Can't read it very well, but I think the red arrow is the full mark, and the green arrow is the add 1 Qt mark. Anything in between is the safe operating range "in theory". I like to keep mine full all the time.
Thank you. I know it seemed like a dumb question but its difficult to see until the oil has a bit of darkness to it!
I know I've gotten frightened at times if my oil is too clean I'm like "why am I so low on oil" until I finally see the glimmer in better light. Years ago before the rebuild my oil was black even after a fresh change, it was easier to read.
