Fron the Mobil 1 TriSyn Thread:
From what I have been able to decipher (See Interesting Articles Section), the Supersyn not only contains new PAO's, but also new esters, combined with powerful new antioxidants that were formerly used in jet engines. Now, it is not clear what their new friction modifier is. It could be the same friction modifier that a.) Amsoil uses in their 2000, 3000 series, b.) a new ester, c. or a new organometallic additive. I first thought it might be a new FM called "Barium Napthenate," but the Barium levels in the [oil analysis] tests so far do not bear that out. The only way to find out is to have a $400 test run, but could probably not publish the results anyway. More Oil Analysis tests, in my view, is the least costly and most practical route.
Now, just because these same constituents were used in jet engines does not make then superior in automotive applications, since the flame of combustion (and resulting blow-by) is present in automotives oils, whereas in jet engines, low starting temps and the high bearing pack temperatures and oxidation are the big concerns.
I have purchased a good number of 5 quart jugs of Supersyn 10W30 and will be doing a test this fall against Amsoil's 10W30 ATM for 5-7k intervals. I am very interested in seeing the oxidation , viscosity, and wear metal differences.
After that, I will test some of the Schaeffer's products; have already been in discussion with the local rep about my "shopping list."
