I use Rotella regular petro for my car, since 90% of my driving is warm-weather highway driving, so I don't need the extra protection of a synthetic. But if I were living in the Midwest, or just did city driving, yeah I'd switch to the synthetic.
As for my bike, I figure the synthetic is better for high RPM's, especially since it's 5W-40 instead of 15-40 like the regular Rotella
