Hate to disagree. but there are more BYU's in a GALLON of Avgas than in
a GALLON of Mogas. Why?? Avgas weighs more per Gallon...

Most fuel type hydrocarbons have nearly the same BTU's per Lb.

From Wikipedia, the free encyclopedia:

Energy content

Gasoline contains about 34.6 megajoules per litre (MJ/l) or 131 MJ/US
gallon. This is an average, gasoline blends differ, therefore actual
energy content varies from season to season and from batch to batch,
as much as 4% more or less than the average, according to the US EPA.


Fuel type BTU/US gal Research octane

Regular Gasoline 125,000 Min 91
Aviation gasoline 120,200


BTU/US gal
Gasohol (10% ethanol + 90% gasoline) 120,900
( Research octane) 93/94
