I'm currently on target to do about 6 track days this year and I drive about 10k miles/year. I'm not doing any extra changes beyond dealer service intervals. That being said, I do want to do an oil analysis. Unfortunately the dealer techs f'd up and didn't grab my sample at my April service. My SA was pissed at them.
Anyway, I plan to keep my car to about 100k miles and I'm not sweating the oil. Factory recommended works for me. After maintenance warranty is up, I might do it more often, but I dunno.
