Workhorse 8.1L Low Oil Pressure
When I am going up a hill, I am getting a Low Oil Pressure warning. I would appreciate any ideas on why this is happening and thanks.

You need to verify that the sending unit is working properly. The only way to do this is to remove it and temporarily screw in a mechanical gauge. Hot idle oil pressure is the most important. You should be able to buy a mechanical gauge for less than $50.
If your original sender WAS working properly, damage likel has already been done to your engine.
i agree, hook up a mechanical guage and see what its really doing or hook up a T fitting so you can run both the mechanical and the original and compare the readings, would also be nice to check to see what the oil temp is also doing too, as the oil will thin out as it gets hotter..
