What is different about it other than the RON?? If it is just a higher octane fuel, it is a complete waste of time. Nissan specify 96RON fuel, using anything higher is of no benefit in a stock engine/tune. If it costs more, it is flushing money down the drain.

Burns hotter. So it's cleaner. If your car is tuned for it you'll get more power.

Better economy.

If your worried best to ask Nissan. Say to them you have a 350Z. ;-)

have you seen the price of that fuel? Its certainly not economical.

Tuning for it is completely stupid.

Ya i took it into my mechanic, he isnt really sure what it could be. His thoughts were either a missfiring spark plug or pinging. He said he wouldn't know until he started changing parts

Go somewhere else. A misfiring cylinder doesn't sound like pinging. ...

VQ's rarely ping, the knock sensor is pretty good at picking up knock and dropping timing out. Are you sure it isn't just a bad batch of fuel in the tank?

If it is indeed pinging, I would be looking at fuel supply. Have you changed the fuel filter at all?

Does the noise sound like nails dropping on a tin roof?

The noise been happening for a while. It only happens in certain revs, at the star it would happen between 1.7 - 2.2 but now also does it between 2.8-3.2. It sounds like a metal on metal sound, i guess it kinda sounds like nails on a tin roof. I always use bp ultimate but once last year used 95 for some reason. I dont think the fuel filter has been changed...

Check your heat shields aren't coming loose. I've had a light metal rattling sound since shortly after I got my Stagea, always around 2000-2500rpm on light/medium throttle. I came to the conclusion a long time ago it was most likely a heat shield rattling due to engine harmonics. I'm just super-lazy and haven't bothered crawling under it and prodding things around.

Another possibility: I don't know if the V35s are constructed the same as the Stageas but mine has a twin-walled exhaust, with the outer layer having corroded through, meaning lots of thin, small strips of metal to tap against the inner wall. Any day now I'm hoping the inner wall will rust through and I'll be forced to fit something better.

Performance hasn't dropped off at all, it burns almost no oil between changes (5,000km) and the noise is always under the same conditions.

      I'm pretty much healed up post surgery so I spent another almost full day out in the shed re-arranging everything to make room for all of the shit that I've taken off the car.  I need to get everything off the floor and away from the car for when I start making a massive mess stripping off the remaining body deadener and then for the the painting process.  Almost got the shed to a point now where I feel I can actually start working on the car again (clean shed clean mind or something!).  Almost 11 years of accumulated car parts, building supplies, tools, junk, etc have taken a long time to get in some sort of order again!  Most stuff is now boxed up and in the back shed if it's not car related.  Most people would still be horrified walking into my shed but it's significantly better than it was before!   For those that saw my separate post the other day, yeah I ordered one.... This version- I convinced myself to stop being a clown, wake up to yourself and realise it will take you 5 weeks to make one by which stage you're over working on the car again...  Maybe I am getting on top of my "mental ailments" and making smarter choices.... $1450 delivered which will take my miserable half-dutch arse a few days to get over having spent that much!  If I don't have a use for it straight away after my car is off it I might even see if there is a "rental market" for them.  See if anyone wants to hire it for a period of time.  $25 a week or something like that.  I'll worry about that when my car is actually ready to come off it though as that might be a while away!! There's now no excuses now for not ending up with an underside you could eat off! Away for kids sport the next few weekends so hopefully can get the rotisserie assembled ready to go for the car to go straight on it the next available weekend.

      I always use my Karcher, but it's only a little one that I picked up from Supercheap  The only issue I ever had with a pressure washer was when I was a kid cleaning coaches, they had a hi-po industrial sized petrol jobbie that would strip paint if you got to close I saying this, we have a fairly high power washer at work with a diesel powered heater that sprays water at about 60°c, it works great for removing old wax and road grime on the underbody after some foam cannon action, albeit from a "stand off" distance of a few feet

      Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!

      Did the noise appear after your sand trap adventure? Could be something got dislodged and is playing rub rub. Even a rock wedged somewhere.

      Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.
