Another guy today told me it was PAO. He slipped up and said afterwards that they are not supposed to say what the base oil is. With a fashpoint that high and volatility that low, their is some PAO or Ester in it. Could be all PAO.
I am going to buy some of the 5W or 10W30 Havoine synthetic the next time it goes on sell at Advance Auto. I like Havoline dino, but I am intrigued by this product. It is difficult to get (AA only), but the info looks good. Any company that can make such a good dino (Chevron/Havoline) and manufacturers both Group III and PAO materials....might have an outstanding synthetic.

I hear ya...if their is, I can't find it. I've been searching through BITOG reading up on all I've missed with Havoline. I believe that ChevronTexaco can make one **** of an oil. Their Synthetics look like the greatest sleepers out their.
The catch, as far as the Havoline 5w-20 goes, is fairly poor low temperature performance--at least according to the specs.
The measured VI of the 5w-20 (my lab does VI for me)is quite a bit better than the claimed VI, so it does make you wonder.

The M1 MC oils are pretty wicked.
I don't go by Flashpoint, but I think it does suggest some things about the base oil. It's the total package that counts but the Havoline oils, especially the dinos, are so well balanced.
I bought 6 quarts of the Havoline Synthetic 5W30 yesterday. I probably should have bought the 10W30 for my Tahoe in NC summer months, but I like the slightly higher viscosity of the 5W at operating temperatures. The Tahoe is currently filled with M1 10W30 and I plan to run it for another 2-3 weeks to about 5K. I will fill with Havoline Synthetic and see how it runs. I might wait to my second fill with Havoline Synthetic before getting a UOA. The Tahoe will be almost out of warranty by that time.
I know you can't judge by smell....but the odor is closer to M1 than Castrol Syntec . My wife caught me sniffing it and I had to explain....she thinks we are all crazy for spending so much time discussing motor oil .
