I will certainly agree with the not quite high quality portion of the post but the certain type moly used in formulation. I have seen it fall out of the add pack on the store shelf in a couple OTC oils that are somewhat popular here.
I have waited until a analysis came back to confirm my beliefs if a car is not driven hard Moly is not needed in formulation. Some Race motors using a certain oil I have noticed corrosion on tear down confirming my beliefs that the moly's that are bonded with sulphur and or are of the Disulphide type are not for me.Or maybe they are all bonded with sulpur but to different degrees in how and types? When is the last time you have seen a Euro long drain oil with Moly in the formulation?
Anyway I just yesterday received a 4300 mile analysis back of Mobil SS 10/30 and it appears that around 0- 5ppm was uptook " he he,took a sample and continued the run for 3k more miles,now into the next interval of three weeks and analysis of the 7300 mile oil not back and just recieved the first one". This car is driven very easy as a daily commuter-hiway only and parked on weekends.Speeds are from 60-80 MPH and rpm never over 3700 while cruise speed at 75 mph is 2700rpm " twin cam 4 cylinder automatic and 6500 rpm redline" It went on a 1k mile trip over the Thankgiving Holidays with me driving. Speeds up to 105 mph but the rpm remained relativety low and was set on 80-90 for a hour on two separate runs.
Now,another analysis where it was all hiway in my mothers car,I asked here if she ever stepped on it and she said no but cruise speed was high at times so go figure? I know now who uses certain moly's but a few I have no earthly idea yet. One Mo it seems takes more heat to activate and I think it to be the Mobil variety. Heres my Mothers 3610 mile all hiway analyisis,lotsa moly was used yet the motor was already plated? Go figure.But something was weird with this oil change and analysis from the git-go,later on that topic.

When the disulphide type moly drops out it can start the sludging problem under certain use/conditions. I have read much about this and spoke to a few in the know,,geeze no-one agrees 100 percent and I'm not talking forum . Actual personell in the labs making these oils for us and the remarks made to me were not competitive in nature about different moly's. So schools not out for me at least concerning moly,in fact I am backing away from it slowly until I learn more.I think the Mo used in the SS and Trop Artic Turbo to be safe and friendly,,I need to find out more in terms of what others are using and it's difficult for old dragboat because he's not a chemist and Mo is not shown on any MSDS's
And all companies are of the hush,hush types. We need more info on who's using what IMO and it's difficult to obtain. But something is telling me the Mobil synlube runs on the hydrodynamic part better than a dino or PAO blend and that Mo will not bond to very well machined parts and or bearings that are in like new condition. Just not sure about it all yet. GF-4 will tell us more possibly when new types Moly are used and older types exposed?
