RE: normal oil temps

["Buchholz, Steven" <Steven.Buchholz@kla-tencor.com>]

Do you see a difference in the summer vs. winter?  If so, it may be that
the normal airflow through the grille and across the engine is cooling
things down too much.  My '78 Fox actually had a moveable door behind
the grille to adjust how much air went to the engine.

Next question ... do you know that the gauge is reading properly?  Many
times an improper reading is due to faulty instrumentation.  

Finally, the NF engine does have an oil cooler, which has its own
thermostat.  

Oh, yes ... one more thing ... are you sure that you're looking at oil
temp?  I confess ignorance about the '90 100Q, but I don't recall ever
seeing a factory oil temp gauge on "big" Audis ... yes, the Fox and 4kQ
did have them.  

HTH!
