Originally Posted By: BrocLuno I would not get excited at 15 psi idle... I'd only make sure it had higher pressure at road speeds.... Saab motors don't die easily. And when boosted, they make a lot of smiles. Drive it and enjoy the ride Thanks! I think I'll try the oil thermostat thing, but...

Having looked at some charts of temperature vs viscosity, I tend to agree with the hot performance of the 15w50. It is probably closer to what the car should be seeing at that oil temp. Unfortunately, I don't think I would want to run a 15w in the winter unless it was totally necessary. I...

I've been considering adding an oil temp gauge for this experiment, as time and budget allow. Can't remember if my obdII scan tool has a reading for coolant/oil temp. Also I don't remember ever seeing a stock oil temp sender on the car when disconnecting the harness, so maybe it doesn't have one?

Cold pressure jumps right up to 80/85 psi which I am pretty sure is where my pressure bypass would kick in. Fresh timing cover=fresh pressure bypass spring and piston. The car has been on and off the road since 2011 when I got the low oil pressure light. It's finally back together in a way that...

Thanks for the welcome! I'm hoping a lower oil temperature will make the car seem less 'fragile.' I'm kind of wary of doing any hard driving or performance modifications with the oil pressure in question. I just posted this over at SAAB Central as well. We'll see what they have to say. Good...

This is my first post to the forum (I didn't see an introduction board..) I have a 2000 SAAB 9-3 Viggen with a checkered history that I have owned from 50k to it's current 166k. Its engine has been apart many times for various reasons (new head at 60k due to an over revving incident, new timing...
