Can someone please check their 90-91 Manual for recommended octane rating?

Attached is a picture of a 91 integra manual recommending 91 octane for our cars, yet every thread Ive checked on here people are recommending 87. Can some please confirm this for me? I just moved and cant find my manual at the moment…

Thanks!

Scroll to the table of hydrocarbons.
“regular” gasoline in US and Canada 91–92 82–83 87

The fist number is the RON (91-92), the second is the MON octane, and the third is the average of the two. The average is what you see at the pumps.

Thanks man, that helped a lot. i thought I had this all figured out until I saw that damned line in the manual but RON is the operative word here…

A recommended RON 91 = aprox. 87 Octane.

Thanks again.
