I cannot find the gl650's fuel requirement anywhere in my books. Can someone tell me what octane it should be?

I usually split the difference and pump in 89 octane in the Honda, usually premium or 89 in the Ural. All gas in my region of Illinois has had 10% ethanol for longer than I can remember, easily many decades now. Works just fine for me. I do add a little bit of SeaFoam now and then when I think of it.
