I notice a huge difference when using injection cleaner: IT STINKS

I got my injectors professionally cleaned at around 55k km (44k by PO). They were not to bad. Might be because I had used injection cleaner and only filled with premium.

For the money I spend on injection cleaner I can upgrade to 720 liters of premium ethanol-free petrol which is more than enough for 12k km riding at my fuel consumption

( QUOTE) As I understand it, Octane is only a fuel stabiliser used to stop pre-ignition in high compression engines. It adds nothing to the flame front itself,

The Octane number RON and MON (lets not go there) is a number given to indicate the resistance of the fuel to detonation the additive to slow the burning of the flame front can be a multitude of chemicals Benzene , Toluene or ethanol and the like, you are right BatKwaka the additive adds nothing, it slows the process and stops detonation there are high speed films of the flame fronts in an internal combustion engine and it is a burn across the top of the piston( albeit in a millisecond ) not an explosion as would seem more logical. The pinging sound from detonation is actually the piston rattling against the cylinder wall (ouch) that's why too much of it catastrophically destroys the piston, anyway there's my ramblings for the day that's the good thing about forums you can disregard people like myself that don't make sense,

It probably does some good and I only ever buy it at 80%+ off because as you say the cost benefit ratio at full price would not add up and you would probably be better running the so called "clean Fuel" though the engine. I put a capful of Castrol R in the tank every now and then just to remember my youth with a screaming two stroke, now that stinks in a whole different way

One person's stink is the other's perfume.

I love the smell of skunks

I use the 97 every other fill up..
Saves me putting injector cleaner in every so often.

Yep and that was why I used it as well Simon, found it worked better than injector cleaner due to its additives.

H2 needs premium.

GSX14 was set up on the dyno and mapped with BP98.

I normally chuck it in everything. The internet experts tell me I'm wasting my money but my stuff go's OK and I've never had fuel related problems so I'm not fussed.

I ride and drive a lot of different vehicles, the exception to my fuel rule is my Hilux.  It's new(ish) but runs very well known and proven 2.7 petrol. Much as I try I genuinely can't tell any difference between any grades of petrol in it, it's just a workhorse that go's. I ran it on 98 for a month, ran it low and then ran cheap low grade fuel and couldn't tell!

To complicate things, at least in Germany, we have winter-. summer-, and between season-petrol. Main difference is vapor pressure which gets reduced by 1/3 in summer petrol to prevent bubbles in the fuel lines. The winter petrol is easier to ignite. I am not aware that there is anything in the engine management to adjust for that.
