There are essential differences between high pressure rubber tube assembly of construction machinery and that of vehicle.

The oil for construction machinery has special requirements in terms of pressure and stability, viscosity, anti-wear and anti emulsification, which are slightly higher than those for vehicles, while the oil for vehicles is more focused on lightning and pour point.

Basically, the oil for construction machinery is heavy load and heavy load. The oil for vehicles is not too large according to the load of vehicles

Although these features are also available in construction machinery, they are more significant in vehicle use, so there is a subtle relationship between them, which can be replaced by each other but not as good as the special ones, and the effect can be seen only after long-term use.
