These pictures should clarify the oil level for everyone.  \./8

Based off Tom's earlier post and my video link, there is a ring below the threads that I used to establish the correct fill level.
I also went with Odie's suggestion of 500 mL's, which at the time seemed to be perfect, but later took out about 20 mL's with a plastic  3 mL syringe to get the level below the threads. I also used my iPhone flashlight to shine in the opening to check the level. I tested the next day without any problems such as white or black smoke coming out of the exhaust.
As you notice in the video, my engine is sitting on all four motor mounts on my back porch w/o being propped up. Hope I'm giving correct info.

I've now learned to search this site - before doing anything! lol..   the manual say's .6 liters..  ya.. that's not right.

I had the EsKape motor on a bench, put in .3 L - and no way it was going to hold another .3l.   I moved the bench around worried it wasn't sitting level..

decided to hold off finishing it and by random chance... let's check out tom's site..

Saved me from making a real nube mistake!.  Thanks all for your input and wisdom.

Thanks for the great vid, Looks like .5 of a liter is about right on from what I can tell as well.

Hey Guys,   There has been a lot of discussion over the years about oil ::), what type, what weight, and how much.     Opinions will very based on experiences bad and good.     Either way, Amsoil is our best bet \./8.   I think everybody will concede that 10W-30 is the best weight.    When I first had the desire to use Amsoil, I had a discussion with an Amsoil engineer.   I explained what the characteristics are of the EX-21 motor, rpms, heat, run duration.    Based on my information he recommended the Signature Series 10W-30 Synthetic motor oil.    I asked him about the racing oil, and he indicated, that this particular oil was used in high rpm motors that in most cases would be changed after every run, therefore I would be wasting my money :(.

As far as quantity, I've tried .6L  and belched out smoke, and ended up using 18 oz's which brings the level up to the threads which is the preferred level based on Tom's analyses.

I'm sure the discussion will go on \./8

If using the factory dip stick, and ensuring the engine base is parallel to a level bench, this is the easiest method to check oil level.
