The difference is pretty negligible at sea level unless it's extremely hot outside and you're pushing the car hard for long periods. Most people don't realize this but altitude in itself is an octane booster. Less oxygen molecules to combust effectively raises the octane of a fuel slightly. That's why most rocky mountain states have 91 only.I can't find 93 anywhere close to where I live. The closest place I remember is Fredericksburg TX, which is exactly 500 miles away from my house. My question is how much less power does the Coyote make with 91 over 93? Just curious. And yes, I'm aware I'm losing about 3% for every 1K of my 4K' of altitude, which is probably the reason no 93 is available here.
