I disagree, most of my cars have an API requirement on the dipstick or fill cap.
I have never seen an API Service Category on a dipstick or fill cap, only occasionally the viscosity grade.
In any case, if you'd like to have some fun, ask your friends and relatives "what API Service Category oil does your car require?" I do this all the time. About 20% of the time I get...ahhhh, 5W-30? The other 80% of the time I get a blank stare. I have never received the right answer. These are bright people, they are just not into oil, as hard as that is to comprehend

I cannot stand this stuff - I am a chemist at an ILMA oil blender and a stakeholder in the Missouri Weights and Measures motor oil testing program. The State polled technicians at Missouri quick lubes and found nearly 40% did not know what the current API service categories were.
So yeah... even if it is on the dipstick, to most consumers it may as well be written in Klingon.
