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.

10cs is for 98 octance 6c is for the 96 ocatane

I wouldn't be too worried if the manual stated 95 RON or higher, but it states 91 RON.

the extra money doesn't worry me at all. If I have to i will. but still the fact remains that its designed to run on 91 RON no problem at all.

I'll bring it up with the dealer again.

Thanks

Yup, as Danny said, 98 octane.

You won't get any significant performance gains from using 98 in a car specced for 91 octane. But you'll have a buffer of 7 RON points for the times when there is a bad batch of fuel or if the station has done something dodgy to "water-down" the fuel.

I use 98 for the mileage gain.

With regards to pinging, any car that is running too lean for the combination of fuel octane, ignition timings and compression will do that. Doesn't need to be an old engine (although old engines tend to do this because of a blocked fuel filter, blocked injectors or just general gunk somewhere in the fuel system).

Thanks for clearing that up danny and aaronng. I thought all PULP was the same octane rating in oz. Well now I know :p

fab, keep us posted on what ends up happening, if anything.

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.

your welcome, anytime

that's not gonna help at most it will make it worse as it will put more load on the engine. On new engines you should use the required oil, 10w30.

non of this is rite....

a new car from watever company should sound immaculate for ages, even after a thrashing

i ran my civic, 05model, on 91octane, the recomended fuel, for a few weeks after i got it

and ive been running 98octane ever since, the car still sounds like its brand new, im sitting in 25k kmz

as for the power gain from 98octane, i agree that theoritically there shoodnt be any power gains, but wen i put in a fresh batch of 98, and thrash the car...the difference is massive wen compared to the stale fuel thats left in the tank b4 i refilled

love the 98, but if i wer u, id harass the shit out of the dealer because i dont think this should be happening to a brand new civic...but then again it could be a common problem with the 8th genz, i dont know

as for honda running in their engines b4 they give it to u, thats not true, as i did the running in for my car, and i havent heard of honda doing the runing in for any other models
