Talking about the Liqui-Moly 10W-40 MoS2.. I have reached a russian expert investigation, made by their most famous magazine: "ZA RULIOM" (which means BEHIND THE WHEEL, or something like that)
It is an interesting article, surely worth reading: http://www.zr.ru/articles/37413
I will make a short summary, for those who do not understand russian:
They tested 3 brands:Liqui-Moly 10W-40 with MoS2, ELF Competition STI 10W-40, Marly Carat Black Gold 10W-40 with graphite. Tehe ELF is a normal, "conventional" semi-synthetic oil, the others have anti-friction substances (hard particles additives). Here is the conclusion
1. Liqui Moly MoS2 leichtlauf with molybdenum disulfide. Semisynthetic. Specification: SAE of 10W40; API SJ/CF; ACEA A3-98, B3-98. Price - 180 rub. for a liter. In comparison with "conventional" oil 10W-40, it showed reduction in the friction to 31,9% and of wear to 21% with worse penetrating power and the tendency toward the early agglomeration. Desirably precise observance of the periodicity of replacement.
2. Marly Black Gold Carat with graphite. Semisynthetic. Specification: SAE of 10W40; API SJ/CF; ACEA A3-98, B3-98. Price - 160 rub. for 1 liter. In comparison with "conventional" oil it showed reduction in the wear to 15,8% worse penetrating power and tendency toward the early agglomeration. Desirably precise observance of the periodicity of replacement. With the approximation toward the end of the period of service cast looks to the oil pressure indicator.
3. Elf Competition STI without additives of solid particles. Semisynthetic. Specification: SAE of 10W40; API SJ/CF; ACEA A3-98, B3-98. Price - 145 rub. for 1 liter. Next to the "unconventional" competitors worthily protected the honor of the "conventional" oils. Without special additives it showed the larger wear and the coefficient of friction, but in this case it possesses the best penetrating power, and is NOT inclined to agglomeration or formation of sediment, it does not threaten by troubles during the disturbance of the periodicity of replacement.
Logical, don't you think? But how can one know when to change the oil with the additives?
