THat is a sign our guage cluster is going bad. After a while it will start loosing oil pressure when you turn on or your driving your truck. Best et is to take it to the dealership.

I had the same problem. It is the gauge cluster. I just sent my dash to mrwhizard.com. They will fix it with free shipping for 189 dollars. The dealer quoted me 580!! Very easy to get the dash out.
