I haven't seen it around here. But in Michigan it was about the same price as 91 here.

Basically the easiest way to sum it all up here is that the thinner air creates less density in the combustion chamber which essentially lowers the compression of the engine and less worry about pre detonation. the higher the oct the lower the chance of compression detonating the fuel before the spark.

The lower the compression the lower the chance of pre detonation. Does any of that make sense?

A lot of the stations earlier in the post don't carry 93 or are gone. Petro off of Parker used to be the 93 place near my house, but it's long gone.
