Oil pressure at idle (engine at normal operating temperature) 69 kPa (10 psi)-103 kPa (15 psi) Oil pressure at 2,000 rpm (engine at normal operating temperature) 207 kPa (30 psi)-276 kPa (40 psi)
Is this for 5w20 oil or 5w50 oil? The 5w50 is thicker and will cause higher pressures than the 5w20. I realize higher pressure doesn't mean better lubrication. However, from my Internet research the Boss and the track package cars come with 5w50 because Ford believes these cars are going to be tracked. If your not tracking you car, with a track package, 5w20 will be fine and better for DD. also, do you have a link to the information you have?
Edit: to add
I think I will get the oil changed tomorrow and see what changes.
