They have the 100 octane "low lead' which the old cars seem to love. A lot of guys also use it for gas-powered landscaping tools since the ethanol mixed fuel is really bad on them.

As for price, it is usually only around a buck more a gallon than whatever 93 octane fuel is going for at the local gas station that day.

Can you mix with normal 91 unleaded that contains ethanol?

Works almost exactly any other gas station, Drop your card in, hit 15 gallons and you're done. I would never drive my car to the pump, just load the jugs. Compared to race gas, it can be half the price. The L78 loves it, and it never goes bad. I have the timing all in just before 3k so you need to be careful with octane

This is a bit dated but most of these places are still around.

Some airports won't sell gas to walk ins, some will. The smaller the airport the better. 100LL avgas works well in old cars but will eventually be phased out.
