Hey I have idea based on e-mail Newsletter I got, anyone willing to test theri oil and post the results ?
***
I just have got an excellent short article from SynLube (and no I am not promoting their products, but I do use them so I am on their NEWSLETTER e-mailing list).
Simply this PAO and Esters conduct heat differently and have different heat capacity !
I did not know that, so instead of super expensive test by IR you can actually in your own kitchen find out HOW MUCH synthetic is in your oil (what ever brand you are addicted to).
Here is the link:

And here is my idea.
Get plain PAO 6 from company like ExxonMobil
Get plain API SA SAE 30 motor oil form place like Wal-Mart
Put an electric heater and thermometer into any convenient container (I prefer chemical glass column) and time the heat up from 100F to 300 F.
Then you can do that with your favorite oil, and the FASTER it heats up (less energy it takes to elevate the temperature) the more PETROLEUM is in the blend!
I could se NO difference between petroleum and supposedly "synthetic" Quaker State ! But a big differentce between the SA and PAO - so this apparently does work!
Interesting, but then QS is API Group III "synthetic" so this simple test really works !!!
(My idea of course, but I discussed it with the Guy at SynLube).
