Just ordered another 10qt of 0W-40 Supercar from Autozone, they have promotions with home delivery that get it down to $10/qt. I've used x3 in the past but since the engine replacement i've just stuck with Supercar and am also sending the samples to Blackstone.

Oil analysis has good lubrication properties even at 10% oil life and Blackstone said an oil change near 0% would be acceptable, for me, 10% is about 6,500-7,000 miles given my highway mileage. Currently sitting at 13% oil life with 6,300 mi, average speed of 42mph and average 24 mpg. I use the Trip B setting for oil, along with a spreadsheet and the Blackstone data.
