You have a new car. Your oil pressure is fine. Get used to it and don't bug the dealer about it. People who bug the dealer about oil pressure is why for many years we had a idiot oil pressure gage that didn't tell us the truth. Now they are coming with a true oil pressure reading. Don't ruin it for us gear heads by whining about oil pressure. If you have any oil pressure at idle you are fine. Quit worrying about it. Why do you think the idle oil pressure is low? Are you some kind of engineer? Do you know more than Ford's design engineers? Peoples opinions are over rated (mine included) so let the engineers do there job. low oil pressure at idle is normal. The oil pump isn't turning as fast as it would at crusing speed DUH!
