I used to try and hit Lions Dragstrip a couple of days each month. It was about a 20 mile drive for me. My usual routine was fill up on Chevron Custom Supreme (no Sunocos in So Cal), and fill up at another Chevron just before entering the strip. Depending how busy it was, you could get in 5-8 runs in. My fuel gauge would be less than 1/2 when I left. Stopped the same station before going back home.
Many Saturday nights, I hung with the LA Street Racers and depending where we went to run, I could go thru a couple of tanks. Custom Supreme was a whopping $39.9. It was supposed to be 100 octane but I never saw anything that verified that. When unleaded showed up, Custom Supreme was dropped. Neither of my cars would run worth a crap on anything else. When I sold them some years later, I went to a local airport and filled them up on 116+ octane leaded aviation fuel (you could do that then); it was dyed purple as I remember and was close to $1.00 gallon. Cars ran great with that stuff in them.
