If you add alot of a thinning oil additive like MMO, the lower viscosity of the engine oil can create a feeling of more power. about 2-5% of the engines torque is used to work the oil pump etc.
IMHO the main benefit of lubro-moly would be to improve cold starting.

Quote:
MoS2–Anti-Friction is a colloidal, molybdenum sulphide (MoS2) based solid lubricant suspension in mineral oil stabilised by a special preparation process and formulated for use in vehicle engines (petrol and Diesel). Miscible and fully compatible with all commercially-available engine oils (mineral oils, partially and fully synthetic oils).
- miscible with all commercially available engine oils
- stable even under high thermal and dynamic loading
- no deposits and absolutely compatible with all commonly used filter systems
- reduces running-in and running wear
- guarantees limp-home properties
- reduces oil and fuel consumption
- increases smoothness, reliability and economy
- proven performance with catalytic converters and turbochargers

: MoS2 suspension : grey-black : complies with MIL-M-7866 B, DEF 2304, CS 2819 : majority < 0.3 μm : approx. 3 : 0.89 – 0.90 : approx. 300 : 200 : -20
Added to the lubricating oils of engines, compressors, pumps and especially motor vehicle engines (petrol and Diesel). Miscible with all commercially available engine oils.
Add 5 % (50 ml per litre of oil) MoS2–Anti-Friction to engine oil; in motorbikes with wet clutch add 2 % (20 ml per litre of oil). Can be added to engine oil at any time. Dosage in motorbikes max. 2%!
