My car is a mazda 3 2019 with 25K miles
Automatic or manual?
Mazda’s already have relatively weak automatic transmissions, I’d stick to what the manufacturer recommends, in your owner’s manual.

However, if you’re talking about a manual transmission, yes, you can use whatever you wish, as long as it has the same specification.
It is an automatic and according to amsoil it meets mazdas specs.
If it meets the specs, then go ahead. Also, crosscheck with your owner’s manual.
Amsoil signature series ATF is very good! I use it in my Mazda manual transmission. Especially if you have a transmission known for being weak, Amsoil signature series will probably help make it last a little longer. It’s a little expensive, but it’s very good fluid.
