roughneck; This could be very serious. Don't continue driving until you've gotten to the bottom of the problem. Could be as simple as a faulty oil pump or debris in the oil pan, blocking the pickup screen. (I say, simple, but expensive) Has this vehicle had regular maintenance? Oil and filter changed every 5000 miles?
Oil recommended is 5W30. I use 10W30 synthetic in mine. Have the oil pressure checked (Don't rely on the guage). Have not heard any problems with oil pumps on this engine, but anything is possible.
