I've noticed this tendency on M1 Vtwin and Amsoil MCS from "the stoners" as well as other labs. Both of those oils start at or around 21 cSt @ 100C and often measure higher after use. Why does the "thickening" occur? Dunno...
Some other observations:
The words "Super Syn" have never "graced" a bottle of Vtwin. No mention of Super Syn on the web site pertaining to Vtwin either. Unlike some others in the M1 line I beleive it to be a true Grp IV oil like the Amsoil MCS. They behave very similar.
As noted in a prior post, starting viscosity for Vtwin used to be 21 cSt @ 100 C. Now it is listed as 17 and change on their web site. No idea why the change all of a sudden. I will be watching future UAOs to see what the used viscosity is. Just curious I guess.
