Last year i attended a Solo 1 style HPDE where the most laps i'd do at a time was 3 laps during a practice session. At the time, i apprehensive about SuperSyn, so i was using Valvoline Synpower. That turned out to be a mistake. The oil temps were obviously too high, and/or the oil was thinning out far too much, as indicated by my 15psi at idle when i pulled in after a few laps.
On friday I attended a full HPDE at BeaveRun here in PA. I'm running 4000 mile old 10w30 Super Syn with a fresh regular purolator filter now, and the oil pressure stayed consistent with what i'd get on a long highway trip (above 50psi at all times). I was very pleased to pull into the pits with 25psi of oil pressure at idle; despite the 20-30 minute sessions mostly spent over 5000 rpm.
There's a lot to be learned by reading on here and seeing UOAs and what not. But seeing it personally really makes me a lot more confident.
I'll definately pay the extra for Mobil 1 over any Group III synthetic, even the cheaper Havoline stuff.
* HPDE = high performance driving event
