Oil Pressure Too High?

Just an observation of mine, but... I was driving on the interstate at about 70 mph in 6th (tach was hovering around 2200) and looked down at oil pressure gauge and saw it registering at 65-70 psi. Got off the interstate and at lower speeds and tach (30-40mph and 2000 rpm) and it was around the 30 psi mark. I was wondering if at highway speeds in 6th gear the oil pressure would be that high...seems a little elevated to me? The only mods I have on the car are cold air intake and catch can...any thoughts? The car has 600 miles on it...could the "break-in" period still be happening where I'm still seating the cylinders with original oil? Haven't changed the oil yet...Thanks!

...as a side note (different topic) is there a recommended rpm for sixth gear? Is 45 mph too slow for 6th? I've been reading mixed reviews saying don't drive in 6th gear unless pulling at least 2000 rpm? Is this a common rule of thumb? I just thought as long as it wasn't "bogging" down I could shift into 6th for better mileage at around 45-50 mph?

That's normal under those conditions and wot. In sixth that's fine I've been in sixth going 40 and no problem

Edit: just don't be in 6th while lets say going up a bigg ass hill or under a heavy load that'll mess it up but you should be good to go

Franklin is correct.

Thanks Franklin, Tracy! Oh, and I've also heard that it's better to have oil pressure a little high than a little low (ie, LOW oil pressure is more of a concern than high).

6th to any speed you like as long as you are not loading the engine in 6th. If you need accelerate drop down one and then shift back up. Heck I have let mie cruise at 35 in 6th. I just dont get on it without shifting down.

I had that concern too when the needle on my gauge "redlined" (if there was a red line). I took it to the dealership and they said there was a bulletin issued that this is normal and nothing to be concerned about. Perhaps that why they didn't put a redline or max number. I just find it odd that they didn't extend the pressure gauge to show some level of max and not top out at it. Would certainly save a lot of hassle from us worried consumers.

See post #28, for the GM Servce Bulletin.
