[Farmall] Slow Cub Oil Pressure

[Mike Sloane]

You can throw some STP or equivalent into the oil, but I have a feeling 
that you are in for an overhaul of at least the pump. It could be that 
the intake screen is clogged with goop (best case), but it is more 
likely that the pump is worn out, along with the crankshaft bearings.
