premium gas..

It says you can use 87 octane in it but don't take it over I think it was 4k rpm I could be wrong.
Cheap bastard 3-4 dollars a tank won't kill you.

Simple question, simple awnser....
If you fill your tank up with the Reg, you'll probably be able to hear detonation (aka
inging sound from engine)
This is due to the lower octane level, which in turn combusts faster (at a lower temp) than premium would....
Hope that helps...

Octane is an additive to fuel to help prevent detonation, the higher the octane the harder it is to detonate, this is needed in higher compression ratio applications, most cars have a compression ratio of around 8:1 which is fine to run regular, in fact it would be a waist of money to run regular in a car like that, the Z has a compression ratio of 10:1 and this is the range requiring higher octane fuel to prevent premature detonation. The higher the compression ratio in general the greater horsepower per liter that an engine will produce in naturally aspirated applications. The Z like many other cars has an anti knock sensor that will retard the timing to PREVENT DAMAGE to your engine, and this reduces the compression ratio and in turn reduces horsepower. Don’t be a cheap A$$, run premium, get the max out of your car. And if you ever want to sell your z, well I know I wouldn't buy it if I knew it was ran on cheap gas for an extended period of time.

Some people shouldn't be given a driver's license. Listen Forrest, run back to "MOMMA" and "LIEUTENANT DAN" and eat your "box of choc-co-lates" and leave the discussions about the 350Z for the big boys, okay snook'ems!
Premium gas (91 octane) has a higher compression yield than the regular gasoline (87 octane). Because the Z has a higher compression engine (I forget the ratio) than most cars (passenger cars), it needs this extra yield.
During the compression stroke, 91 octane can resist a premature explosion. Using 87 octane may cause the air/fuel mixture to explode early, hence engine knocking.
The manual says that if you really need to, you can use 87 for a little bit, but must refuel with 91 ASAP. Plus 91 octane is only 20 cents more expensive, if you can afford a Z, you can go that extra step bud.
If your mommie bought your car for you, you're spoiled and you can use 87 octane.

Read page 9-3 of the owners manual.
Basically states use 91 ron or above.
If 91 ron isn't available you can use 87 ron temporary in the following conditions:
1. That you fill up the tank only partially and then you fill up with 91 ron as soon as possible.
2. Avoid full thottle or abrupt acceleration. (Knock is the worry here-Damages valves and pistons.)
Not good, not good at all.
