Have a Ram 2021 and twice in a month I’ve had a low oil pressure warning light com on. This was after 200+ miles after an oil change with Valvoline. After the first warning I babied it home with oil pressure between 19 and 35 pounds. (Reading from the HUD on the dash) Dealership couldn’t tell me what the normal pressure for the eco diesel should be but that it had to drop below 8 pounds to throw the warning. Told me if the light cleared after a couple cycles it should be OK. The following morning I fired it up and it showed 88 lbs cold and no warning light. After warming up It showed 19 to 42 lbs. When looking at the oil pressure dial on the dash it pegs at about half or better making me think the HUD pressure is off. This evening, after a month from the first time, it threw the warning light a second time. Any Thoughts?
