I have a Roadtrek 190 that is built on a Dodge Ram 3500. Since we had the oil and filter changed, the oil gauge drops to zero at idle after the engine comes up to temp. It comes back up as soon as the RPM's come back up. No knocking or ticking when it goes down to zero.
We have change the oil pressure switch and we have stil the same problem. Any idea to solve the problem? Thank you!
