Do ALL new car motors 'ping'????

Hi there,

Recently purchased a 2006 Civic VTi. Ever since I've had it, i;ve noticed a pinging sound from the motor, usually under load either under hard acceleration or going up a hill.

My father in laws new Toyota RAV 4 does exactly the same thing.

I changed the fuel to a higher octane, and 95% of it went away.

Honda mechanics have noticed the ping, but basically I've been told that they can't adjust the timing, as its all set these days and to drive with the higher octance fuel.

Is it really a ping or with these v-tec motors is it someting else?

Thanks

i dont think a std motor should ever ping..
sounds very odd.. u sure tis a pping?

i got news for you...

its not a new motor, honda run these motors in for 1000kms flat stick.

it's not pinging, and if it is, stop being a tight ass and use the fuel intended by the manufacturer and stop trying to save $1 each time you refuel.

Use the recommend fuel!....

The recommended fuel is 91 RON and above.
It shouldnt be pinging... mine certainly doesnt!

What sort of ping?

just run higher octane fuel, is a couple more cents a L not worth the expense of an engine rebuild?

hey pro-ecu..

I read someone mentioned what u said.. but there doesnt seem to be any proof backing that honda runs the motors in..

I know yahmaha and i think lambo or ferrari do it...

I i havent heard any confirmation that honda do it..

BTW - not doubting you.. Im just curious..

Anyway, the 2006 VTi shouldn't ping using 91 RON. Tell your dealer the problem. If they say it is normal, get them to print it on the service report that they heard it but it is no problem, so that in the future if anything does happen, you have something to hold against them for not fixing the problem..

BTW, 98 premium for me as it gives slightly better mileage and offsets the 10 cent price premium

aaronng, I noticed you've mentioned a 10c price premium on PULP a few times. Is that the going rate in Sydney? It's only 6c here in Adelaide. Either way you know the government is getting about 50% of it.

I was under the impression that cars that aren't designed to be used with the higher octance fuel can't make full use of its potential because the ECU isn't able to make the necessary adjustments (advancing timing, i would guess). Or are people using it for cleaner combustion and lower emissions, rather than more power?

Very strange that a new engine would 'ping' as in detonate. Whether they run the engine in or nor I think if you buy a car brand new from the dealer you should expect that this sort of thing wouldn't occur.

Thanks mate. I ask a genuine question and get called a tight arse on the web by you? Who are you idiot troglodyte to call me that? My god, you are none other than PROECU........

By the way, the car manual states the motor is DESIGNED to run on 91 RON fuel.......get your facts right next time. I'll read it for you if you can't.

Hi there,

Already done that. It was picked up on the 1st service and its been noted on the service report by the mechanics.

Thanks for the constructive reply.
