In recent years, the influx of Chinese cars into the Russian market has raised concerns among motorists about operating these models in severe frosts. The intricate details of driving Chinese cars were once a topic reserved for a small group of owners, but with their widespread availability, the issue has become relevant to many.
Both the oil in the “robot” and the working fluid in the variator, like motor lubricant, have viscosity characteristics that depend on temperature. These liquids tend to thicken in cold conditions and become less viscous when warmed. The focus here is on the “frost” aspect, which some Chinese automakers may not take into account properly.
Chinese cars are predominantly driven in warm climates, which results in the use of cheaper fluids that tend to thicken at temperatures as low as -30°C. In the harsh Russian climate, where temperatures can drop to -50°C, this becomes a serious problem. The result is a scenario in which, even at -20 °C, the viscosity of these lubricants becomes too high for smooth operation of the gearbox (photo: ru.freepik.com).
