And some people say UOAs are worthless. It looks like the intake manifold gaskets I had replaced before the first UOA (95.6K) are leaking or I have another situation on my hands. I ran this oil up to almost 11K and was in for right at 12 months. The 1.5qt make up was not because the car burns it but rather it leaks out of the oil pan (gasket). It had a Fram Ultra filter, very impressed by it. Refilled with 5w20, 3qts M1 HM and 1.25qts PP I had left over and put on a FL901s. Knowing this now, I will have to limit my OCIs to 3K and switch to conventional to monitor the oil. I liked this oil as well, it cleaned up the engine nicely compared to what it use to look like. There was some varnish but that seemed to be reduced.
