Lubrication of chain depends on the working environment, temperature, chain speed and so on.

For open drive such as combine chain, swather chain etc., grease lubrication is recommended.
Influence of working environment For closed drive such as walking tractor chain transmission case etc., oil lubrication is recommended.

Application in the temperature range of -5°C to + 60°C is recommended.
Influence of temperature
In winter, Lower viscosity oil is recommended; But in summer, higher viscosity oil is recommended.
The lubrication method is related to chain speed.
Influence of chain speed
