Why do people buy high octane petrol?

Until someone plants hard evidence of testing done in a controlled environment with all contributing factors taken out of the equation, I stand by my opinion that there is no need to use high octane fuel in a hot hatch.

Isn't that exactly what the manufacturer would have done - I'm pretty sure they wouldn't just stick 98+ron in the manual and state lose of power/mpg for no reason?!

Nope certainly not, I research buying tyres heavily, as I would never put **** tyres on my car, mainly for the safety of myself and all others who are in my car, and also other civilians and road users.. I have made some errors in the past on tyre choice (due to poor recommendations on another forum), but I always put good tyres on my car.

Why the personal insults now?

I don't see any insults.

It is just your attitude and posting style has lead me to believe you are in this thread simply to justify your own actions (purchasing inferior 95 RON fuel) and to cause issues with people who simply do not agree with you.

This also leads me to believe if you wish to skimp on literally £3-4 a tank of fuel, then you are more than likely to skimp £40-50 on a set of tyres. You just come across having the mindset of a motorist with a limited budget who cannot afford to run the vehicle he has got correctly.

This is all speculation though. That is why I asked in my post you have just quoted.
 
Ethanol RON raiting is 109 isnt it so the more they keep putting in the fuel the more power you could make on it. People in countries with E85 swear by it as you can have a super aggressive map on your car to take maximum advantage of the high RON rating.
 
I am still amazed that the focus ST driver is running his car on a fuel other than that which is recommended by Ford in the owners handbook. It's like being advised by the doctor not to have a bare knuckle fight with a polar bear, ignoring the advice and getting your face ripped off in the process.

*This may be a bad analogy
 
BRB, i'm going to argue with CERN about particle discovery.

Now i know nothing about this subject but that won't stop me making an arse out of myself in the process...........
 
Wow. I have been running my Fiesta ST solely on V-Power for the last month and a bit and have definitely noticed a increase in MPG, much smoother engine and better acceleration.

Using V-Power has resulted in my MPG being a lot more consistent also. I'm using an app on my phone to log miles to a tank and on normal fuel it would fluctuate from 26-32 MPG but with V-Power it's been 33-34MPG every time.

You should be using V-Power in your Focus ST. Run it for a good 3 tanks worth and then continue to do so as it's much better in the long run.

Even the direction you drive can have an effect - I am never able to acheive peak fuel economy when driving down the M5/A38 when compared to driving up instead.

:eek: Glad I am not the only one that finds this, thought I was going crazy :p

I recently read that filling up a few tanks of 97 in a 95 designed car can be good for the injectors and generally clean things out, resulting in improved mpg in the long run (was an AA article in a local paper). Is this true?
 
in regards to shells diesel vpower i have to admit having switched between tesco derv and shell vpower(depends where i'm nearest when i need to tank up) i do notice that my taxi runs better on the shell vpower and does increase the fuel economy

last year i ran exclusively on vpower derv for nearly 5000 miles and noticed a solid 3/4 mpg difference in economy wheras the stock shell diesel is a neglible difference from tesco derv.
that said my remap gives me the same kind of gains again on top of that. in addition to the mpg i've also noticed the 1.9cdti lumps (well the few i've played with and know well) do run quieter and smoother on vpower derv than normal fuels. the car seems more responsive and generally seems to pull ever so slightly better.
 
My S-Class runs fine on poverty fuel. My MX-5 runs like a bag of **** on anything but V-Power.

Speculating I would equip my car with inferior tyres is an insult.

Your education must be lacking severely. How do you come to the conclusion I am a skimp? Because I choose to fill my car with normal Shell fuel, this has nothing to do with the fact I am poor or have a limited budget whatsoever. Another insult.

I choose normal Shell fuel, because I have yet to be proven by facts that the more expensive fuel is going to do what it says on the tin.

IMO these manuals you speak of, given politics etc. I wouldn't put it past the likes of Shell, BP etc. to be paying money to manufacturers to print these things. But hey, this is just a presumption of a fact I am unaware of.

I stand by my opinion that there is no need to fill with high octane fuel over normal fuel on a car with no significant power output, nor is it imported from a country that only sells high octance fuel, and you haven't gone to the expense as to pay for your car to be mapped to a specific fuel like others in this forum.

I am more than valid to have these views, and until you can belittle me with hard evidence, please avoid the insults my "inferior levels of income"

To the Roflcopter, goodbye
