Thanks guys for all the interesting discussions.

I do remember read a couple of articles mostly from AA and yes, for newish cars(I think it is safe to say any cars around this century?) even for cars designed for 91, 95 petrol will make it runs longer distance. one number is for 15 litres will runs 3% further runs by AA around 2012. And there is another link I just found from AA:
http://www.aa.co.nz/membership/aa-directions/driver/fuel-duel-2/

So 95 and 91 almost cost same running same distance for a 2010 Suzuki Swift. I might be putting 95 on my car.

Interestingly I decided a while ago that since the manually always tell me that I should put 'Japanese regular' petrol in my car, which I think means 91, but a couple of mechanics I talked to saying I should put 95 into my imported cars, I think in that case 91 regular is indeed recommended, but 95 will make cars performance slightly better (around 3% maybe), and they ended up cost about same, so if higher performance/longer distance per tank is your think 95 make sense as well for newish cars which only need 91.

shk292: I also recently bought an Edix - a 2006 which I've been happily been running on 91 unleaded. I recently used the google translate app on my phone to decipher some of the stereo. According to that, your screen shot says specified fuel: unleaded regular gas (unleaded high octane also use)

Just tried Google translate on Android myself, works well!

Thanks for that, I always put 91 on my cars, just want to know what the manual says, that all.

Just got the car today for my wife, I am most play with the gadgets today, seem the previous owner put a HDD insides and there are heaps of songs, but I think they are all Janpanes :(

The stereo in ours has a HDD called "sound container" that automatically rips any CD you put in. It was bizarrely full of Hawaiian music when we got it (freshly imported). One of my translation tasks was finding out how to delete CDs from the HDD, Unfortunately the sound system is a non-DIN size and the radio doesn't work very well with a band expander so we're evaluating options for a sound upgrade. Great car though, although not as economical as I expected

We asked for a band expander to installed by the dealer and it didn't seems work at all, I haven't used a car with band expander before, so what do you mean the radio doesn't work very well with a band expander, for us It didn't found much channels and didn't fond the channels we are looking for out of Japan range, which seem to me it is the band expander not working?

Mark:
pstar008: Try to understand my car's manual (a Honda Edix ), I understand it is something about petrol type, but don't understand exactly what is means, as there are two lines of possible petrol types but none with some numbers?

I am pretty sure that regualr 91 is safe to use as it is a reasonable new car (2005) and not a racer car, but still curious about the it, and I also tried an on-line OCR tools and the output is crap, I am guessing it is hard for OCR because it is Japanese.

Don't know what's wrong with passing Dropbox url as Image source, but it is working now, I am posting the actual url, that should work.

https://www.dropbox.com/s/7b3s4vxfmhldhw3/2014-04-12%2018.22.24S.jpg

Running that through Google translate says that "Regular unleaded gas" is to be used, but that Higher can be used.

Japans "Regular" is about 94-95 RON .. so if you put 91RON in it here you'll get a bit of pinking going on (the lower octane fuel igniting prematurely under compression), so put in 95.

Ignore the cr@p comments about higher octanes being a con, they are sold at the pump for a reason, higher compression engines need fuel that will not ignite before the spark plug initiates the ignition (if the piston is on the way up the cylinder and the fuel ignites under compression before it has got all the way to the top it causes issues), your car is probably a medium-ish compression engine in comparison to other cars.

Wikipedia has a reasonably good article about octane ratings ... here in NZ we use RON at the pumps.

http://en.wikipedia.org/wiki/Octane_rating

According to that article from Wikipedia, regular from Japan is 89+ RON, which mean 91 here should be fine but higer octane is 96+, which also means that 91 to 95 is all well in the range of recommended fuel for my car as equivalent to regular petrol in Japan. Also in the table, from Wikipedia, regular petrol in Japan is 90. But in NZ, we have 91 as regular, put 95 it will probably goes further, and put 98/100 it will probably goes even further, but I wouldn't be bother as it cost way too much for the difference. But on the other hand, 91 95 shouldn't make much difference except one cost slightly more and make it goes further. And I think it pretty goes with all the newish Japan imported car, as they always recommend the same thing (regular or high octane are both OK).

So yeah, 91 or 95, doesn't really matter, as long as you know their difference.And I think you should try to not mixed them together as it may confuse the sensor?

The channels are offset by 4(?) MHz, so you have to tune to 97.4 if you want 101.4. But, with ours, even when correctly tuned, the signal is very weak so sound is crackly and cuts out intermittently. Currently working around this by connecting a smartphone to the AUX input and either playing stored music or using radio station apps to stream live radio. The options I have identified for a proper fix are:

Purchase a double-DIN adapter and bezel and then get an audio installer to install a suitable head unit, hoping I can get this to integrate with the reversing camera. Slightly messy because the existing audio controls are on the wheel and on the dash so these will presumably be disconnected but still there. Probably cost upwards of $600 for parts plus head unit plus installation
Fit a cheap head unit elsewhere in car, with remote control, and connect this by AUX to existing stereo for radio. Would need installer to connect to power and antenna. Cheaper solution and retains the existing HDD but not sure where the extra head unit could go

According to the car dealer, ours is offset by 10 or 20 (Mhz I think is what they mean), but I can never find the channel we want. I think it is either because the channel we want signal is too weak so it couldn't pick up or it is because it is overlap with existing station (the shifted one overlap with existing one don't need shift).

If its an import from Japan, Id probably use 95+ in it, as they don't have 91 (from what I know) in Japan, and some engines dont like our lower grade stuff after being on 95 for so long. Our 04 Nissan Wingroad ran like a bucket of crap on 91, soon as we put 95 in it, was a different car.

Hah I also own one of these Edix's, I love my 17x. I found mine to be more economical than my old subaru impreza cz 1.5!

Did anyone of you figure out how to delete songs of the HDD car stereo?

It's one of the options when you press menu (in Japanese) from the list of recorded discs. I'd recommend sitting in the car with google translate on ypur phone and working it out

Band expanders are pieces of junk that can't cope with a crowded FM spectrum these days. IMHO they're not even worth bothering with because they simply don't work well at all.

Japan does have "regular" and it actually has a lower octane rating than NZ.

Learn something every day :)
Wonder if the "regular" is just not as common as 95+, hence the advice I got (and read)...... regardless, our car ran like a dream afterwards :)

Anyone miss the days of having to give your car a "shot" when filling up ? ;)

I have a 2002 Nissan with a VQ25DE Engine.
When I first got it, I use 91 on the first few fills. I noticed a fair bit of pinking, so after that I use Super (most often, actually, I use BPs 98). Seems to me to run a lot smoother, and I think I get further out of a tank.
I have not done any actual empirical testing on this, but I'm pretty sure I get about 4-5% further on a tank.

Yup, same with me. Gave it a really good run on full tank of 95+ couple of weeks after purchasing - Auckland to Whitianga and back - got almost 600km out of it, was impressed :) Engine was a QG15DE - would love to have replaced it with an SR20DET for fun ;) But dont think wife or the financial situation at the time would have approved :-p

Japanese petrol stations are just like NZ
Every bank of pumps has Premium / Regular / Diesel
Filled my car up with Regular over the weekend (here in Jpn) @ 156 yen per/L
Anecdotally I have observed here, that just like NZ, more people fill up with regular than Premium
