This oil has been available for a little over 13 months and seems much real world field testing been done since then . I posted a small bit of info here .

Just a note about the loose use of the term Polyol . Polyols are family of esters . Out of these comes trimethylolpropane or TMP, pentaerythritol " PE, and dipentaerythritol " Di PE " " Tri PE " ect ect .
Then there are Dibasic and Tribasic or Complex Esters to name a few out of the realm of the Polyols.
None of these can be used in an engine oil formula without use of at least some Polyalphaolefin "PAO" or some " GroupIII which has had it's inherent solvency refined out of it " to help mitigate seal swell tendancies so when one reads about triple ester technology ,ect , read between the marketing lines and think use of complex esters might be used along with something else .
Last and leaving out the fake group III synthetics , the upper tier synthetic base oil groups goes like this .
Group IV - Polyalphaolefin"s" = as more than one . Those are the only ones to make it into this group classification .
Group V - Any ester to include those not suitable for the gasoline engine due to hydrolatic stabilty ---- or lack of .
Mobil has a blending fluid called Synesstic which is not a true ester but got tossed into the group V category not long ago soon after it was brought to market . It is an Alkylated Naphthalene with very good additive solvency just as ester . PAO's are inadequate in that department and some PAO formulas actually use a small quantity of Group I base oil to aid the additive pack . As far as I know the AN is not used in their bike oil .
There are many ways to build engine oils . Knowing how most have been made in the past and present really helps narrow the choices for my uses and various engine specific/usage needs .
