You guys are kidding, right?
I'm not kidding, franken. :laughing4-giggles: Cost isn't the main issue; waste is.

Moly and graphite film work differently than grease; the grease in this compound is just the carrier. Even moly spray of high concentration could probably be used. The thin film Harris applies bonds with the thoroughly cleaned metal and lasts until it wears off, which BMW calculates as ≈40K miles. That's why there's assiduous cleaning before application. The heat generated by the initial friction on the lubricant between the parts facilitates the bonding of its main constituents to the metal, excess is slung off. Applying excess seems pointless. This sometimes seems to be a tough concept to accept because grease guns, grease barrels and grease gobs are the familiar.

Regardless, lathering up is an option anyway; we all have free will.  Bon appétit! 112350

I think it's silly to spend extra time and effort trying to get the "correct" amount when you can just slather it on and not worry about it. "Wasting" a few dimes worth of lube is a non-issue to my "deep pockets" as you put it. Over 200,000 miles my "deep pockets" could be wasting a whole $2.50! :laughing4-giggles:

I guess if one has a Type A personality then having extra lube slung off onto the inside of the bellhousing might cause one to lose sleep. Me, I  don't care. I just want my clutch splines to last.

That Chris Harris video is pretty amusing to me, especially the part where he measures the toothbrush. WTF?

That isn't a Type A personality, that's an obsessive personality. A Type A personality always tries to get in the last word.  :laughing4-giggles:

Last on this, i've received the torque wrench, so i'm able to adjust the 4 allen bolts that fixes the final drive.
I've a doubt in the Haynes, about the torque these bolts needs, someone can help me with that?

Thanks!!

I don't have the metric setting, but in my garage in the U.S. I use 28ftlb on those bolts. 

Some other settings are:
Final drive drain 17ftlb
Final drive filler 13ftlb

Swing arm:
Right side 6ftlb
Left side pivot pin 5ftlb
Left side lock nut 30ftlb

Brake caliper mount bolts 23ftlb

Front axle clamp screws 14ftlb
top fork clamp bolts 15ftlb
lower fork clamp bolts 30ftlb
Fork brace 15ftlb
Bottom of fork slider bolt 13ftlb
Fork drain screw lightly snug.  Be careful because they strip out very easily.

The BMW torque values can also be found in the BMW manual:

Final drive case/swinging arm bolts. 40 Nm

Haynes manuals are published by the British who have a unique way of butchering the English language. :yar
