I'm just curious as to what grade of gasoline you use on your 350Z
i've noticed a pinging in my 06 and have had it to the dealer. The service manager also detected pinging, and i was wondering if you think it might have to do with ethanol being added to the gasoline.

The reason why is because the Z has a 10.3:1 compression which is fairly high. The question of what type of gas the Z uses is a non issue. It uses premium for a reason and nothing else should be used. This is not a question that should keep popping up once a month.
Here is a decent explanation:
Higher compression ratios produce more power, up to a point. The more you compress the air/fuel mixture, however, the more likely it is to spontaneously burst into flame (before the spark plug ignites it). Higher-octane gasolines prevent this sort of early combustion. That is why high-performance cars generally need high-octane gasoline -- their engines are using higher compression ratios to get more power.

I was just wondering what the main difference is between 89 and 91. Is
there some main ingrediant thats missing in 89 octane?

Itz cool i use 91 but sometimes i get tempted to put 89 just
cuz i think it wouldnt make a difference at all. I know we drive
a pretty good sports car but its no viper...

So if the purpose for running high octane gas is because of the compression ratio, for those who lower that ratio to turbo/supercharge the car should not have to worry about it? I run premium, because the ownners manual says run premium, and my luck something would happen to the car and the Nissan service department would be out there with some alien probe checking the octane of te gas.
