Alert me when someone posts in this thread:

You're patient to have waded through my long post.

Racers usually go with higher viscosity. At high rpms there's not much oil in the sump. Add g forces to that. Bad things can happen. I don't know the oil's viscosity, but the car was a '92 with a first generation B234 engine.

These posts have some clues:
http://www.saabnet.com/tsn/bb/9000/index.html?bID=296965
http://www.saabnet.com/tsn/bb/9000/index.html?bID=297349
http://www.saabnet.com/tsn/bb/9000/index.html?bID=297386

Saab clearly didn't revise the B234 to produce more power; its a tad weaker than the first generation. I just received the Saab Service Manual for model years '85-'95. I haven't absorbed all the changes yet but for sure Saab went to a lot a trouble and spent a pile of money on the revisions.

The oil pan was made bigger. The oil pump's strainer went from 20 mesh to 30 mesh. Why the more restrictive mesh? The oil thermostat changed from 167°F to 225°F. Why make it 58°F hotter? And not advise owners to use oil that can take more heat? Why did they wait until the B235 to put a stronger spring on the oil check valve?

When time permits I'll post a more complete list of B234 changes from 1st to 2nd generation.

I have clues but no proof. My gut tells me that when I change the oil and put in 5 quarts I'm backing off the ramps with an engine that is almost a half quart low. That's not a fatal condition, but not knowing bugs me.
