My VOA (virgin oil analysis) would say otherwise. I run 300V for 10k intervals in my S2000, which is currently at 116k miles, and has hundreds of hours of run time at 6000+ RPM. Believe me, I'm completely anal about proactive/preventative maintenance.
We run 300V in the CSG shop cars, and our current oil change is at about 6000 miles. I can assure you that the car has seen plenty of track time
Re: 8100. It's a synthetic blend. 300V is a group V full synthetic. You want to prepare you car for the harshest condition you will expose it to (this applies to brake pads as well). If you plan on running one marathon a year, do you train by doing 2 mile jogs every day? In my experience, 8100 has broken down with JUST canyon driving; I used to use it before I ever started hitting the tracks, and UOA showed it be insufficient, even though it is a very highly regarded oil.
As always, YMMV. We change our fluids based on test results from Blackstone, and recommend that anyone interested in extended oil change intervals to do the same.
We carry the full line of Motul fluids. PM @

300V virgin oil analysis.
Oil analysis on my factory fill on the S2000 (Yes, I started from the begining)
Different oils I tried in my car, until I discovered 300V. Look at the viscosity break down. My car was strictly a daily driver/canyon carver at this point. Still zero track time!
Experimenting with different diff fluids.
