More problematic to some of us is that, whatever the crap they pump in So Cal might be, it eats up carburetor bowls as well as gunking up the rest of the system. I have one friend who keeps a carb on one car at a time, if he isn't going to drive it today - it is either dry and on a shelf or on the car he will be using.
Don’t ever put ARCO gas in a car/engine that is carburater fed or you will be buying a new carburator.
That gas destroys carburators and makes them un repairable
Any gas in California will make an engine run bad if it is a few months old.
Running them dry doesn’t run them dry; what happens is that there is a small sediment reservoir at the bottom of the carb float bowl that still holds a small amount of gas and dirt, moisture and it is what will deteriorate rapidly and form harmful deposits.
When the tank is refilled this sediment is stirred up and pulled into the main metering jet, an orifice about the size of a hair, which then will starve the engine for gas.
If water is present its tension is such that the action of the piston is insufficient to draw it through the hole and allow the gas above it entry.
Ironically the quick cure for this (very small amounts of water only) is to pour about an ounce of propylene alcohol into the tank to break the surface tension of the water.
Always keep the tank full of fresh available fuel.
Amen pour out the excess and run them dry.
As you get older, just pulling the string becomes the chore if the engine is fouled and hard to start.
