Operational Features
Reviews on Rosneft 10w-40 oil (semi-synthetic) are provided by experts based on the results of the studies. Experts say that domestic lubricants guarantee high-quality engine protection against wear. This is achieved by instantly penetrating the product to all parts of the motor. The optimal viscosity index contributes to the formation of a thin but strong film of oil. It provides high-quality sliding friction pairs.
Even when the motor is operating at maximum permissible temperatures, the film does not break. In this case, dry areas on the parts do not appear. In cold weather, the fluid quickly gets to all the mechanisms, preventing the motor from “dry” starting.
Also, a set of special additives contributes to a good cleaning of the engine from soot. Dirt, soot and small particles of metal are collected from the surfaces of the mechanism and are kept in suspension for a long time. Also, the tool prevents corrosion on the metal components of the system.
