How much oil should be on my dipstick?

[san rensho]

Really easy. The manual says check the oil with the motor up to operating temp, 100 c which is probably 45 minutes of operation. Then, with the car level, wait "several" minutes (i wait about 5) and check the oil level. When I do this, with 9.5 quarts of oil,the dipstick is right at the top. The next day, when I start the car from cold, the dash gauge shows one bar overfilled.

And by the way, I am wary of the horror stories of overfilling with oil. Check the oil level with the motor running and the oil will not even register on the dipstick. No way the crakshaft is going to aerate the oil. Obviously, if you overfill by 2 quarts you may have a problem, but when I go to the track, my major concern is oil starvation from from hard corners. I'll risk a puff of smoke from an overwhelmed aos over a spun bearing any day.
