uhh, I think you're being sarcastic, right? Here's what the manual has to say about knocking... no 'ping' or 'pinging' found.

Octane rating tips
In most parts of North America, you should use unleaded gasoline with an octane rating of at least 87 or 91 AKI (Anti-Knock Index) number. However, you may use unleaded gasoline with an octane rating as low as 85 AKI number in these high altitude areas [over 4,000 ft (1,219m)] such as: Colorado, Montana, New Mexico, Utah, Wyoming, northeastern Nevada, southern Idaho, western South Dakota, western Nebraska, and that part of Texas which is directly south of New Mexico.

Using unleaded gasoline with an octane rating lower than stated above can cause persistent, heavy spark knock. (Spark knock is a metallic rapping noise.) If severe, this can lead to engine damage. If you detect a persistent heavy spark knock even when using gasoline of the stated octane rating, or if you hear steady spark knock while holding a steady speed on level roads, have your dealer correct the condition.
Failure to correct the condition is misuse of the vehicle, for which NISSAN is not responsible.

Incorrect ignition timing will result in knocking, after-run or overheating. This in turn may cause excessive fuel consumption or damage to the engine. If any of the above symptoms are encountered, have your vehicle checked at a NISSAN dealer or other competent service
facility.

However, now and then you may notice light spark knock for a short time while accelerating or driving up hills. This is no cause for concern, because you get the greatest fuel benefit when there is light spark knock for a short time under heavy engine load.

 

talking out the side of your neck means talking about **** you really dont know about.....

how stupid can you be azzhole?i just gave you your proof....... you are f vcking ignorant dude!

funny you have no response to my real numbers.....and wont answer dude about higher numbers w 100 in a z posted off a dyno in a reputable magizine........
talk your unknowing **** to someone else you moron!

 

oh yea azzhole i almost forgot......i dont have to try and break into the 13s....im already running them *****!are you?im running them almost stock....intake and 100 octane on 18 inch bsa wheels!

DUMB F U C K!

 

learn to read...there were already two replies to the reason the Z posted higher numbers so I figured you'd see them... sorry for assuming you're smart.

where's your timeslip.

 

As many have mentioned in other posts, our (at least my) car still pings a little at times on premium fuel, and I ALWAYS use premium fuel. So..... is the ECU retarding the timing just a little during those times to manage that slight detonation? I bet it is... just a little. We all know that retarding timing lowers power output.... So it would make sense that using fuel that allowed the ECU to keep timing at it's highest designed level where detonation was just about to (but not) occur would provide the most power..... The guy's post is not about hard core PROOF, it's just his observation. We all post simple observations; as mentioned earlier... take it with a grain of salt!

 

That's just the question I was going to ask; However, I don't think that question will be adequately answered here.

Personally, I use Exxon Supreme 93 octane; that being a function of a) my 2K2 Max being required to use 91 octane and b) the fact that Exxon here in NJ only offers 87, 89 and 93 octane.

Peace.

 

there have already been 2 "adequate answers" in this thread... scroll back.

 

well A S S H O L E .....AND MORON AND C O C K S U C K E R

I HAVE SLIPS I CAN SCAN.....DIDNT REALLY THIN \K I NEEDED TO SINCE 20 OTHER ORG MEMBERS WERE THERE WITH ME


ILL TELL YOU WHAT YOU BELIEVE WHAT YOU THINK IS NEW.....AND ILL BELIEVE REAL LIVE NUMBERS ....I DEAL WITH FACTS....AND THE FACT IS YOUR A ...F U C K I N G .....I D I O T !!!!!!!!!!!!!!!!!!!!

 

my dad always told me "if you make the other guy swear, you win, because if that's the most intelligent thing he can think of then the argument is over."

I win.

 

LOL, you kiss your mom with that mouth? I'd really like to see your sales techniques when trying to sell a car. Not flaming, but relax dude.
