Last summer I was tooling around the midwest, including Missouri. Granted I was usually far off the beaten path. I found many gas stations that didn't have any octane 91 or better in Missouri, and some where 91 or 93 octane was cheaper than 87 octane.

I was wondering if there was a reason for that. I can see a local shop might not carry high grade if they determine it's not in demand. Is that it?

Why was high octane cheaper?

I run 93 and found 87 made my bike run like junk. It was still a great trip. You have a beautiful state! (IL, IA, MN, and WI too!)

 

I would think high grade was cheaper because people in the area run low grade and they didn't want to get stuck with the higher grade maybe? I have seen the same thing though.

 

The higher grades are methonal blends, corn is cheaper.

 

CORN .. that is correct, im from missouri, and i hauled gasoline for years, to the stations,

myself i stay away from the ethanol blended stuff, in my old car's and bikes' dry's stuff out.

but wont hurt the modern stuff.
