Thread: sunoco 100octane in FI Lightning

  1. #1
    Anyone here ever run Sunoco 100 octane in an injected Buell? I heard the CPU has to be remapped if you run better than premium pump gas... But supposedly the computer self-adjusts to how you ride. Wouldn't it adjust to better fuel? Thanks. Joe in PA

    I run 94 when I can, which is a blend between the standard 91 pump gas and 100 unleaded.

    The only real advantage in my opinion, is slightly less ethanol content. Most stations will use 10% ethanol as extender basically in their 87/89/91 blends. Ethanol is not good for our injectors, mileage, etc.

    I have a station near me that sells 87, 91, 94, 96, 98, 100, and 110. I never have used anything over 96, mainly because there is no reason to run anything more than 94 in our bikes.

    I do it for the satisfaction I am getting more gas and less ethanol.

    I ran 103 octane in my R6 every chance I got. The bike loved it.

    My bike has no issues with the ethanol. There is no problems as long as the ethanol content is less than 10%.

    you wont gain any benefits from a such a high octane fuel unless you advance your timing a little more.

    You also have to run a higher compression.

    you may think your buell has no problem with ethanol, but it does. just check your milage of full tank with ethanol E10, and check milage of full tank with 100% real gas , you will see the Difference, also ethanol attracts and holds on to water in the fuel , last i checked engines dont run well with water in the fuel, ethanol can deteriorate some certain rubber hoses (fuel lines), unless the lines are made of Neoprene, which is mostly impervious to degradation by gasoline or other additives such as ethanol. ethanol does help clean some of the fuel system and is what some fuel systems cleaners are made with and all other fuel system cleaners are just Diesel fuel and additives and others are just petroleum Naptha (which is lighter fluid)( this is what most repair shops use because it's quicker also Gunk motor flush is naptha with some additives). But the ethanol cleaning your fuel system can cause the fuel filter to become clogged very quickly. and please by all means
    DO NOT STORE YOUR BIKE WITH ANY E10 OR ANY ETHANOL IN IT.( LIKE WINTER STORAGE)!!!!!!!!!! Because the shelf life of E10 is only 3 months(90 to 100 days) under ideal enviromental conditions. and Stabil only helps for about 1 month then the gas starts to deteriorate again ( actually technically gasoline and ethanol both start to deteriorate from the time they made)
    and yes even that the newer engines are designed to run ok with ethanol (see owners manual), but it does not mean that they will run their best with ethanol or the same with ethanol as compared to 100% real gasoline. also Alcohol(ethanol) makes engines run dangerously hot, not to good an air cooled engines or your leg, especially if the ethanol content is higher than 10%.
    one thing i think i should point out is There is no such thing as pure gasoline, gasoline does contain alot of additives including small amounts of ethanol (usaully less than 1% to less than o.5% ethanol depending on the manufacture as an additive for cleaner also call Detergents.) several good articles and info on ethanol at SAE.ORG ....

    Please read these links about ethanol:

    http://www.fuel-testers.com/ethanol_...ecautions.html



    http://marketplace.publicradio.org/d...ethanol_kills/

    From Stanford University,
    read the first paragragh and Table 1 for future air polution and future health problems, an the increase in carbon dioxide and mathane into the air with ethanol E85
    http://www.stanford.edu/group/efmh/j...perEST0207.pdf

    small engines
    http://marketplace.publicradio.org/d...ethanol_kills/

    And there are a number of problems with an immediate boost in the ethanol blend.
    Automakers warn the higher ethanol blend could boost greenhouse gas emissions, damage engines or disable vehicles

    also point out most states dont require by law to have the gas station to show on the pump how much ethanol is it the gas your buying. so beware of that.
    it is law here in OK.

    i run 92 octane from shell. there is a big sticker that says it contains 0% ethanol. running over 100 octane is just a waste of money in these bikes. well i do love the smell of the race gas but other than that i dont see a benefit.
