First complimentary oil change (4700) miles.I ask no less than three times,full synthetic please,do you have/use FULL synthetic?Yes sir,full syn it is.Pick up car,go home look at invoice,6 qts. PN 0000-77-5w30-QT SAE 5w-30 SUP PR. Do a little digging on these forums and Mazda sites,no where can I find oil is identified as synthetic.Call my dealer,kindly state i Believe this oil is rebranded castrol gtx conventional oil.He says he will check with parts..comes back and tells me I am right it is a semi-syn,which I still doubt...So the non turbo gets full synthetic,turbo gets at best semi syn.Makes no sense...They are draining and refilling with my supplied Castrol full Syn. Comments welcome.
