i just did a oil change about a week ago. yesterday started to notice that oil pressure is going up. was always a bit above 40 when driving now way above that when driving.. has not maxed out at the 110 on the gauge.. but now past 40 and almost out of normal area...but drops back to 40 when stopped.. any help for this one

 

Pour some Sea Foam in your oiling system, Drive around with it for a day then when you get homelater change the oil,. it might just be some dirty passages and the system needs to be cleaned up a lil.
