2009 370Z, 16514 miles, 3056 miles on this oil. Bought the car used a couple months ago, so this is my first UOA. I have the service records and it has been all Nissan Ester, including the one just prior to me buying it. Switched to Castrol Edge Titanium during this change out, so we'll see how that looks in comparison. I was hoping for better viscosity, but everything else looks pretty good I think. It did use a bit of oil, maybe 4-5mm on the stick. Also switched from OEM filter to Purolator PureOne.
