What type of gas do you guys use for your 370z?

I wonder how much fuel they gathered for the test. When you buy fuel at a pump with one nozzle that dispenses two or three octanes, everything left in the line from the prior purchase is what you will get until the pump starts sucking your choice. Basically, you'll get a hose length of low octane before getting your high octane. If the test conducted by Good Morning America only comprised 3-5 gallons, it is very concievable that the octane value in the test sample was lower than advertised. Without knowing how the test was conducted, the test could be misleading.

As to octane, it is only necessary to run a level that keeps the engine from pre-detonating (pinging). If your car does not suffer from pre-detonation at 91 octane, it is simply a waste of money to spend for a higher rating. Also, higher octane will do little/nothing for HP, torque, or engine performance.
