Lead in aviation gas could be replaced with sustainable aviation fuel.

This is BS!!!!!


Jet fuel and winter diesel are very similar, operational temperatures are the issue… at 35,000feet it is -30-40 therefore jet fuel is engineered to not gel like winter diesel.
Low sulphur diesel means lubricants for internal combustion engines must be used instead of sulphur.



We have small piston aircraft, have not been burning leaded for decades. Car gas has been used in many of these piston engines forever… downside is less hp and slower cruising speed. As 99+% of lead had been removed from the environment already…

This whole discussion is pointless and meaningless!!!

Deception and Stupidity…

Blessings and cheers!

LL100 is low lead 100 octane, the lead is there to lubricant the valves on the older piston engines, nobody will dare change the recipe. Not a lot of planes need the lead anymore.

The additive package is available to lubricate valves.

High lead gasoline won’t rot. That is 99% of the reason owners find it inconvenient to switch.

Small gasoline engines that don’t get used much, foul and run poorly on regular gasoline… should be drained and fresh gasoline every 6 months if not being used monthly. The higher the ethanol or biodiesel % the faster the breakdown and stale fuel results

2 years was nothing for diesel without biodiesel added… 6 months on summer fuel with biodiesel blend. Recking injectors and fuel pumps is at risk with stale diesel.
