5-26 Is it necessary to use lubricants with different viscosity indexes in summer and winter?

During hot summers, lubricants appear thinner, while in cold winters they thicken. Customers use different viscosity lubricants (No. 46/68 in summer, No. 32 in winter), but this variation diminishes at high temperatures in air compressors. Lubrication performance isn't related to viscosity index due to modern blending technology where additives, not base oil film, provide lubrication.

Butiran Kes

Answer: In the hot summer, the appearance of the lubricant will become thinner; in the cold winter, the appearance of the lubricant will become thicker. Customers use No. 46 or even No. 68 lubricants in the summer, and No. 32 lubricants in the winter. This is because customers do not consider that the obvious difference in the appearance of the lubricant only exists in the low temperature state. When the lubricant is running in the air compressor (at high temperature), this variation becomes very small. Therefore, the performance of the lubricant in terms of lubrication has nothing to do with the viscosity index. At the same time, the lubricant adopts modern advanced blending technology: the base oil film only acts as an additive carrier, and the lubrication effect is completed by the additive. Therefore, simply changing the different viscosity indexes will not play a practical role.

However, those with sealed components, including motors, controllers, and connectors, can also be operated outdoors. Performance IC forklifts tend to be utilized in heavy-duty applications, such as brick and lumber yards, where larger capacity and performance is required to move the heavy loads.
