During last visit to a dealership I asked for an oil change at 10k miles. I already had a synthetic oil and requested same this time.
The invoice reads:
Perform 6qt conventional oil and filter change:
performed 6qt oil and filter change
MZD5W30BK BULK
What is that "conventional oil" you think? Not synthetic?
I was under impression, that by default Mazda (this was Mazda authorized dealer) uses only synthetic oil in CX9 with turbo?
Oil type listed as MZD5W30BK does not really say it was synthetic/non-synthetic.
I want your opinion please before calling dealer. Maybe somebody has an old invoice where different oil type is mentioned?
In case they mistakenly put regular oil after synthetic - is that a big deal really?
