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.

        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.
