We used to stop by a certain airport to fuel our Yankee back in the day. Avgas was 48 cents a gallon. Boy, do I feel old!
You did not list mogas, the primary fuel for the world’s largest piston aircraft engine manufacturer, Rotax. When gasoline drops below $2/gallon later this year, the owners of mogas-powered aircraft will laugh all the way to the bank over others still dependent on boutique fuels like Avgas. Gasoline was $1.85/gallon in the south just a few weeks ago, and will likely be even lower in a few months, thanks to President Trump unleashing our great fossil fuel industry.
In Albuquerque, 91 Octane with Zero Ethanol – zero lead peaked at $5 per gallon as of the 1st of the month (usually hovering around $4/gallon).
