What does it mean when your at a stop and your Oil Preasure goes all the way down, and u press on the gas and it goes back up? is that normal?

Yes.

On my stock gauge, my oil pressure only drops less than one line when idling. When the revs are up a bit, it's at the line above the middle line. I can't wait to install my gauges tommorow and find out what the pressure is really doing.

Oh, and my stock gauge has never gone anywhere near all the way down.

its normal to fluctuate but dropping down to nothing isn't the best... its a sign the oil pumps on its way out, i've read that minimumally you need 10psi per 1000 rpms but those are forum numbers, not from a tech article or magazine. I'd look into dropping the oil pan and inspecting the pump and pickup. good luck, i wouldn't feel comforatable below 30 psi at idle and wann have50-55psi at WOT.

+1 Hell yea! Your not even supposed to drive your car if you are below 15 psi. On my stock gauge, the most I have dropped is maybe half of a line below half way... max!

mine sits at about 25psi then shoots up to around 50 or so once i get movin. i thought it wierd but it's runnin fine

It IS normal for oil pressure to spike up like that BUT its not normal to sit at 0 when idling... that would definetly be something I would look into.

if it drops to 0 his gauge is messed up

every single mustang ive driven had a bad oil gauge

believe me if he was really at 0psi.. his motor would have went KABOOOOM!

I agree that its a good possibility that its the gauge BUT even if it was bad/innacurate it still shouldnt drop that low... I guess get a new gauge and try it out. BTW, all my gauges work perfect lol

on my car the stock oil gauge consistantly sits right at the line between normal and low
