If you are tracking, I would swap out the Mobil One 0W-40 for 15W-50 and change oil change intervals accordingly. The more you race, the more you change.
Might want to look at synthetic fluid in your trans also.
Lastly, might want to add water wetter to coolant, which must be fresh for racing.
But you knew all that, right!
Have fun and be safe out there!
