Just did several hundred miles of touring in Northern CA. As an experiment I used 87 octane the whole way, read a few articles about getting better mileage with it over 91-so I tried it.
Here's what I found.
I live in Tahoe at roughly 6000 feet. My shorter rides consist of 55mph zones, normal canyon riding. Dropping to maybe 4000 feet in elevation. Bags attached but empty. I was getting 37mpg with 91 octane. Speeds general kept below 80mph. Fairly open twisties.
On my trip, I ran 87 octane with about 15lbs in each side bag and a small tank bag. Went from 6000 feet to sea level Saw speeds as high as 120 and seemed to be traveling in the 75-85mph range on the straights/freeways and mixed in a lot of sharp turns(near stop/starts). One tank I saw 41mpg and all others were 37 or slightly higher.
Not sure what it all means, but there it is....
