We offer both regular (87 octane) and premium (91/93, depending on the market) grade. Not ethanol free but it is high quality ("top tier" in most markets).

Stocking racing gas would be awesome. (Sunoco SS100 is street legal in California, too.)

Yes actually we've gotten a surprising number of requests for this

Sounds like a niche that might work for you guys. I'm guessing the people who need that kind of fuel intersects nicely with "people who don't have time to fill up" and are willing to spend some extra money for convenience.

Plus there are very few stations which carry that fuel -- maybe 6 in the bay area.

Do this and charge extra - anyone wanting this won’t complain at the higher price.

Mid-grade (89) is just a mix of the two - it shouldn't be hard to implement.

[rdl]

Usually additives are added to premium which wouldn't be in mid-grade (not a huge cost difference, though). Usually this stuff gets mixed at the rack (along with ethanol, etc.), although there are older gas stations and cheaper stations which mix high and low on-site at the pump for medium.

That's the perception (and they are happy for you to think that), but I don't believe it's actually true.

And in any case, if it is true, a mix would simply have a lower level of additives for midgrade and that seems right to me.

I'm almost 100% certain that almost all gas stations have just two storage tanks and the pump mixes them.

Ah, it's apparently 90% have two tanks. The remaining 10% have 3 and have pre-mixed, because they had leftover tank from when they did leaded gas, and by doing this they don't need to upgrade the pumps. So it's probably old/cheap/un-upgraded stations which have 3 tanks.
