after break in, i have run Synthetics in everything i own that has pistons since the late '70's. Frankly, i believe all modern engine oils are superb lubricants, the synthetics are even better. For some interesting reading on engine oils you might peruse:

I believe that race oils are designed to be drained after a race, so they do not have the anticorrosion and such in them as part of their additive package.
I run Redline in my SPF, it works fine, but then, i am sure other oils are fine too. 10-40 winter, 20-50 summer.
