Hello Oil Faithful,
This one is from Australia, one of our more prominent oil blenders here has just began to offer a new 'racing oil' using a blend of PAO Group-IV and Alkylated Naphthalene (AN) Group-V base stock. If you're not familiar with AN you can read a good article here. Searching your search engine of choice also turns up a great wealth of information
While not 100% you'd have to consider that Nulon is purchasing AN from Exxon-Mobil, although there are other suppliers, given Exxon's plase in the PAO market it's likely they have a supply agreement for these premium products.
Unfortunately these products are so new that they haven't hit retail yet, and there Product Bulletin is conspicuously lacking in critical detail. I'll likely get a VOA done once these hit store shelves and share the results. Also it appears that they have decided no not even bother qualifying these new oils with even basic API/JASO/ACEA certification. (Even though they are 'racing oils.')
I guess I'm asking has anyone had experience with Alkylated Naphthalene based oils. This is most certain the first time they have been seen on Australian shelves for automotive use. Group-V is mostly considered Esters (as well as Polyalkylene Glycol PAG,) but as we all should be aware, Group-V is simply oils that are not Groups I->IV, Esters just being the most commonly used in automotive applications.
Regards
Jordan
