Yes, but the LA area has four. Of course the other 5 or so chains just buy
whichever is cheapest that month.

There are rules about what can and cannot go in fuel. You can put
detergents in.

The extra octane is 99.99% useless, but the extra detergents may make a
difference. Or maybe not. One high-level engineer is all I have to go on,
and he tells me I should use one full tank of good gas every few months,
and buy the cheapest I can get the rest of the time.
