I called Amsoil tech service today to find out about the 0w-20. Heidi said she thinks about 3 more months until the new 0w-20 is out.
I also slipped in the base oil question asking her if Amsoil still uses PAO's for their top of the line oils. I brought up the M1 issue. She said "we don't comment on what base oils we use as that is proprietary information". This coupled with the rumor Amsoil is testing Group III's doesn't surprise me. It wouldn't surprise me if Amsoil is going the same route as Mobil 1. Amsoil changed their FAQ website page soon after the M1 news hit the web regarding base oils used. So it's important I think to remember to just look at the final product in real service to determine the quality of the oil and with Amsoil your getting very good quality. So, it appears to me at least that maj. PAO based oils will be a smaller market than before and that Amsoil is also going to keep all of this hush hush as well.
