Thanks to all for the suggestions and opinions.
what I ultimately did was pull the dip stick and removed the sealing O ring. Using a medium grit sandpaper, I reduced the outside diameter of the dipstick barrel dimension by approximately 0.001", thoroughly cleaning the dipstick, using aerosol "disc brake parts cleaner" to insure no sanding grit remains, installing the sealing O ring and coating the dipstick's plastic barrel and O ring with the silicon grease mentioned previously.....result....problem solved....just a gentle pull is all that's required to extract the dip stick .... hot or cold engine.
Bob's procedure is exactly what I plan to do on my old 5416 and my friend's 2-year-old 11kW unit today. Mine is a borderline problem but his is so bad I could not get a good reading of the oil level.
I wonder if the plastic part of the dipstick expands with contact with oil or oil vapor.
