Jim ,very impressive read and chart :thumb:. The mileage looks like maybe a little low, about like mine, I would like to see 22.5. I have found that 65/68 mph is the sweet spot. I also will be getting a UOA in about 1K more miles, that will put my current oil at 5K and 16K on the OUTLOOK. The oil is M1 5W30 with a M1-113 filter. We shall see. I'm curious to see your UOA as well. .
