Hi All,

Sales man at Honda I-10 told me to mix hi-octane with normal petrol so that its around 30% , what difference does it make and where can I get it in Islamabad, I checked 3,4 petrol pumps but it wasn't there.

I got my new Honda city yesterday btw.

Thanks,
Atiq

There is no need to use Hi Octane in new Honda City. There is no such thing mentioned in Warranty Booklet. However, if you do intend to, mix it with 80:20 ratio.

No need unless your car is knocking.

^^ Honda has resolved knocking issue in fresh units by ECU reprogramming.

U sure? i went with my friend a couple days back to get the delivery of black 11 auto city. and it was knocking until he filled the tank with hi octane.

Yes, I am pretty confident as I have owned 2010 and 2011 city (M/T).
In 2010 model I had to visit dealership for reprogramming of the ECU while in 2011 at the time of delivery when I asked them to reflash the ECU they told me that knocking issue has been taken care of in new units.
Plus to test their claim I have tried to test it a couple of times and surprisingly I have not observed any kind of knocking in 2011 city so far.

I just got my Honda city AT 3 weeks back and also have 2005 Vario model. The 2005 does knock so need to fill it up with Hi octane. According to Honda people the petrol now a days has high sulfur content and this is the main reason it knocks.

I almost always used around 30% Hi-Octane in my CITY-2009 (with ECU reprogrammed). It was not intended entirely to avoid knocking problem (that actually was not there at all) - but to enjoy the extra bit of power. Moreover, I got a bit better consumption with Hi-Octane in the tank (hence somewhat off-setting the extra cost).

From my experience I will recommend to use Hi-Octane.

I normally go to CALTEX Filling Station in F-6 (Super Market) or Shell in F-7.

Congrats on getting new car. May you get to enjoy the drive of this wonderful car.

@OP
In which colour you got your new Honda City?

no need for hi-octane
it will be a waste of money
try to get normal 'super' petrol from a well reputed pump

Thanks all for your helpful replies,

I got the "RED" city, excuse my knowledge but what is a "knocking" sound?

speedster_101 2011-03-16 17:23:42 +0500 #12

Congratulations.
City in red colour looks very good.
Was that colour readily available or you waited for some days?

@poster bro i also own a 2010 city n personally i dont think u need to fill up the whole tank with hioctane.
but it would be better to use a mix hi octane with regular petrol to avoid knocking

@speedster_101 : They had the red car available in stock, in-fact there were 2 so i picked one.

But cleaning it is hell of a job

@gr8qasim: My question earlier was about "what is a knocking sound"? I have no idea about that sound.
I tried to find Hi-octane but its a difficult thing to find i guess...

Another question i have about mileage in petrol, My card did approx 760KM with 4550PKR worth of petrol (no hi-octane) , what you think of that?

speedster_101 2011-03-25 08:52:59 +0500 #16

Why it is difficult to clean?
You mean dust is more prominent on this red colour, like in case of black colour?

Congrats for the purchase!

Good to know. For the older unit owners...they usually do computer checking at 5000; if they dont; ask them to do this; its free and and tell them you are having this issue...knocking issues gets resolved after that; seems they do some reprogramming...Also dont use Honda lubricant; its not good quality; use some off the shelf synthetic lubricant...this also helps if you are having any knocking issue or higher fuel consumption.
