Special gasoline

[seeberluca]

I was out of fuel, and the gas station , today is monday, too. I had no way to wait for the big tank station refuel , so I decided to buy the UGL 100 gasoline just for this time.
Can this gasoline affect something in the engine, or will it just let me run faster?

I don't have much information about that fuel but I'll guess that it's 100 octane fuel.The bike is designed to run on 87 octane....
Higher octane fuel is engineered to operate in higher compression engines so you should see no benifit or damage from using it,other than the increased cost.
Lower octane ignites faster than higher octane.You would use the higher octane if you have "pinging"..a pre-ignition knock.http://science.howstuffworks.com/gasoline3.htm

This is my guess....unless this is a special blend of fuel.

At the moment it was the only one avilable, anyway here in Italy the minimum octane you can find is 95. Since now I did not feel any difference with this "special" gasoline but the price 2.6 $ per liter

You should not notice any difference, the new gas is capable of producing more power if you modify the engine to take advantage of the higher detonation levels (Run higher compression, more advance on your timing!!). As I doubt you have changed anything on your engine, the bike will run fine, you will not harm anything, you just spent a bit of extra money unnecessarily..

Yes but it wasn't unnecessary. It was all that was avaiable at the time he was on empty.He didn't have a choice.No harm done to the bike,just the wallet.

Actually, you'll get a bit LESS power and mileage out of the higher octane fuel. Without being able to alter the compression to take advantage of the higher detonation threshold, the higher octane fuel will run normally (albeit producing slightly less power) and do no damage whatsoever except to your wallet.

Ok thanks for the answer,
the only positive consideration is :
very high gasoline cost, no more then 110km\h speed.
result?
18.9 km per liter and more safety

My daily driver is a large truck with a V8 engine in it. With today fuel prices, I have learned to drive VERY gently - very gentle presses on the accelerator, try to use as little braking as possible, plan ahead, so that you can maintain momentum, no excessive speed. I can get as low as 8-9 mpg in it, I can also get as high as 23-24 mpg if I really try.

That's also the reason I ride my motorcycle more than I drive my truck.

I'm agree with you, but if you consider we have the EURO not DOLLAR and I have to pay 2 dollars and a half per each liter of gasoline, I should ride a bicycle to save money.

Wow! that's $9.45 per gallon! And we complain when it goes over $4.00 here in the states!

[virgilmobile]

Don't forget...He has euros....conversion...1 euro = $1.29 US dollars.
4 liters is just a bit over 1 gallon.....That makes it around $12 US dollars per gallon.

This is a little bit too much. 2.5 $ per liter is after the conversion euro/dollar ( one liter of gasoline costs around 1.93 euro so 1.93x1.29=2.5$ than 2.5 x 3.79 ( litres per gallon)= 9.47 $

Sometimes the higher octane fuels, I'm thinking Shell in the UK also have cleaning agents in them. I've heard it suggested that two or three fill ups of that every now and again can clean the engine.

I remember a shell additive attacking some valve seats in GM engines in about oo 83/84.

I'm told that goldwings don't like fuel with any methanol or more than 5percent methanol?

I just filled up @ 3.92/gal on 100% gas. No ethonol. Reg. 10% eth. gas is 3.49 here. I'm getting 40mpg at last ck. It could be all in my mind but throttle feels more responsive on 100% gas. Hmm wonder if there's a NAT gas conversion for bikes yet?
