    Which do you use?
    I've one bike which seems to prefer regular,and the mechanic said to use regular unleaded, but my other (r1200r) runs better on premium, or at least seems to.
    Any particular preferences?

    I haven't seen premium at the pump in probably 10 years?

    Higher octane than the manufacturer recommends is just wasting money.

    I don't think there's a mass produced bike made that needs more than 95, which is standard unleaded. In US and some other places you can get lower grades than that.

    In Cavan there was a great fire / Judge McCarthy was sent to inquire / It would be a shame / If the nuns were to blame / So it had to be caused by a wire.

    Most modern bikes are designed to run on the lowest common denominator rated fuel, so paying extra for 'premium' - if you can find it - is just a waste of time imho

    Ode To The Motorist

    “And my existence, while grotesque and incomprehensible to you, generates funds to the exchequer. You don't want to acknowledge that as truth because, deep down in places you don't talk about at the Green Party, you want me on that road, you need me on that road. We use words like freedom, enjoyment, sport and community. We use these words as the backbone of a life spent instilling those values in our families and loved ones. You use them as a punch line. I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the tax revenue and the very freedom to spend it that I provide, and then questions the manner in which I provide it. I would rather you just said "thank you" and went on your way. Otherwise I suggest you pick up a bus pass and get the ********* ********* off the road”

    Can't remember what they call it in the North, but in GB, normal 95 RON is called "Premium" and 98/99 RON is called "Super".

    They just use a different method for calculating the octane. There's is quite close to ours

    Yeah their numbers are different, but our 95 is the lowest here, their equivalent to 95 is often not the lowest.
    I seem to recall seeing 91 or 92 in Germany years ago, too. It was a small bit cheaper.

    My last car had a use 98 RON on the fuel lid. Because we are in Ireland it never got it and ran fine but I'm sure that if it got 98 RON it would have performed better. The ECU senses the fuel and adjusts the engine for it. So an engine designed for 98 will run fine on 95 but will lack the performance it's designed to have, will a person on the road notice is doubtful. If the engine is only designed for 95 then you are burning money putting in anything else.
