oil pressure fluctuates
 

at idle the gauge runs low abt 45 as opposed to the normal 60. but while under power it runs at normal pressure. i just changed my oil to abt 200 miles ago, the oil level is fine to. is this the normal and i just havent noticed it til now or is there a problem?

around 40 at idle is pretty normal

your oil pressure will rise as the motor turns faster and the pump pushes more oil through...

Seems like a more than acceptable range for a healthy engine..

While it is normal, what weight oil are you putting in by chance?
