As long as you're within +/- 0.5 quart you're still okay...? Hard to see how someone can overfill it... if it takes 9 quart put in say 8 3/4 qt since there'll be oil after draining the oil pan...?

The 986 dip stick is not exactly easy to read compare to say one from Toyota. I use the electric gauge and don't check the dip stick after an oil change.

Actually oil overfill is a lot more common than you might think and it's the fastest way to kill your AOS. Some of the reasons:

1. Not getting the car level when draining.
2. Not allowing enough time for a complete drain.
3. Not measuring refill carefully.

I always refill with 8.5qts at first and drive the car a bit. Re-check and top off when the car is level and the gauge countdown has timed out.

FWIW my 987 only takes 8 quarts with an oil & filter change. Putting in 8.5 or 9 quarts is how you get an over-full condition
