why does oil pressure goes up and down at highway speeds
What is your question?
I have noticed on my recent trip that the oil pressure will begin to drop and then recover at highway speeds. Oil is new and fresh with a filter change. There is no noise detected during the event. My oil pressure gauge show the pressure on the middle hash tag and then drop one hash tag and then begins to recover back to where it was ……….. Is the oil pump going out ? Is there an oil unit on the out side on the block ? Any help would be appreciated.
