I noticed that my oil pressure went down significantly when I was idling at a stoplight yesterday. It went back up after I accelerated from the light. Is this normal? Or should the oil pressure remain nearly constant after the car has warmed up?

most cars the oil pressure will go down at idle because the oil pump is turning slower when you accelerate the oil pump turns faster causing more oil pressure

That's normal. The bearings in a car aren't "oil tight" but constantly dribble a bit. This is true of a new engine. The bearings are constantly fed new oil through the oil gallery, which is a network of tubes in the block and head castings, by way of the pump which picks up oil from the sump, where it all drains back to. And there's a filter in the line. As bearings wear, they dribble more and the pump at idle is running too slowly to keep up with the bearing dribble so the pressure drops. As long as it doesn't drop too low, that's fine. But the drop can be noticeable in some engines when new, and all engines as they wear. The thing you want to keep an eye on is oil consumption. An engine should use some oil as evidence that the cylinders are being lubricated. If consumption is over a quart in 400 miles, go a grade heavier. Some makers consider a quart in 400 miles to be normal.

specific it could Robin. If there is not any audible information of a shrink in oil tension and the gauge is going to 0, it is going to surely introduce a probability of an electric powered fault. maximum electric powered faults on gauges will reason it to bypass the two one direction totally or the different direction totally. once I gauge is going to 0 there is possibly an open circuit or a bad oil tension sending unit. Many Fords have this problem, besides the undeniable fact that it is not basically Fords. i might advise which you have your motor vehicle looked at via an authorized motor vehicle technician. they gets to the inspiration of the problem and immediately confirm what's inflicting the problem.

it should stay level once it warms up
