It was ok after oil change but 2 days later it did it again,Spike touch red on gauge to make oil light come on but while driving goes up to about 35 to 40lbs on oil guage.
This sounds like bad news. This is how an engine will act when the oil pressure is actually low. The car is doing everything it should be. Fresh oil will help the low oil pressure as will thicker oil. Most likely Crank and Rod bearings are going bad.

in order to check the oil pressure, you have to remove the oil sending unit, then screw in the adapter of the oil pressure gage, and then remove the start relay or fuel pump relay from the fuse and relay box, under the hood on the drivers side, and then crank the engine over 3-4 turns, and then record the oil pressure, and then disconnect the oil pressure gage, and then re install the oil sending unit, replace the start relay or fuel pump relay, and then start up the car, and check the oil sending unit , to make sure it is not leaking, if your oil pressure checks out within the specs, then you are fine, if it gives you a low reading, then you could have a bad oil sending unit , or a oil pump going bad on you. i would replace the sending unit first, then see what the gage shows.

Hi!!
With motor off, engine sitting for about 5 mins. check engine oil level, it is probably low, refill to level.
Don't forget to rate this post. Good Luck.

There are very few things that you could look at to solve this problem.One take a look at the drive shaft that drives the pump for damages and excessive wear.Flush your engine to be sure your oil ports are open and be sure that the pick up and supply tubes are inserted tightly into the pump and connecting points.
