How long is 93 octane good for?
93 octane fuels are more refined and contain more stable hydrocarbons. These stable hydrocarbons can last 2-3 times longer than 87 octane fuel. Even in proper storage 87 octane gas can start to degrade in 3 months, 93 octane fuel should last closer to 9 months before degradation is noticeable.

So, if you put in a lower octane fuel, and then go drive your car hard, press the accelerator quickly, it is possible to experience heavy knock, and possible engine damage. I will say, it is unlikely to actually happen in cars produced in the last few years, but you are certainly exposing your engine to the possibility.
What’s the difference between 87 and 93 octane gas?
The common fuel ratings (87, for instance) refer to the composition of gasoline. 87-octane gasoline is comprised of an 87 percent blend of isooctane and 13 percent n-heptane, or a blend that’s equivalent. And so forth. Nearly every gas station in America will have some form of range from 87 to 93.
