For [Naturally-Aspirated Skyactiv engines](https://en.wikipedia.org/wiki/SkyActiv), it is highly recommended that you use Mazda's own(Idemitsu) high molly GF-5 0w-20. [Arguably it is one of the best oil for skyactiv engines](http://www.cleanmpg.com/community/index.php?threads/45295/#post-357910).
Reviews of spare parts for Mazda 3
I got pirellis and it made a world of difference. Thicker side wall
I went with 16" Michelin Primacy 4 68db ones and road noise has reduced quite a bit. Plus if you're in the UK, your 16" rims will never touch the kerb!
Mazda 3 Stick shift are very fun to drive. They have the same steering rack out of the Miata with added practicality.
I’m rocking coopers on my 2012 Mazda 3 , they have been hella good !
Switched to Liquid-Moly and had good results.
I suggest going with a good set of plain powerstop rotors which have a zinc coating and are really cheap and some can argue much better quality than OEM.
33k before a pothole bubbled a side. MPG dropped 1 or 2 in my 22' turbo.
OEM batteries are crap, replace it with something better, preferably an EFB one. Also, a healthy battery should withstand that time and even more, so yours was definitely at its end.
I’m going to need a new windshield soon, that will be my 4th one.
