Pinging on 91 octane?
Had the car for a month now, long enough to try several different kinds of gas. Car pings under low rpm light acceleration -- I've read several threads over in the tech section -- many report the sound to be something coming from the rear axle and they were confusing it with engine ping/knock.
I'm pretty certain what I'm hearing is engine pinging -- tried some fuel injector cleaner, but it made no difference. Any other Norcal folks have pinging problems with our crappy gas?

how's your acceleration?? normally or some time got weaker to acclerate on highway?? I had a ping thing on my first year of the 04 coupe, it sounds like there was some water within the engine pipe or something and weak acceleration. The dealer had to replace some gas sensor/gas regulator unit which they told me cost around $500 something and they did lubricated the rear axle's bearing too. So far, I dont hear any strange noise.
Let us know on your status....

Ambient temp seems to be a factor. On real hot days, I'll ping on low rpm take-offs in first. Cooler days, no ping.
I agree with the choice of Gas Companies too. 76 and Chevron no ping on hot days, where as, Flyers or Costco fuel, ping on hot days. Don't know about Arco or Shell.
Cali fuel basically is crap anyways...only 91 octane.

Frontier Infinity said "that's normal". I don't think it's normal for a 35k car to ping on premium gas. the IS350 doesn't ping like this.

It is in the Infiniti manual, some pinging under load condition, especially in high heat is normal.
