Gdub Posted March 16, 2015 Share Posted March 16, 2015 Hi all, I have never used 102 octane fuel in my 2004 350gt skyline. Has anyone ever done this? Im just wondering if it could do any bad to my car? The fuel i was thinking of using is powerplusfuel 102+.

V35_Paul Posted March 16, 2015 Share Posted March 16, 2015 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. ;-) Link to comment https://www.sau.com.au/forums/topic/454808-102-octane-fuel-in-a-350gt/#findComment-7497710 Share on other sites More sharing options...
sonicii Posted March 16, 2015 Share Posted March 16, 2015 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.

Nightcrawler Posted March 16, 2015 Share Posted March 16, 2015 Yep, don't bother unless your car is specifically tuned for it, and then you have to run it ALL the time.

The Max Posted March 16, 2015 Share Posted March 16, 2015 If you want serious gains, fuel alone won't do it. Think about hardware mods first and foremost.

Gdub Posted March 16, 2015 Author Share Posted March 16, 2015 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.

scotty nm35 Posted March 16, 2015 Share Posted March 16, 2015 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? Go somewhere else. A misfiring cylinder doesn't sound like pinging. ... This.

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

Hertz Donut Posted March 17, 2015 Share Posted March 17, 2015 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.

scotty nm35 Posted March 17, 2015 Share Posted March 17, 2015 Could be the timing chain or cam advance units too. Are you able to drop it down for a listen? At least I can tell you what might be the issue. I'm in Hampton Park.
