Just to add some fuel to the fire here, the oil I tested came out of the Old style of plastic bottle, don't think that the molybdenum came from the bottle though. I will run a virgin sample of the oil, hopefully tomorrow.

The first analysis I saw using Mobil 1 SuperSyn showed very little
Molybdenum, basically a trace amount that may have been ring material. The
last one showed 50 PPM. Have you reformulated the SuperSyn?
Dear Sir:
Thanks for your request. The Mobil 1 products, prior to the mandate to
meet API SL and ILSAC GF-3 (appropriate grade), were called Mobil
1Tri-Synthetic, meeting or exceeding the requirements of API SJ and ILSAC
GF-2 (appropriate grade). With reformulation to meet or exceed API SL and
GF-3 requirements, the Mobil 1 products are called Mobil 1 with SuperSyn.
The formulations are considered proprietary. During changeover from one
formulation to the next, and depending on how much of the prior product was
being used, oil analysis can give slight variations in results until
complete conversion.

This is what I have been trying to establish as many want to think that when someone states "because of the higher film strengths of synthetics" it is assumed they are reffering to the hydrodynamic film when in reality, it is the molecular bonding on the molecular level that is superior, not hydrodynamic.quote:

I always thought film strength was defined as the pressure required to squeeze an oil film from between two parallel plates in a special fixture, per an ASTM test procedure.

George has pretty well nailed this one between the eyes. It's not just oil; email Coca-Cola & ask them just what those secret ingredients are, & see what kind of answer you get. I'd like to see the oil co's be more forthcoming too, but suspect it won't happen anytime soon.quote:
