Oil pressure is not rated in percent, it is rated in lbs. If you are going by the percent of oil life left that can be reset in the menu of the dash read outs, usually the oil change stations reset it when a service is performed. There is nothing wrong if the oil pressure is at 40 lbs at idle in fact that is very good oil pressure at idle.
