We have spent 50 years screwing around and doing not much but kick the can down the road. Lead WILL go away. We NEED to fix this before it gets fixed for us in a way we won’t like.
Also note that 100LL is a very poor “drop in” replacement for 80 octane, many of us had endless issues with lead fouling of plugs and sticking valves. It would totally fail the level of scrutiny the new fuels are getting.
Once Again - 94 octane avgas is the fix for about 75-80% of our airplanes with no formula issues, it is literally 100LL without the lead.
