There hasn’t been lead in gasoline since 1996 (30 years). Why are we still calling it unleaded?
96 was when they officially stopped selling it completely, but the phase out started in the 70s.
They used to be called it because they would add lead to gas to stop it from pinging.
Since then they’ve converted to using octane.
And honestly, at this point, I’m not even sure modern engines need octane.
Also, high octane doesn’t mean burns better, it means that it is less likely to explode under compression.
But anyway, I digress, why are we still calling gas unleaded?
That’s like Newton cookies advertising that their cookies are wasp larva free.
Or Highland advertising their milk is pus free.
Kind of weird you need to say it.
