In the winter, it often encounters cold hardship problems that often fail. It is most likely due to improper use of garbage engine lubricants. The reason is that the viscosity of ordinary lubricating oils deteriorates as the temperature decreases, and if the lubricating oil cannot reach the parts that need to be lubricated in time, the engine parts of the garbage truck run without lubrication oil film, and the wear is very large. Later, I used the low temperature cold protection lubricant, I think Shell is good, can work at 40 degrees and minus 36 degrees. In addition, I think that in the winter months, one or two engine oils will be replaced depending on the mileage. The oil selected for the two oil changes must be superior to the oil changed in other seasons in terms of performance, so as to be completely safe.
