Did they have to track down leaded gas? Did they just use unleaded? Did they suffer engine knock?
We didn’t “switch” to unleaded gas in the 1970s. We added unleaded, required gas stations to offer it, and vehicle manufacturers were prohibited from making new cars that required it.
Leaded gas was still being offered at some stations well into the 1990s.
Fuck, Germany introduced unleaded fuel only in 1984 and still offered leaded fuel for a long time.
It was required because of the introduction of catalytic converters, which would get damaged by lead in the fuel.
When I was at Bundeswehr I was in hospital for some time and got some thorough diagnosis. They asked me if I worked with lead in the past (no), so I seem to have at least some lead levels in my body.
(Can’t think of a I AM NOT CRAZY pun right now)
Leaded gasoline is still around. It’s rarely at the pump, though. Cars that need it can add lead by pouring it in with regular gas.
Small aircraft mostly use leaded gasoline (AVGAS100LL), as aircraft regulations change at the pace of continental drift. Most of these aircraft would run fine on an unleaded equivalent, and us GA enthusiasts hope for change in this regard.
In about 1980 they stopped selling it at the last local station and my dad and someone did something to the van to make it run on unleaded. It lasted 10 more years.
I had a 1967 mustang while this was going on in the 1980s. For awhile there was one station selling the leaded gas, then you just took your chances, use the unleaded and maybe an additive if the engine knocked, mine didn’t.
Gas stations dispensed both, like current gas and diesel.
You could also buy lead additives, more for an emergency situation than a permit solution.
From 97-2000 I drove a ‘77 GMC truck that was designed for leaded gas which was not available any more. I just used unleaded. No additives or anything. Maybe the fact it was a V8 meant it could stand being a little out of tune, but I never saw any adverse affects.
You can still buy tetraethyllead for classic cars that need it.
That is horrifying
It’s pretty uncommon though. Aviation uses far, far more leaded fuel than classic cars.
Yeah, I knew that some planes still use it. I have had a full year or so now of being horrified by that too.
I wonder if we’re still going to be selling PFAS 50 years from now too.
Only small prop planes, and not all those.
Almost all commercial aviation are jets or turboprops, using jet fuel. Jet fuel has no lead.
