It has been proven that higher Octane gas (89-91) does not provide any better fuel economy or power, although some will still say it does. Higher Octane gas is meant to be used in cars with higher compression ratios (like race cars) to prevent premature detonation and that pinging noise. Engines that run hotter may also benefit from using it for same reason. In the western part of the states where temps are higher this may be recommended. Toyota and nissan recommend using it, but not 100% necessary.
