[AT] STP

[Phil Auten]

Ralph,
Before you do anything else, try either a new sender or a new gauge. 
My old F150 was showing low oil pressure too, and with over 200K on 
the odometer, I thought it
might be time for a new oil pump. I spoke with a couple of the 
mechanics at the local dealership ( I used to work there) and they 
suggested a new sender. I bought
one in the parts dept. for about $10, and the pressure now shows 
above the center of the gauge again, just like when I first bought it 
with 30K on it.
