What is the protocol for stations that offer grades other than 87, 89, and 91 octane?

If (Shell I think) has a 91 octane High Test and a 94 octane Super High Test, which one is entered?
Does Sunoco still offer an 86 octane Extra Low? (If your car or lawnmower can run on it, that's what you'd use, instead of paying for octanes you don't need, you frugal Gas Buddy you.)
I've been to stations that offer 5 grades of unleaded gas, although the minor grades are often priced the same as the major grades.
