Lol 18.5 gallons 91 burns slower than 87. Less volatility..

that means you are getting less than 10 miles to the gallon. And u are right it does burn slighly slower but higher octane has a faster reacting flashpoint then lower octane.

that should get in the high teens low twentys. check for a pluged exhaust and new motor dosent mean good one, those have cylynder head problems. they might not misfire but have leakdown through the exhaust valves from burned seats. a misfire may not show up but poor fuel economy will.
