Apple Valley is at a bit of elevation, so I'm surprised that your Mustang pings on Arco 91 octane up there. That little bit of elevation should reduce your octane requirements.
Also, I thought premium fuel in CA was 92 octane? That's the way it is in Oregon.
Only 20 cents more doesn't sound like much, until you multiply it by how many gallons of fuel you use. In my case, that would be an extra $3 every time I fill up. Of all the ways I spend money, burning it is among my least favorite.

87-89-91 is what we have up here. And yea idk. It only happens when I put my foot down, which is the only thing I do when I drive that car. As for the extra cost at fill-ups, eh.. It's kind of a peace at mind thing, I would rather spend the little extra money even if it doesn't do anything, just to be 100% sure.
