Sort of OT but I know you guys will know whats what.



I've got a 10 ton Truck and the steering box is up for its 120,000km oil
swap.


The manual specifies "API GL4" oil for the steering box. As I understand
it that does not specify the weight of the oil.


I'm putting some 85/140 EPX Castrol oil in the differential.
Can I put some of this in the steering box and it would work fine and
not create any problems?

Would likely be a good fit.

Cheers Clare, I'll give it a go.

The worst I can imagine happening is that a very very slight increase in
steering stiffness if the viscosity is too high.
