Yes. There is only a few ounces that will drain.

A Porsche mechanic asks if I have replaced my I.M.S. bearing I say no . He says that can cause low oil pressure at idle. How is that possible when the bearing is not fed oil from the pump ?

Really? Once again the IMS is blamed for everything from a burnt out tail light to a flat tire. I think at some point climate change will be blamed on a bad IMS.

Put in the updated spring and piston .Put a mechanical gauge on it today 10 psi when motor is hot with 5w-40 oil. What would be the thickest oil I could run .Live in the south west.

I use 15w-50 Mobil 1 synthetic in my 2003 in the Los Angeles area. I buy from Wal-Mart ordered from their web site delivered to my door. Free 2 day shipping on orders of $50 or more. 2 5 quart bottles will get you free shipping. You need 8.5 quarts so you need to buy 2

This is what you should use in a warm climate.

Sounds a little low to me but isn't the pressure switch set at 7 psi?
If it were me, I would try a heavier oil, Mobil 1 5W50 or 15W50. 5W50 is Porsche approved in our cars. You'll most likely get a couple (2-3 psi) more at hot idle. How about the oil filter? What is your setup? Stock or aftermarket?

Walmart has Mobil 1 15W50 on special for $27 for 5 quarts.

I have no idea what the sending unit is set at . Its one for a 996 has the warning light and pressure gauge. The electric gauge is not connected yet . For an air cleaner I'm using a cold air kit, Borla exhaust.Thank you all, you guys have been a great help . I have had the car for a little over a year so I think my biggest problem is I probably used oil that is to light from the start . I had no idea what was used in the car. Started with 0w-40...then 5w-40....Now was thinking 15w-50......What would you all think about a 60 weight oil ..?

I think that if you need anything more than a quality 5W-40, something is wrong with your engine.
