Which airplanes are on the market today that require leaded gas? Specifically which power plants?
- Blackthorn 5y agoTurbocharged Lycontinentals, and higher-compression (9.5:1 or better iirc) stock Lycontinentals.
- ttt333 5y agoWithin the subset of certified, normal category piston aircraft, you will find one of these two on a sizable proportion of those airplanes.

- Aloha 5y agoI mean in current production aircraft. It appears that most versions of the O-360 can run on mogas, or unleaded gas of some sort. https://www.lycoming.com/sites/default/files/SI1070AB%20Specified%20Fuels.pdf https://www.lycoming.com/sites/default/files/SI1070AB%20Spec... Indeed, there does appear to be a 100UL drop in out here too. https://www.aopa.org/news-and-media/all-news/2021/july/27/gami-receives-unleaded-avgas-stc https://www.aopa.org/news-and-media/all-news/2021/july/27/ga...
- lutorm 5y agoI think at least all models of the Cirrus, one of the best selling general aviation planes right now, require 100 octane gas. To be clear, none require leaded fuel, per se, but until this year there was no approved unleaded 100-octane fuel.
