It is MY opinion (based on concrete scientific evidence, long term experience, and a documented improvement in efficiency) that MoS2 DOES reduce friction in an engine.
This may capture the real question. Does it work, does it do what it claims? Almost certainly. Do you need it? That's not so clear.
One of Liqui-Moly's MoS2 claims was 'Reduces engine wear up to 50%'. That got Trav's attention. But that claim might be modest. Most engine wear occurs in the first 5- or 10- or 20-minutes of operation. Suppose you could reduce that startup wear substantially? MoS2 should do that - it's there in the bearings like a pre-lube at start up.
Do you need it? Taxi cabs in New York don't need it because they never have cold starts. If you use a quality oil and change it occasionally, your engine will probably last 150k miles - maybe longer. At that point, you want a new car - rust, obsolescence, style changes and a host of other factors begin to intrude.

"Honey, don't you think I need a new car? The old ones got a lot of miles and my best friend Mary Lou just got the cutest sports model import!"
"Dear, your car has Liqui-Moly MoS2 in the oil. Your engine will last forever."
Maybe not the best response.

Oil companies aren't interested in an engine that lasts forever. Neither are car makers. Right now, engines last at least as long as the vehicle body - maybe even longer. What is the incentive to make the engine last even longer?
Liqui-Moly's claim advertising copy could read: "Your engine will be in top shape when the motor mounts rust through and drop the engine on the street!"

I asked YOU to provide US with concrete evidence to back up your contention that MoS2 does NOT do what they say it does. You haven't, we're still waiting.
You are obviously an MoS2 and oil additive (in general) hater. Nobody is going to convince you otherwise, you have made that fact VERY clear. So then, why are you posting ANYTHING in the oil additive section, in particular, why are you denigrating a product that you have never personally used and have absolutely NO experience with?
Right answer to the wrong question. L-M's a good company - ditto for Dow Corning. The latter deliberately decided to get out of the American consumer automobile additive market (smart company!). There just aren't enough Americans who want an engine that lasts forever. In Brazil, things may be different.
Besides, 'this stuff turns my oil black'.
