Oil lab test results
I found a great link to test results for over 50 oils. I take no credit for any info just wanted to pass along. Ive been running rotella t6 in virtually all my vehicles and these results aren't very favorable. SEEMS PENNZOIL ultra 5-30w had the best results, but im wary to try such a thin oil in our engines.

10W30 Valvoline VR1 Conventional Racing Oil (silver bottle) = 103,505 psi
zinc = 1472 ppm

5W30 Pennzoil Ultra, API SM = 115,612 psi
I have not been able to find this oil with the latest API SN certification. The bottle says, “No leading synthetic oil provides better wear protection”. For once, a product’s hype turns out to be true.
zinc = 806 ppm
phos = 812 ppm
moly = 66 ppm

Can our cars run fine on 5-40 or is 10-30 preferable?
How important are moly levels? Is this what moly is in reference to? Moly Basics - Bob is the Oil Guy
Once again thanks for sharing.

you have to change oil often in a rotary one of the main reasons is blowback , your oil gets contaminated with fuel and becomes less and less of a lubricant .
This is why most people dont bother with synthetics . why pay twice when you still have to change the oil same intervals .
--> FerrariChat.com - FAQ: Motor Oil Articles by Dr. Ali E. Haas (AEHaas) <--- this is my reason. I read this years ago, and it gave me an understanding on oil that Was pretty enlightening
