There is nothing in the maintenance manuals about this for our trucks. Back in the day ('50s), kerosene was used. But that can collect dust, so I use a dry lube.

If you look at really big trucks, they don't even have shocks, because inter-leaf friction on those heavy duty springs provides the damping.
