M10-G2k
GOST 8581-78
Motor oil M-10g2k differs from oil M-8Г2 and M-10G2 only significantly more effective compositions of additives that enables to increase the replacement time of oil successfully to use oil M-10g2k in modern cars KAMAZ, ZIL, and buses "Ikarus". G2 group oils are produced from sulfur and low-sulfur oils. All the oils of this group contain much more effective additives than the oils of the B2 group.
The high degree of doping of G2 group oils allows them to be used in more severe conditions, where high thermal stability, better antioxidant, detergent-dispersing, neutralizing and anti-wear properties are required. High-speed diesel engines, lubricated with G2 group oils, operate on distillate fuels with sulfur content up to 0.5% (mass fraction), medium and low - speed marine diesel engines with a large cylinder diameter — up to 1.5% (mass fraction).
