Viscosity dropping is no real concern, but I agree that it shows the oil was getting beat up on the track days. Excellent showing though....I can't believe how little dissolved metals this oil report shows, even on a modern engine, but especially on one that had 8 track days on it.

M1 15w50 has been and is one of the finest oils on the market. It's cold viscosity is closer to a 10 weight. It flows very well at ~40 degrees, and is one of the best oils for cars that run an operating oil temp of over 210 degrees fahrenheit.
