I had an oil tank out of the frame and decided to check on capacity levels.
I blocked the connections off and used water to fill to the 1 and 2 US quart levels.
Then dipped a wooden stick to find the level.
Note that this is only tank capacity, of course there will be some oil in the crankcases and lines.
Also see that only 1 quart will cover the feed line filter screen big 'bolt'.
I did this because I recall that there are several lengths of dip stick caps and level markings.
Edit: My dipstick shows on the 'L' mark right at 2 quarts.
