Hello I own a 97 dodge avenger and when I drive it the oil pressure gauge will go up and down. When I drive on the interstate or main roads the oil gauge will go up just alittle past the half way mark. Then when I apply the brakes the oil presssure will go back down to normal or sometimes below normal. I just changed the oil last wk. It didn't do this before unchanged the oil. What is causing this and should I be concerned?
