Approximately 2 years ago while driving my CEL came on. The code reader indicated low oil pressure and the oil pressure gauge was around 17-20 at idle. I changed the oil and filter and the pressure returned to normal (oil change #1). On that oil change I did two filter only changes. When due according to the oil life indicator I changed oil and new filter (oil change #2). That oil and filter was changed according to oil life indicator (oil change #3) Today while driving, once the truck warmed up, (15% on oil life monitor) the oil pressure dropped to 0 suddenly and shut engine off light came on. I pulled over shut the truck off and waited, checked oil (plenty of it), and started the truck back up. Oil pressure came back to normal and then dropped back to 0. I was close to home (<1 mile) and was able to limp home with start-stopping multiple times to maintain oil pressure. I changed oil and filter (oil change #4) and oil pressure returned to normal. Can anybody comment on what is happening? I would like to avoid running into an oil pressure issue on a longer trip, if I am only addressing the symptom and not the cause. Could the cause really be the filter getting full, or the oil degrading despite the oil life indicator suggesting there is more life?
