2019 CX-5 signature first oil change - conventional or synthetic?


2016 Mazda CX-5 GT AWD w/Tech Pkg
Plano, Texas, USA
I recommend the Idemitsu 5w-30. Idemitsu makes (made?) the Mazda high moly 0w-20

The best part of this oil is it meets or exceeds the latest SP / GF-6 standard.

It claims the following improvements over GF-6:
  • 30% more protection against engine wear
  • 26-46% reduction in oil consumption for longer life
  • Up to 24% improved fuel economy
  • 90% more resistant to viscosity increases
  • Three to four times more protection against cold startups
  • 91% reduction in low-speed pre-ignition (LSPI)
  • 6% cleaner engine
