The number on the yellow sign indicates octane rating. Don't let anyone tell you the higher the number the more powerful the gas is. The ratings rate the fuel's ability to resist 'predetonation' or 'pinging'. That's when the fuel ignites before it is supposed to. If your vehicle runs good on the lower octane fuel then you will gain nothing by using a higher grade. This is a dirty little secret that the oil industry doesn't want you to know.

Read it and see. They use yellow for cautionary notes to the public, perhaps the octane of the various grades, perhaps a notice they are using 10% ethanol to boost octane, perhaps an additive added in winter. Sorry, but I can't see it from here to read it to you.
