Don't worry about autox runs affecting the oil. The effect is
minimal. That half mile trip to the store to buy those gherkins you
adore does more damage to the oil. :-) I stick to a 3000-3500 mile
changing schedule no matter how many autox runs I do and I can do
quite a few during a practice session.
Doing a lapping session is another matter. Spending a few
_hours_ rather than seconds near redline will probably affect the
oil. I'm assuming you're using good oil to begn with. If you use 99
cent no-name stuff, you get what you pay for. Mobil 1 is cheap
insurance for me.
Hope this helps,
