2014-2018 Mazda 3 Skyactiv Engine and Performance
Hi folks,
I've been doing 7,000k mile OCI's on the wife's 2.0L motor and to be frank, I have been using Pennzoil's 0w20 synthetic because it's dirt cheap with their commonly offered rebates (probably ends up being a $15 jug for a 5L bottle).
Project farm on youtube also shows it as favorable...
