Jonathan, I guess it depends on what it is that you're driving. A few years back, 40 lbs was real good, even at highway speed. Some imports were a lot higher. 60 lbs sounds real good too. But with some of the tight tolerances of today's engines, that's low. And a 20 lb swing is a pretty good swing, and I'm not saying that's bad. Oil pumps are mechanical and like anything else, the higer the RPM, the more oil that's going to be moved, and the more pressure is created. Want to sleep better? Locate the specs on your truck. Stop in a parts store and leaf through a manual on your truck (Chilton's, Llyod's, etc). If you do your own work, it'd be a good idea to have one anyway. And, if your local parts store sells oil pumps, it's entirely possible that the parts book may have the specs in it (they used to). Every engine has a minimum and maximum oil pressure when it rolls off the assembly line (stock), and the real question is whether or not 40 - 60 lbs pressure is correct for your engine. It just might be. Besides, all parts stores have that one thing that you realized you needed until you stopped in and saw it setting there calling your name, so just stop in as you're driving by, and don't let that one thing happen to be an oil pump you don't need, if you don't need it. Just my thought. Mark Krzyzanowski.
