I'm not sure if you are aware, but the news is hitting the street that Mobil 1 Extended Performance is now mostly a Group III based motor with the latest formula change. This runs contrary to Mobil's comments over the years. Unfortunately - an Amsoil dealer of some ranking said that some of the PAO oils (outside of the XL line) now contain Group III basestock. Can you please get the information on this? Is Amsoil going to group III usage on more than the XL line? Thanks, Paul

In response to your inquiry, we do not know if MOBIL is using mostly a group III base stock. What we do know however is that it takes highly sophisticated equipment and very experienced people to actually determine the contents of a lubricant. There are few places in North America with this capability. This raises suspicion as to the accuracy of the statement made about MOBIL. Regardless of what others may or may not be doing, AMSOIL formulates with PAO basestocks and has no intentions of changing our premium formulations (ASL, ATM, TSO, etc). As for the comment made by the AMSOIL dealer, they would really have no way of knowing about the formulations, as they are confidential and proprietary.
