Summer blend oil - Page 3 - NorCal SVTOA Forums
ExxonMobil have found a way of manufacturing an engine lubricant using a blend of group III+ (Visom), group IV and group V base stocks with the same performance characteristics as a 100% PAO formulation.
The idea is that the makeup of the individual components do not matter as much as the whole formulation in its finished form. What truly matters is that there is no net loss (or there is a net gain) in operational performance in the field.
Nevertheless, some American motoring enthusiasts feel disappointed that not all synthetic products from ExxonMobil have a 100% PAO formulation.

Germany is the only market where lubricants without a 100% PAO formulation cannot be labelled fully synthetic (vollsynthetisches).
As such, Mobil 1 ESP Forumla 5W-30 is labelled Synthese Technologie in Germany, and Fully Synthetic in all other European and worldwide markets.

Yes.

It's the never ending quest.
You may actually find that European motorists (who are interested in this sort of thing) are in the same boat as you.

As I would expect with other 504/507 products.

All this searching is rather out of curiosity and to gain some enlightenment, and if I can find answers and round it down to what I will end up putting in my engine that would be a bonus.
It's so fkn hard finding hard concrete facts about brands and their products and specs, as all the info on the interwebz is so contridictory. omgz nowai?!?!
I think perhaps, the following sig of BITOG member dnewton3, one of the very few members on that forum who actually know what they're talking about, is relevant here:
Conventionals vs. Synthetics isn't about which is "better"; it's about which lasts longer, while assuring safe operation, in relation to cost. Any product can be over or under utilized. The same applies to filters.
Make an informed decision; first consider your operating conditions, next determine your maintenance plan, and then pick your lube and filter. Don't do it the other way around ...
I acknowledge the principle is a little constrained than if there were no OEM oil specifications to deal with - but for the most part, it still holds.
