Reviving this thread. I dropped my CX-5 off at dealer for a full synthetic oil change and they filled it with 5W-30 conventional (ugh!). They're making good on it, however, they use Ford OEM oil (they're a Ford/Lincoln/Mazda dealership.
They will drain and refill tomorrow for me.
The oil they will use is this one:
https://www.motorcraft.com/us/en_us...oils/sae-5w-30-full-synthetic-motor-oils.html (GF5/SN). Any reason to object to this this oil?
I'll answer my own question (and should google before I post! Lesson learned..):
Apparently this oil is
GF-6/SP/RC/SN PLUS, so should be pretty good stuff and perfect for my CX-5.
