Low Octane

One thing I noticed when driving across the border from Nevada to Utah (besides the sudden predominance of white people when you arrive in St. George) is the change in octane offerings at the fuel pump.

I checked my car manual to reaffirm that 87 is the lowest recommendated octane for my car (a 2015 Honda Civic). Turns out 85 is a holdover for old cars (i.e. with carburetors) running at high altitude, so it’s still available in mountain states with old cars and low budgets.
