple 75w90 at 25K miles and it seems to be working fine. I haven't been able to change the front transfer case fluid because the fill bolt is blocked by a bracket which wouldn't budge after I removed the bolt which appears to hold that bracket. I'm not sure how or if the dealer would change this fluid but I'm holding out for a Youtube solution.
