I just went down to my 2016 24.1 and confirmed what I had thought all along. While it is tight in the engine compartment there is sufficient room to pour a quart of oil into a short funnel .
The funnel in the picture is 5 1/2 " deep and 5" across with an opening large enough to pass cold oil at the bottom.
The oil shown was for demonstration purposes only but represents a one quart bottle
