Any recommendations on best fuild to use for my auto transmission on my 3? Any thing else other then the Mazda genuine stuff. It's 2013. A little over due for a change. Got 99,000km on it.
The specifications should be in your owner's manual. A well-known brand that meets the specs should work well. I think the manual says that the OEM fluid is good for life but like you, I am a bit skeptical.
In my 2011 Mazda 3S I use Redline D4 it is a little pricey @ 11.99 qrt here in VA. An outfit out of California has OEM Idemitsu Type M for about 8.50 qrt shipped.
