I just made an appointment to have my wife’s new Infiniti QX60 serviced. The service adviser says the car uses synthetic motor oil, which makes for a $95 oil change! However, my owner’s manual specifies 0W-20 SN, with no mention of synthetic. (I see where the SN classification applies to both conventional and synthetic oil.)
I sent an e-mail to Infinity Owner Services asking them if I can use conventional oil. Will be interesting to see what they say, if anything.
I'm familiar with the benefits of synthetic oil, but this is a 45K mile lease, and I'm sure the internal engine components would last for at least 200K miles with conventional oil. In fact, in 50+ years of car ownership, I have never experienced an oil related failure, except for maybe a couple noisy lifters in a 1960s Chevy V8.
