Oil change done exactly 1600 miles ago. Its always been low(the pressure) and I check the oil level religiously. I even check it on days I dont drive. Its always been between halfway and full on the dipstick. Now its about 2 mm above full. I have only had the car a month so I haven't done ANY hard cornering or braking, lol. Just not comfortable with it enough yet.

I tried the extra quart of oil and no change in my oil pressure. Try either 5w50 or 10w50. That should bring it up a notch or two. I don't think you mentioned how many miles on the motor?

...well my oil pressure at idle is about 45 almost 65 at 3 k while driving...Though i use 15 w 50 on a rebuilt motor, and i bought a high volume oil pump....though dunno if that made a difference or not....the valve covers being tightened helped too....

somewhere around 80-100k miles. Motor swap was done before I owned it at 220,000 miles. I'm now at 273k m. So figure an average of 30-50k on a JDM engine and I'm at about 100k. Head gasket repaired @ 253,000.

After she's warmed up? Pretty good pressure. You must have tighter clearences that I do. My rods and mains are at .019-.020. I also have a Toga HV pump shimed 5mm, with 2" added to pan and baffels. I'm right now running 10w40 oil. Next time I'm going to 5 or 10w50. Never heard of the valve covers tightening up raising the pressure though. Mine are tight.

Thats a lot of miles you should be able to go 50 weight easy and it will probably help your pressure:icon_bigg
