    I lust learned about this site and their app yesterday

    Yeah Jersey does have cheap gas but they won't pump gas into a bike and I'm cool with that last thing I want is some kid to pump gas and spill onto my crotch. the no E85 thing sucks though.

    Check my post in the "extended range" thread and find the ethanol free national web page: add 10-15% MPG AND keep your fuel internals 100%...

    You have 86 registered stations in PA

    http://pure-gas.org/index.jsp?stateprov=PA

    Now, here is part of the deal there: SOME of the stations only have a higher eth-free Octane like a 91-94 AND it maybe 50-60 cents per gallon more. Don't let that deter you, keep searching.

    We found a station near us that's 89 octane 100% REAL FUEL , and it's only about .10 cents a gallon more.

    Here's part of the ethanol secret that big industry don't want you to know; it literally evaporates in higher temps.. So, in the summer time when you might commute to a day job, park your bike outside in the sun for the day, your newer bike with a decent vent system is literally blowing off ethanol just sitting there in the sun. It's stupid money...

    I'm finding that the one station near me is the higher octane like you said but it's also leaded, is there a risk running leaded gas in a unleaded gas engine.

    Yes, your spark plugs can "Lead-up" if you use leaded gas in an engine designed for unleaded fuel. You'll need a higher heat range plug designed for leaded fuel if you want to run it.

    As far as ethanol content goes. I keep several of these little tiny bottles in the rear cowl compartment. http://www.starbrite.com/item/star-tron-shooter-1oz-super-concentrated-formula?category_id=586 Before I fill up, I dump one in. Problem solved.

    You guys can legally run leaded petrol on the road?!

    Not where I am. They require it to be poured into a container or a none dot vehicle on a trailer

    Generally speaking; No. Running leaded gas is illegal in all 50 states... Unless you have a registered classic or historic vehicle which cannot or should not be converted to modern fuel.

    I use 91 octane & it's the only ethanol free fuel in my part of the woods...

    I've been experimenting with Regular (87 - 10% Ethanol) and Premium (91 - Ethanol Free) the past few weeks. I can't be fully sure yet as I haven't put on enough miles with both, and conditions (weather / wind) have been volatile. That said, so far the trend appears to be that the Premium (91 - E-Free) seems to have had a drastic effect on my fuel economy. I've logged almost to 3,000km's already this year thanks to an early spring. :)

    To qualify my findings - I am 230M (750 ft) above sea level. Temperatures have fluctuated between -2*C (28*F) and +22*C (72*F). Winds have varied between calm to gusts up to 60kph (38mph). The bike is an '02 VTEC.

    My worst tank so far was 7.45L/100km (31.57MPG) and my best at 5.5L/100km (42.66MPG). I suspect my current tank is going to surpass my best - I'm estimating I'll end up near 5L/100km (47MPG)

    I have no doubt being a higher compression engine (11.6:1) that the mid or higher grade will return better mileage and performance. Whether or not the difference is cost offsets the gains or not remains to be seen.

    Some additional food for thought (and potentially opening up some religion here ... lol):

    - Running Ethanol Free fuel should help keep our already "running hot" engines a little cooler. Ethanol does burn cooler, but it causes the engine to run leaner, and as a result, potentially hotter.
    - Higher octane can withstand higher compression before it detonates, this is why some lower rates fuels can cause knocking (detonation)
    - Ethanol became more increasingly present in fuel in the mid 2000's. For some of us with older VFR's this could make a difference in how it performs on an E Fuel vs. E-Free Fuel.
    - I wonder the relationship between a hotter plug and fuels with higher octane and the results?

    This is the best description I have found. So when discussing octane used for bike or whatever one should add what country or rating is being used. Without it, it creates a lot of confusion.

    Measurement methods




    Research Octane Number (RON)

    The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane at 600 rpm.

    Motor Octane Number (MON)

    Another type of octane rating, called Motor Octane Number (MON), is determined at 900 rpm engine speed instead of the 600 rpm for RON.[SUP][1][/SUP] MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern pump gasoline will be about 8 to 12 octane lower than the RON, but there is no direct link between RON and MON. Pump gasoline specifications typically require both a minimum RON and a minimum MON.[SUP][citation needed][/SUP]
    Anti-Knock Index (AKI) or (R+M)/2 or PON

    In most countries, including Australia, New Zealand and all of those in Europe,[SUP][citation needed][/SUP] the "headline" octane rating shown on the pump is the RON, but in Canada, the United States, Brazil, and some other countries, the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI), and often written on pumps as (R+M)/2). It may also sometimes be called the Pump Octane Number (PON).
    Difference between RON, MON, and AKI(PON)

    Because of the 8 to 12 octane number difference between RON and MON noted above, the AKI shown in Canada and the United States is 4 to 6 octane numbers lower than elsewhere in the world for the same fuel. This difference between RON and MON is known as the fuel's Sensitivity,[SUP][4][/SUP] and is not typically published for those countries that use the Anti-Knock Index labelling system.
    See the table in the following section for a comparison.

    So just for an example: 87 octane in the USA = 92 octane in Europe
    89 octane in the USA= 94 octane in Europe
    92 octane in the USA = 97 octane in Europe

    My understanding is that the (6th gen) fuel system was not engineered to hold or use ethanol for extended periods. Missouri state law (a few years ago) mandated a 10% ethanol blend in 91 or lower. Thankfully BP has the ethanol free 93. My weed eater and lawn mower get 93 as well.

    I thought I read an article on AsphaltandRubber.com explaining that E-fuel damages some fuel systems. I'll see if I can find it.

    I put fuel stabilizer in at the same time I ad 1 gal of gas to tank-I only go 10 miles that way the bike will last another 30 years.:stickhorse:

    After reading this thread i decided to try premium today.
    The only change i noticed between regular and premium gas is that premium costs more.

    95 gasoline is my choice. I had big trouble running gas with 5 % ethanol mixed in it. Gummed up the carburetors and damaged o-rings.

    Nice Super Magna, Hondaman57!

    I've only ever heard of e-fuel gumming things up if you've been running regular fuels for a long time and your system is dirty ... the ethanol cleans it out ... this was a big deal when we used to have Mowhawk gas stations. They were one of the very first adopters of e-fuel here.

    Growing up, I was always taught to stay away from their gas unless you had a new vehicle and you kept using it. Don't know how much of that is fact and how much is fiction though.
