Was California, Costa Mesa, and the Unocal on 17th street. I turned 18 in 1980 and was able to get my driver's licenses finally that's why I remember it.
Thinking back I can't say will 100% certainty it was leaded, but for a few years I could get it at that station. Then it was gone.
Found this (can't vouch for it's accuracy, but...)
"1996: EPA bans the use of leaded fuel for on-road vehicles (leaded gasoline was down to 0.6 percent of 1996 gasoline sales). Lead is still used in some aviation fuels"
So maybe it was leaded as I remember.
Looks like the station is still there, looks a bit more modern, that's my Jack in the Box next door, and Alpha Beta market was just down the street, where I had a check cashing card ( pre ATMs)
