Oil Analysis

To add to this I will soon (2.5k km away) have a UOA on 0w30 Mobil 1 with 18k km on it. I will be refilling with 5w30 Penzoil ultra platinum and doing another UOA to compare.

I've ran over the idea of going with a 0w40 euro spec'd oil to add to high temps at the track. I don't think I'll be going that route since a 40 weight is a bit higher than the engine is spec'd for and it really isn't needed as my oil pressure seems fine at the track.

I find it hard to believe that viscosity is an issue on your oil sample. I'm thinking it may have been lower than they expected but not a lubricating issue. Today's oils are getting darn impressive with their additives and they seem to be able to protect from sheering at crazy low viscocities. One of the reasons manufacturers are spec'ing 0w20 oils. Offers better emissions but doesn't lead to destroying rod bearings.
