Are there any virgin analysis of this oil? I haven't been able to find any. I've got some I can send off if there are none already done.
 
I like to know as well. I have these photos I just took to contribute. Canadian bottle shown. Still made in Belgium.

I have the results and can't get it to upload. Saved it as a pdf and saved it to my notes. Using a Mac. Site rejects the type of file.

Wuhh, at 13.1 cSt, it's a thin 40, practically a 30.


Sorry, couldn't resist.

Mobil 1 FS 0W-40 is even thinner.

Is Titanium really that good a lubricator? I know nothing about it.

More often than not, friction modifiers are there to compensate for shearing or a drop in viscosity over the life of the oil in the engine. That's one reason why you'll see some absurd amounts of Moly for example (usually dimer moly) in some 0W-20 oils. That's also why something like PUP SRT 0W-40 has around 225 ppm of trimer moly. Past 80ppm trimer moly offers very little improvement for cam wear, so the extra moly is there to keep everything running just fine when that PUP starts to shear down to a w30 oil.
 
Friction mods are to raise the fuel efficiency of the oil.

Fuel-efficient oils have an HTHS under 3.5 mCP. Friction modifiers are there to ensure that there is sufficient lubrication even when the oil film is extremely thin. I'm talking about motor oils of course.
