Noise from Engine/Transmission between 68-78km/h

[TK1]

Got a 07 Civic Sport Auto.
Driving at speed between 68km/h to 78km/h, I get a high pitch noise, which sounds like diff is worn out...
Took down to a dealer, and their excuse was that it is an induction noise... which I think load of crap.

Anyone having same problem?

[cracker]

maybe if you had differnt intake

[warwick108]

change your fuel mate.. I did have a problem like that once.. when I used mobil I think.. but now I just use premium

[ricki_kalsi]

What type of noise?? High pitch squeeling noise? Does it happen contantly, or only when on throttle?

[teaseR]

it could be tyre noise

[bennjamin]

do you have a aftermarket intake or any other modifications to your engine ?

[ricki_kalsi]

Yeah worn out dif is highly unlikely.

[warwick108]

mate, I get this noise when i drive 60 - 80 with light throttle.. light throttle to just gain minimal speed.. try using a different type of fuel.. I think my fd works best with v-power..

[TK1]

Car's a stock one...

warwick108,
Didn't know fuel could make any differences. Will give it a go with prmium fuel next time.
Problem with v-power though, is that it is always out of stock in Sydney Shell stations...

what about the bp premium stuff?

Hi I don't mean to hijack the thread but what fuel do you guys actually use?
The dealer told me use Premium 91 and I usually put Shell Premium 91 but I'm more inclined to go to the Premium 95 but worried that the car is not tuned for that petrol. Can someone shed me some light on this? Is it ok to put a stock FD2 civic on Premium 95 and which brand of petrol is best? As mentioned i'm more inclined to go with Shell

[warwick108]

i dont fill my car in all the time.. sometimes the old man would fill it up.. i only fill up 98 octane and where possible.. 100 octane.. but my old man only fills up the cheap stuff.. 91.. at first.. i did not know or bothered to ask him what he filled my car up with.. but i do realise the engine is running abit different.. and then i realised it was the cheaper stuff.. i find the engine is alot more harder and noisier when using the cheaper stuff..

[mkefalia]

I only picked up my car on Monday (5th) so besides the tank they put in the car, i have only filled it up twice (today was the second). If my car is so new will:

a) I have caused any damage to the engine putting in 91 octane fuel thus far?
b) since the car is only factory tuned would me putting 95 octane be ok or 98 octane?

[markCivicVti]

the engine is designed to run on 91ron. Lots of ppl run that and get great fuel economy. Its up 2 u if want to put in higher octane fuel... Won't make much diff. I run 98 for no reason.

[mkefalia]

well from the responses it seems to be better for the car as in it makes it work better and provides less wear over time. Yeah I have decided to go with the 98 RON from Shell.

[markCivicVti]

If you think your engine's life will be pro-longed just because of higher octane you're dreaming. As I said... it's designed to run reliably on 91 ron. The performance gain would be minimal... but so is the extra cost. If anything it just makes is a little smoother running. But yeah... congrats on the new FD2. If marketing material is anything to go by then 98 ron might keep the fuel injection system a little cleaner too. But yeah... one guy here (Buddha[somenumbers]) gets around 6.5 ltr/100km and he has only ever used 91 ron.


Use 98 ron if you want, just don't think 91 ron is bad for the engine.

[VTECMACHINE]

98 RON from Shell.


Thats your problem right there. Use BP ultimate, or Mobil 8000.

[cracker]

yeah BP FTW

[mkefalia]

I probably used the wrong words, obviously the petrol wont "harm" but in terms of whats best for teh car it seems that 98 RON is the best choice. I guess the only thing is to give it a go and see the results for myself.

Is BP really that much better than shell? whats the difference between the two?

[cracker]

this guy named buddah something something concluded with his research that BP is better
