Anyone noticed any performance difference between 'premium' & 'super' unleaded?

I run premium but, have run regular, and no, can't really tell much difference. I'll stick with premium when I can. |

On my F800 and Aprilia Tuono I don't notice a performance difference but always run the Shell or BP Super Unleaded (98 Ron) because on the: Growning old is compulsory, growing up is optional |

I think it the long term the engine and injectors will be much clearer with a super-unleaded fuel, so anyone who likes to hold onto their bikes for a few years will likely see a benefit over the bike’s lifetime but I’m sure there’s no performance benefit between the 2 grades on regular fill-ups |

Zitat von Boxerboy im Beitrag #9 It would be nice if "Premium" fuel didn't have as much ethanol as do lower octane fuels, but that certainly isn't the case in most parts of the U.S. Almost all of our fuels have at least 10% ethanol, no matter what the grade and now the government wants to increase that to 15% to keep the corn producers happy. Also, the gasoline refiners all say that the same amount of detergents are used in all grades of fuels, as required by our clean air and vehicle pollution control warranty regulations. Fortunately, there are fuel stabilizers available that will help with long-term fuel storage in gasoline engines. I have a friend that has 24 motorcycles, some of which don't get ridden very often and he says these stabilizers work fine, even with smog gas.

Zitat von Mr. 36654 im Beitrag #5 Yep, using a name doesn't tell us what gas we are talking about. Different gas companies use different names and different states or countries use different names. In Iowa Regular is 87 AKI without ethanol. Super Unleaded is 87 AKI with ethanol Premium is 91 AKI without ethanol Can't remember what 89 with ethanol is called.

Zitat von Mr. 36654 im Beitrag #5 OP is using UK terms - we have some fuels with higher RON of 97 or above which are designated super unleaded. Our most basic fuel is called premium unleaded and this is 95 RON. We also have some fuels such as Shell V Power, Total Excellium, Tesco Momentum, BP Ultimate, Texaco Supreme and Esso Synergy Supreme+ that claim to be super unleaded with extra performance due to superior additives. Some of these claim a RON of 99 in the UK and I have seen RON 100 on some pumps in Germany on Aral(BP) pumps. I am quite cynical about the benefit of the latter to vehicles that are designed to run on the basic 95 RON fuel that confirms to the relevant European directive and equivalent British Standard. Incidentally, my S1000XR actually specifies the 97 RON fuel. I didn't know this until after I had filled up for the first time with 95 RON when I read the manual. I have since filled up with the Tesco Momentum fuel. Just like on the RS, I can't really notice the difference in performance. I don't record miles per gallon or miles per tank so I have no idea if there is a difference in consumption. I will stick to the 95 RON for the RS and the >97 RON for the XR as these are the fuels specified by BMW and the ECUs etc will be set up to use these fuels. |

Zitat von Boxerboy im Beitrag #9 does your comment apply to the bog standard super unleaded you see at supermarket pumps or the over-hyped super duper fuels with allegedly superior additive packages i.e is it the higher RON which is what makes the fuel super unleaded as far as the CE standard is concerned, or the really nasty, toxic chemicals added that produce the effect you perceive? |

10% ethanol fuel produces a mixture that is 4% leaner than a pure gasoline mixture. This produces greater combustion chamber heat and a throttle response that is less than linear. What is more, corn is a poor choice for the production of ethanol as it is more expensive to make than gasoline. Why does the government do this in view of these negatives? It's strategic; they wish to maintain a high farm production capacity at times when things like corn aren't selling...
