How many octanes does the gas that you use have?. Because on the video Difficult_attemp5 I can hear it knocking(mine did the same everytime you accelerate when I filled 83octanes(pump man error)).

Re: more footage :)


at which point can you hear it?

We use 91 octane (unleaded) and premium I think is 95 octane. but some places you can get 98 octane (mobil?).

when you start accelerating there is a CLACK then the normal sound of the engine. Time: 0:06.

That is a knocking sound.

Normally I use 95octanes(theoric ones...gas of my country SUCKS big time, I think that really it's 91oct.) with a xp3 octane boost(dont know if it's me, but I cant feel any kncck with it and timing remains always at 15, with normal gas its at 13).

Maybe the knocking sound was because of the workout you gave your exy.

I think that either ESP or an LSD would have made a HUGE difference offroad. Maybe a rear LSD/LOCKER like the ELECTRAC.

I already tried going offroad without the front and rear sway bars...not worth the effort, the difference is like 1~2 inches of wheel travel.

Is that ELECTRAC some aftermarket bolt-on accessory?

I had another listen to the clip and I think you're right - I've heard that sound on numerous occasions and I always suspected it was knocking/pinging/pre-detonation or whatever else you want to call it. I'd heard the same sound in my Pulsar when I ran it on "normal" unleaded once on a very hot day (99% of the time I put premium in it). The first time I heard it in the X-Trail 6 months ago (when I got it new), I wasn't sure if it was pinging or if that was how the engine is supposed to sound as I was still getting used to the engine sound...

Now that you've confirmed it, I might give it a full tank of premium and see if it does it anytime during that tankful, and stop driving around town (60k speed limit) with it in overdrive where it sits on 1500rpm emoticon

Richi,

Give the octane booster a go, it has solved my problem with engine pinging as nissanxtrail suggested earlier. The engine runs smoother now, so I went to Repco again and they had a sale on the octane booster and bought myself 3 of them for the future.

The quality of the petrol is just shocking and I fill my car-up always with Mobil.

I wouldnt reacomend you driving without OD. It wont make that difference, because most of the pinging...at least on mine.. occurs only when you accelerate from a stop.

Yes that it's a pinging sound, The x-trail manual recommends 95octanes for the european x-trail...this is what I use, and I never get pinging. I give my exy a lot of workouts, like going full throttle the entire highway with a lot of weight in, and NEVER get pinging with 95 octanes.

Also, in the city what is your fuel consumption? because mine is like 25L/100km(a lot of idling, and stop and go) and it doesnt matters if you go fast or slow....I find that going fast gets me better mileagle emoticon

I never noticed pinging, but there is a similiar discussion going on in the jackaroo forum about coctane choices and fuel consumption for short trips that may explain it.
Just follow this link

Re: more footage :)


I bought a 20L drum of straight toluene last year to try out in my Pulsar...

It made a huge difference, and measurable on the dyno too - 5kw @ the wheels, and it was still rising as it hadn't fully mixed in with the rest of the fuel already in the tank. I don't have any toluene left, but I have a bottle of a product called "Roil" (available through Neways (like Amway)) which is a petrol additive/octane booster. I might give that a try, too.

If it definitely is pinging, it'll only get worse with the hotter weather.



Back to the footage again - one of the earlier "attempt" ones (maybe #3 or #4) I noticed the engine free-revving quite high. I've asked Clare if she might've bumped it into Neutral gear by accident (as I was out of the car doing the filming), but she can't remember. It is interesting as if she didn't bump it into Neutral, then it's free-revved on it's own (the wheels weren't spinning because you can't heard any sliding on the mud). I wondered if anyone else has come across the situation where they've tackled some serious terrain and had the engine free-rev on them?

Maybe there was a wheel on the air.

One idea that may help you...get LFR6A-11 plugs wich are 1 step colder ones.

Nissan has a bad habit of installing the crappiest NGK plugs they can find, I used LFR6AIX-11 as a replacement part, I think that it makes a difference. The spark plugs are iridium...wich is more durable than platinum.
