I got this reply from Suzuki - below. Still haven't tried it and no idea if it'll be any good. May be different results in the Ignis to other Suzukis as M15A is tuned for 98ron and has a more modern set up than say Swift gti.

If you have any experiences of the new fuel in an Ignis post 'em here.

"Suzuki listed Ignis Sport as a model not recommended to run on
ethanol blended fuel.
However, this was based on an understanding that blending would be
confined to the high volume fuels such as regular ULP.
Provided that the RON requirements are met (98 RON) and that ethanol
content does not exceed 10% then it is permissible to use such
a blended fuel in this model."

I ran a tank of it in my Ignis. There was a definite power increase, but it was only minor (about what you'd expect from 2 octane). The ECU definately knew how to deal with it (probably because that's what they run in Japan).

I didn't half blend it either, I had the tank so empty that the fuel was cutting around corners before I filled up on it. I've been told that ethanol won't harm the engine unless it's over 10%, and apparently 5% is a good blend (from what I hear).

I've tried it too - definite improvement
Worth the extra couple of cents

I went to Ferntree Gully (it's still a 25min drive!). The attendant liked my Suzuki watch :)

Definitely has more urge as you pass 4000rpm in 3rd which is where the Iggy produces max torque.
I'm impressed!
Now I'm curious to see what going back to a 98RON fuel will be like...

Filled up with 98RON fuel recently
There is definitely a performance loss compared to 100RON
I'll be sticking with Optimax Extreme in the future

I've auctually switched back to bp ultimate because although the shell extreme has a higher octane , it has felt a bit rough and been backfireing a little bit , most probly due to the ethinol.
Where as the ultimate has felt more stable and cleaner through out the rev range.

Mine's the complete opposite
The engine' heaps smoother & definitely revs better
My only mods are a K&N panel filter & cold air intake

RON (Research Octane Number) is merely a measurement of "anti-knock" that the fuel has. The higher the octane rating of the fuel, the more energy is needed in order for the fuel to combust. If fuel combusts early, it can cause knocking which you don't want to happen.

It's common myth that higher octane fuel will increase its performance and/or lessen its fuel consumption. Almost all engines perform best when using fuel with the octane rating they were designed for and any increase in performance by using a fuel with a different octane rating is minimal.

Only with high performance track and race cars that produce in excess of 400-500bhp would you really see a difference.

On the Ignis Sport, anti-knock sensors are built into the control systems whichy dynamically de-tunes the engine if using a lower grade fuel by increasing the fuel-air mixture and retarding the spark. The opposite is also true of a higher octane fuel.

The car is designed for 98RON fuel. Run it on anything more and any effects you think you're seeing/feeling are purely a psychological placebo effect.

I went through this myself before someone told me it doesn't really make a difference on normal road cars.

While your statement is true i have seen dyno sheets of different fuels used on a test mule and some fuels have shown an increase of power,when boost 98 was introduced last year it was seeing a regular increase of a couple of kw on many Ls1 powered cars that were tuned for 98 ron petrol over the more common Bp ultimate.

And thats why i said the effect would be minimal. A couple of kws cannot be noticed by simply driving the car, and such trivial low increases can be easily achieved by lowering the air temperature in the garage you are dyno-ing the car in. The difference is even smaller than turning the air-con on and off in the car as you go along which sacrafices about 4 or 5 kw in some cases.

Using a higher octane fuel is just not practical for the car, nor for your pocket in the long run.
