2012 was the change to the Mazda box supplied by Vitesse however there are a few 2011 cars with it fitted as well. Deejay.. yes you are correct 5w-40. engine oil. didn't recommend oil for gearbox or diffs as there are options which can be a personal choice and all are ok. I do have my own choice and am prepared to share if anyone wants to know. Of course there is also the limited slip diff variance. some were even fitted without order as the factory ran short of the standard box!
