Gilles, no oil was added. oil checked fine all the previous times. The only 
difference was rotating the prop more after hearing the 1st gurgle.

The 912 series engines hold 3 liters of oil. When changing the oil and 
filter (don't forget to drain the oil that remains in the crankcase via 
the magnetic drain plug) we add exactly 3 quarts. This puts the level 
about the middle of the range. The best time to check the precise level 
of the oil is right after flying the airplane. We do this as part of 
our standard on post-flight inspection. That way we don't have to rely 
on the "hear it gurgle" method. After it cools down the level drops and 
this results in some folks adding more oil when it is not needed. FYI, 
We had about 100 hours on our last oil/filter change and added no more 
than 1 pint of oil during that entire 100 hours of flight.
