I feel ya on the conversion madness we use lots of measurement units at work. I work for a company that was owned by Sweeds and they went by Mils. Germans bought us and they go my Microns. The machine shop I have stuff built at goes by millimeters, inches and thousandths.

Glad to see im not the only one with oil capacity confusion.
My main reason I questioned the capacity is my dip stick looks like (well it has) been welded by an armature welder at the top portion where the blade connects to the handle. I was thinking maybe its to short. Maybe it’s a factory weld.
