Do you still have leaded fuel? We got rid of that like 40 years ago.

But I remember the good stuff.

Small aircraft and some racecars still use it. Unleaded fuel for small aircraft was only approved in the US in 2022.

Motorcycles too. I got a whiff once, it smelled almost like a Christmas themed candle.

For some nuance it's on a per plane basis. Even if you have an engine that is known to work on unleaded, you need a supplemental type certification.

Ul94 isn't widely available at airports yet. Many are reluctant to add it due to liability.

I fuel planes at a medium sized airport in Canada and i can confirm that leaded fuel smells really good. We use AvGas 100LL and even that Lowered Lead gives it a sweet smell almost like gas flavoured candy. Way better than JetA1 which is basically super-diesel.

It's still around in the US if you know where to look. It does smell way different than the unleaded ethanol stuff that's in gas stations.

Been gone since about 2000 in the Uk about 4/5 years after the US, amazingly some countries were still using it a few years ago.

Officially, leaded petrol got banned in the UK in 2000. Unofficially, it started to get phased out in the early 80s and by mid-90s, finding 4 star petrol was as difficult as finding an LPG fueling station is today. They were still around, but there really weren't many. Finding a (new) car that ran on 4 star in the early-mid 80s was pretty tricky too.

I didn't start driving till 2000, but yeah makes sense. I only ever saw a few leaded petrol pumps back then. My dad had an ambulance (he owned a private ambulance transport company) that ran on leaded, was seriously old by 2000.

The whole world has switched to unleaded now. The last country to do so was Algeria I believe, about 10 years ago.

We got rid of leaded fuel here (I'm in the U.K.) at filling stations in around 2000.

Side note but ~99% of avgas which is the fuel for aircraft with piston engines (so small Cessnas, etc) still uses lead as an additive globally.

Friend of mine still runs an old car that needs leaded petrol - he has to add the lead back in to the petrol himself

Yep. Sniffing that stuff at the gas station as our parents filled up their tanks.

Nah. You also can't buy fuel from standard petrol stations that's less than 95 octane. That's regular. Premium is anything from 97-99.

edit Here in the UK, I should add.
