Agreed. And if you're using the stock in-dash electric gauge, it is lying 
to you; they all read low. Back-check with a tee fitting in the rear of the 
block, using one leg of the tee for a 0-100 psi mechanical gauge and the 
other leg for the stock sender. I once borrowed a dozen new senders from a shop 
that stocked them and tried them one after another on my engine. I got 9 
different pressures- none of which agreed with the mechanical gauge. So IMHO 
the stock gauge tells me the engine is running. If I want to see my real oil 
pressure, I open the decklid and look. YMMV- J Deryke
