I have run Schaeffer 9000 for 5 Oil Change Intervals. In the last 3 analyses, the lead numbers started climbing. Nothing too bad, just a confirmed, steady climb in the concentration. This has been reported by 3 other people (that I am aware of) on posts across several forums. Who knows if it is a real problem. Because of the lead, I have switched to Valvoline Premium Blue Extreme recently and will report the UOA when I get it. I also switched to Schaeffer 7000 in my sons 7.3L and the lead jumped up in it as well (3 OCI's). Many knowledgeable folks say Schaeffer is top notch oil, it appears that my trucks (and a few others) do not seem to "like it".
Schaeffer 9000 is in the "Group III / Group IV blend" category. It is 20-25% Group IV. Group III is defined as "severely hydrocracked" base stock. At one time, Group III was not called synthetic. Now it is allowable to call it a full synthetic - although I have read that there is a minimum amount of Group IV that has to be added in to the Group III to call it a full synthetic (I haven't confirmed this yet). The improvements in the hydrocracking process have made the Group III base stock into a very fine product. Most of what I read states that the Group III oils are the most "cost effective" oils.
You can get a clue on what base stock an oil uses from the CAS numbers in the MSDS sheets (note that the VII's get higher for the Group IV and V base stock classifications).

Note:
Viscosity Index (VI) is an empirical number indicating the rate of change in viscosity of an oil within a given temperature range. Higher numbers indicate a low change, lower numbers indicate a relatively large change. The higher the number the better. This is one major property of an oil that keeps your bearings happy. These numbers can only be compared within a viscosity range. It is not an indication of how well the oil resists thermal breakdown.

Oil change 1-7 : Lead is 0 to 1. Switched to Shaeffer 9000 after 5th OC.
Oil Change 8 : Lead is 6
Oil Change 9 : Lead is 7 (both Polaris and Blackstone)
Oil change 10: Lead is 8
OCI is apprx 5000 miles
The lead in my sons 7.3L truck came back at 11 and then 16. The copper (3 to 10) and iron (11 to 24) came up also.
Again, sorry if I am hijacking, but my point is that on some of the less commonly used oils - I would HIGHLY recommend getting the UOA work done. My numbers held low for two OCI's and then started going up. I have heard a lot of good things about Royal Purple and now Valvoline. I chose Valvoline, but I will continue w/ the UOA.
I had great numbers w/ the Motorcraft oil, but I changed it every 3k miles.
In picking an oil (stick w/ CI4+ or CJ4), I would say look for the viscosity rating you want (15W40 or 5W40, etc), then pick an oil with a high viscosity index (over 150), and then do the UOA. Probably can't go wrong w/ this approach.

I'm one of the people having the same problems with Lead and Iron numbers using Schaeffer's. My analysis came back good (Blackstone) for several changes done at 5,000 to 6,500 miles using the 9000 5W-40, and then all the sudden the last 2 analysis came back with higher wear #'s.
Schaeffer's must have changed something. I was using the CI4-Plus oil the whole time, so I can't blame it on the new CJ rating.
