    High compression engines require high octane fuel!
    My sprint gt enjoys a 12-1 compression ratio....use high octane .....please!

    So you hear it pinking when you use regular fuel?

    Every 5th or so fill up I use premium
    For its enhanced cleaning properties

    When I bought my Speed Triple in the summer, it had done 11k miles over 7 years, it was running quite rough with uneven tickover but after 2 or 3 tanks of premium it was very smooth, like it had just been broken in.
    I notice the popping on the overrun is more noticeable on premium, so something is happening

    I thought I read somewhere that in the case of the 865 EFI engine it runs worse with 98 octane. Don't waste your money! :cool:

    It’s regular fuel for all my bikes and never had a problem.

    Sometimes Shell regular or even Morrison’s regular, it all depends on which way I’m going on a rideout.

    depending on the ecu the engine has.......probably not...the more cylinders, the more detonation....that is what creates the ''pinging'', Lot of good posts here......some not so much.......nothing wrong with this one, :)

    The BMW minimum recommended fuel for my R1200S is 97 RON, so I was a bit concerned touring Scotland a few years ago, when I was forced to put the normal stuff in (will it like even start???) or run dry. But I didn't notice any difference at all in performance or consumption. Similarly, heading down through France to Spain the next year, it ran mostly on lower grade fuel, with no problems at all. I stick to the recommended grade where it's available, but don't have any worries putting common or garden in if that's all that is available.

    I do agree that there is a noticeable difference in feel, with all the bikes I've owned, on cool, fresh days. I much prefer riding on cool days. The engine is much more eager and crisp. I always put that down to more oxygen in the denser cool air.

    One thing to remember is that "super" fuel does not go off the way normal fuel does. So it pays to put a bit of super in before winter if laying the bike up. You real bikers can just ignore this post.

    Good point I don’t use super market petrol but do use their diesel in car with millers additive,yes shells dearer for petrol but for bike anyway it’s worth the extra imho.

    I'd agree with this. As I understand it, the higher ethanol content in the cheaper stuff can cause 'varnish' like deposits in fuel systems and carbs if the fuel is left unused for more than 3 weeks. So for everyday/regular use, cheapo is probably fine. I use premium as I'm a wet blanket fair weather Sunday rider and hence, my trusty lawnmower gets premium as I hate cutting the grass. But when I do, it seems faster...

    Just to confuse matters further, it depends where you live.......
    Last time I checked the south west is one of the several areas where buying high octane fuel doesn't get you any less ethanol content.

    The myths abound.......

    All UK petrol is brewed to a common standard EN228 (up to 10% ethanol) and the different retailers’ tankers load from the same gantries. The real difference is in the premium fuel additives which contain more octane boosters, detergents and lubricants of pretty theoretical benefit to a low mileage vehicle without the necessary sensors and ECU.

    I agree with you, I would say if it is a better fuel you would get better mpg for a start which is the only way I could justify the extra dosh, if you are not getting anything out of it why bother when the prescribed fuel is quite ok ?

    I work on the tankers, and on Shell, I can tell you that what kind of fuel you’re getting depends on where you are in the country (with regard to normal fuel) There are only two places that provide V Power, Grays in Essex and Shells refinery in Stanlow, so that has always been as it should, but after the Coryton refinery closed, we’ve been getting fuel from all over the place in the South East. Proper Fuel Save fuel has only been available in Grays for the last few months. But stocks are still topped up with generic fuels from Navigator terminal in Thurrock, and from Esso terminal in Purfleet. As for supermarkets, again, depends where you are. I fill up in Asda, they get fuel from Esso, or did till recently, the same goes for the others, depends where they can get the stocks from for the right price. I personally save my cash and get 91 RON.
