This is a recent UOA taken from my 2.0t FSI (fuel diluting monster). The engine is modified with SII programming, intake with AEM dryflow filter and aftermarket turbo-back exhaust. This UOA comprised of mostly stop and go city driving, cold starts (late winter), as well as an auto-x event over the period of 3 months.
The latest UOA was done with Castrol 0w30 + LubroMoly MoS2 additive The treatment rate for the product was 50ml per liter of engine oil, but I emptied the entire 300ml bottle in my 5 quart sump. Other than moly, I am not sure if LM MoS2 contains any other additives. I'm also unsure of what the weight of the base oil is, given that the cSt@100C dropped from ~12 to 10, but I attribute a significant portion of that viscosity loss to the MoS2 additive given that virgin GC (3rd UOA) held up better despite more fuel and greater wear)
The second UOA is the latest version of Amsoil AFL 5w40; the last UOA is GC 0w30 with lube control.
Overall I am pretty happy with the results. For $6, the MoS2 additive doesn't appear to have any deleterious effects other than lowering the viscosity. I am considering switching to Redline 5w40 at a future date or possibly reducing the amount of MoS2 additive used. Currently the car is filled with the same GC + LM MoS2 additive and will be sampled after 4k miles.
