This morning when I started my truck the oil (idiot) light came on and I notice the (stock) pressure gauge bottom out for just a few seconds. Then everything wnet back to normal. I let the truck run a few minutes and then drove off. For about then mile it continued to happen - light on, gauge drop, normal. The truck ran fine and I did not notice and change in RPMs or acceleration. My first guess is that it's a bad/clogged sending unit, but I just wanted to hear from others to see if there is anything to be greatly concerned about at this point.
