I think it would take approximately 3.14195265358979323846426433832785 tanks of fuel.

I'm guessing you eat way to many "pies" as well. :crybaby:

Hi guys,

I am wanting to get a little bit more go out of my car and while I am saving up to do my mods I thought that the easiest option to get a little bit more go out of her would be to put some 98 ron fuel in her instead of the standard 91 ron that I was putting in her. My question though is how many tanks will it take before I notice any power difference as I have heard you won't notice any difference on the first tank?

Thanks

Mate I had a N/A XR6 before I got the turbo and I couldn't pick any difference in performance between 91, 95 and 98 RON. For some reason I seemed to get the best economy out of 95 so that's what I ran most of the time plus I figured for the extra few cents it couldn't do any harm.

says the man who got the 2.2 60ft in his zf 6speed, looks like the car was struggling to get that extra ballest in the car moving :laughing::spoton:

Excuse me Mr No time manual boy :laughing: First ever ran as well :kissmy:

In a naturally aspirated car, the tune of the Ford ECU is such that it will be optimised to run on 95 octane and cope with 91 octane.

In trials, the reason for double blind trials (where the recipient is not aware of whether they are receiving the actual product vs a placebo) is that there is a observable part of the sample that may notice an improvement with a placebo. This is because they believe that they are receiving something different and change their behaviour.

Lots of folk I know have told me that their fuel economy has improved from using 98 octane - but there are a lot of factors such as the type of motoring, the way you accelerate and brake, traffic conditions, ambient temperature, tyre pressure, even the make of tyre can all make a difference.

I've even had folks swear that a particular brand's 98 is actually better when the fuel they have purchased is actually 95 - in NZ you can only buy 98 in selected cities and only from BP or Mobil.

Where they lying? Nope. They probably did notice something different but it may not have been the fuel...

In a turbo charged car, because of the relative compression due to the forced induction... the higher the octane the better generally as it prevents pinging/knocking or at worse detonation. Detonation is not good... melted forged JE pistons from the race car make interesting paperweights but aren't good for much else.

Interestingly, saw those elemental tin in line fuel conditioners around again too. They didn't work the last time round... can't see how they can now.

There are easier ways to save fuel and increase acceleration... weight saving being a relatively simple way to do so as well as decreasing rolling resistance by ensuring tyre pressures are correct (and increasing life of your tyres)... I did get a few earfuls from one of the drivers that an easy way to save a bit more weight out of the car was for him to lose 20 kgs or so... he didn't like that much.

Guess not everyone can be 75kgs
