Hi Doug, Yes sir I have encountered that before after first start up with others. They hold quite a bit that can't be easily drained.

May not need to mark the stick as the style I decided on traditionally reads 1 qt overfilled with 7 quarts in it...but will test and find out. Marking the stick and all is part of the plan if needed + I'm going to make provisions for a sight tube so I can get a visual of the oil level at higher rpm.
