I’m slowly getting back up to speed in General Aviation. I’m in Florida and stopped into an FBO to check things out. I like to compare fuel prices and it was just under $5 a gallon for 100LL. Then I got a glimpse of something I hadn’t seen before. UL94. Apparently that is the high octane mogas offered by Swift. I stared at the price perplexed, $7.80 a gallon?! Way more expensive than 100LL! I’m just thankful it’s available at the airport. I wonder if the state of Florida is taxing it because it’s equivalent to 99 octane auto fuel. I researched it a bit and just recently announced that they would be changing the color from clear to purple. Swift Fuels, which produces UL94 avgas, announced in early March 2024 that all shipments of its 94 octane, unleaded aviation gasoline will be dyed purple.

$187 for a tank full of purple fuel. I’m inclined to ponder my Rotax obsession.
