That seems like a lot of oil. I might put in a quart every 3,000 miles or so, and while anecdotally some of our cars seem to burn a little more oil if they sit for extended periods, your pressure seems a little low. On a very hot day, mine will stay near 5 until the car is warmed up, and then it will drop to 2.5 at idle and full temperature. The spec is pretty low, though, I think something like a minimum of 1.8 is acceptable but that's from (long term) memory.
Thanks for your reply. Mine starts out at 5 (oil pressure) and on days in the 80s it will stay around 4 or above under load. When it is near 100 degrees, it will drop down to a 3 for brief periods when I'm idling in town. If I get out on the road and start driving again, the oil pressure will go up again. I probably should have made better observations at first.
My thoughts on oil usage were kind of off the cuff. I will do a better job of tracking that to see if it is less. There is a leak in the rear main seal, but I don't see any smoke coming out of the tailpipe at all. I wanted to wait before repairing the rear main seal, but maybe it's time. Sigh.
Monte, sounds pretty normal. My Tip Does drop to 2.5 on hotter days, but I am using 15W40 in it.
The 6 speed and 951 stay at 5 pretty much all the time with Valvoline 10W50 VR1.
Im changing them to 15W40 at next oil change and will check the hot oil press then.
Useage does seem a bit high, have you checked plugs?
