Back in the 1970s when we switched to unleaded gas, what did the vehicles that ran on leaded gas do?
Did they have to track down leaded gas? Did they just use unleaded? Did they suffer engine knock?

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.
No knocking?
Who's not there?
25 years ago I don’t trust my memory on that. I don’t remember knocking, but it’s quite possible it already had all the lead built up that it needed to prevent knocks. Or because it was parked on the street I just didn’t care.
