2016 Mazda CX-5 GT AWD w/Tech Pkg
- Plano, Texas, USA
Honda does officially state that the owner should keep the factory fill according to normal OCI (7,500 miles) at the Break-in section in owner’s manual. And Honda also said many times they use high-moly break-in oil in factory fill. As for Mazda, the owner’s manual says they use Mazda genuine oil, and the UOA indicates the factory fill from CX-5 has very high content (~650) of molybdenum which is similar to Mazda moly 0W-20 oil. That’s why I changed the factory oil at 5K miles with OEM Mazda moly 0W-20 oil.⋯
I’m also planning on a 2K initial OC as I think there is the possibility of some benefit and I’m not a believer that Mazda, or any other mfg for that matter, uses any radically different break-in oil for the initial fill, and in any event, 95% of break-in is over at 2K miles.
