Looks like I will be getting a car (fto) which will apparently benefit from using a higher ron fuel than I currently use in my fiesta :p As I had a fiesta I never bothered looking into what these apparent benefits might be so can anyone tell me what they are as somepeople seem to think it tends to make little to no difference & others say they get more mpg & it is smoother to run etc. What is right :) Just wondering if it does make any noticable difference?
 
Depends what the engine is mapped to run. Most cars are fine with standard unleaded but some (usually turbo's or performance cars) benefit from Super (V Power) Unleaded due to the higher octain.

If I use standard unleaded in my Turbo it detonates (pinks) like crazy. Fill it with V Power and it runs perfect.
 
Personally I think the benefit on such a car will be small and the extra cost spent will be wasted most of the time. In a non scientific way I have not really seen a noticeable difference in fuel consumption between normal and high octane fuels and though I am told these will be it does not become apparent in my trip readings.
 
Unless the FTO has been mapped for 95 ron fuel (i.e. mapped for the UK) then it will be expecting the higher octane fuel of the japanese market. Just use super unleaded (although quality and method of raising the octane rating vary), and you'll be fine :)

You may also get slightly better milage from the super unleaded but only slightly, which may (or may not) cancel out the extra price.

Remember the octane rating is a measure of resisting detonation (pre-ignition if you prefer), and as you car is mapped for the higher octane it should run better and provide slightly more power. Car's mapped for 95 ron will not realistically benefit from using higher octane unless highly tuned already and on the edge of the 95 ron limit.

A lot of peeps say BP ultimate is naff, and prefer v-power, but just see what your car likes (after several fills to clear the tank of old fuel).

To a degree, but using fuel which requires the ECU to compensate is hardly ideal.

Its a bit like using mineral oil. It works but isn't recommended.

Thats a load of carp. All UK cars are designed to run on 95 and will so quite happily. Knock sensors are fitted in case of poor quality fuel so you won't melt your engine if it runs lean. :)

Way to jump to conclusions :)

My car has been specifically mapped for super unleaded. Sure if I revert it back to the standard map what you say is correct.

How do you even know I've got a knock sensor. Many cars that run mappable management don't use them.

Correction, all mass produced UK Standard cars, Yes. But this is probably not a standard car.

What detects the knock then? How does the ECU know when to retard?

Ta, tis an import so yeah is I assume designed (from reading around) to use 100 ron, I was just wondering if it made any real difference....more power is good :p
