HAHAHAHAHAHA... there's a forum for volvos called turbobricks?

Aside from the first two posts (one semi-legit question, one answer) in this thread, that's the only post worth reading!

HAHAHAHAHAHAAHAHAHA

Man, that's good..

lol it is pretty funny, there are some really good people there though. others not so much

Haha, I know nothing of the people.. but the fact that they call it turbobricks bout made me fall out of my chair!

Ok so back on subject. I did some digging again to why the rep at the store would tell me just to run the higher octane fuel in my bike and why it would give me the same effect as many cleaning agents you can buy on the shelf. So I did some asking around and some snooping on other bike forums. It seems that the higher ocatne fuels have cleaning additives in them much like you find on the shelf. and that is why i was told to use the higher octane fuel instead of buying the cleaner. Makes sence!

You know I wonder why I have stored my bike in the past and never had a problem but that was before the ethanol in the fuels , maybe the new gas with the 10% ethanol is not mixing well with the stabalizer. who knows.

Gas with ethanol does not mix well...whether it be with mixing oil or stabilizer...it will eventually settle out. The shell station has more ethanol than other stations around me so I won't get gas there if its for my two stroke or for storage. At school I had no choice..I had to pick up and shake my fiddy to remix the gas in the tank or completely drain it each time I wanted to use it.


Just to reiterate..you're still missing the point. While higher octane fuels do contain cleaning additives the concentration is set to maintain a level of cleanliness. Much in the same way we here in the northeast have warm and cold weather additives to "make cars more fuel efficient" because people warm up their cars before going somewhere or periodically run them during the night if its really cold. The cleaner is a stronger concentration to bust up the deposits in a dirty engine...personally I think they're all a crock..I'll stick to my hand cleaning and rebuilds...the easy way is never the best way...

Im not missing any point. and the carbs are already off so I really could care less about the thread anymore. its not like its hard to rebuild a carb anyways so whatever. 

I could have sworn this was a 3~4 page thread.
Maybe I'm nutz.

Ummm yeah ever heard of carbon build up on the valves. W/E If you don't care 1. Why did you ask in the first place and 2. Why do you keep posting in this thread?  I mean apparently we are all alot dumber than you.

The previous owner of my GS did a rejet, K&N, and V&H and for whatever reason it tends to runs a lot rougher on 87.  I've gone through 3 or 4 tanks of 87 and am going back to 89.  Perhaps the gas containing 10% ethanol has something to do with it.  More likely, it is just jetted a little lean (I swear I'll check eventually )

Any product that claims to clean your engine is largely bullshit.  For the GS, an engine problem due to deposits is so unlikely its not worth worrying about.  In general, engine cleaning products (like seafoam) are for more primitive engines and engines have been used way beyond their typical lifespan.

sorry charlie I dont post at tbricks and havent in a long time there is no point considering I wouldnt get any help from a lot of those guys anyways , usually a bunch of liberals with the wrong idea on life anyways.

But I dont see the need for the post you made. its one thing arguing a point its another posting what you posted, but sense you want some gradification it seems here you go , because I know this is what you are feeling inside:

Yeah, you didn't get good answers over there because your attitude.  Seriously, 'liberals with the wrong idea of life'?  What kind of statement is that?  I posted to point out that you have an attitude that allows you to think that you know the answer, but you don't know enough to know what you don't know.  If you would just listen to answers, and take them all with a grain of salt, you will actually learn from your questions and others' answers.

Want to Clean the Carbon Out? Get a Squirt Bottle full of Water.Pull your Air Filter.Start the Bike and let it Warm up to Operating Tempurature then Spray water into your Carbs.A half a Pint of Fine Mist Per Cylinder Should do it.Follow up by taking it for a Blast down the Road a Few Miles to Burn the Excess water out of your Exhaust.I know Somebodys going to think I'm full of shaZam!. BUT I'm Not. I Have a freind in PA that has Done it all of His life to His Two Strokes (And I know of Others) and unless they are Very badly Carboned up it will Clean everything Clean as a Pin.He is a Certified Mechanic at Just about Everything VW,Suzuki,Kawasaki and Harley.If He'll run it thru his Two Strokes it sure ain't going to Hurt your GS500 4 Stroke since the Mixture of Fuel and Water is Going thru the Crankcase on the Two Strokes.
Also if you want to clean everything out Mix a Tad bit of Car Automatic Transmission Fluid in your Gas.I know an ASE Certified mechanic that Swears by Transmission Fluid.On one of the Boards that I frequent they had Several recipes for Homemade Octane Booster and Transmission Fluid was one of the Main Ingredients along with Rubbing Alcohol, (91% is Great at Helping Disperse the Water that Forms when Ethanol Seperates and Draws Moisture into your Gas) MEK,Diesel fuel or Kerosene among Other things Depending on How much of a Boost you want.

Another way I have found to Get a Little more Omph ut of my Truck by Raising the octane is going to the Station and buying a gallon of 114 Octane (Needed some to jet my T500) My Truck Knocks on Just about anything these days but I was Running Kind of Low on Gas and Had a Little over a Quart of Race gas left and Dumped it in my tank.I then went to the Station andtopped it off with 11 Gallons of 89.I actually got 40 extra Miles out of that tank of Gas and Filled it up at a Station that I knew had Semi Bad gas.At $5.00-$8.00 dollars spent on Enoughoctane Booster to raise your octane to 101-108 your better off to buy 1 Gallon of 114 octane and Dump a little in your tank ever so often.

And it is true I have Gotten Gas at the Station and My truck has Ran Good (Don't Know How it Has 300,000 Miles on it) and a Couple of days Later buy gas at the same Station from the same Pump a few Hours Before the Delivery truck Arrives.The Next Day my Truck will not Run and it is Due to getting what is left in the bottom of the Tank which is Ethanol and probably Water.I bought 5 Gallons Back last Year for my Cousins honda 3 Wheeler he let the Sealed Can set for a week in the barn before he filled his Tank up.One day we had to use it to run Cattle and it wouldn't start.We Checked Everything and when we got to the filter water started Pouring out.We Uncapped the tank and the Gas No longer looked like Gas it looked like Milk.

If you want Pure Gasoline find a Small Independent Service Station that sells Fuel from a Small Independent Oil Company that buys Straight Gas before it is Blended.We have one here where I live that only Sells 100% Pure gas.I'm sure there are Others out there but are probably hard to find.

After reading these posts I think I will stop buying premium gas. Although I feel so good putting the stuff in, thinking it's the best that money can buy, helps keep the engine clean, makes it go faster, extends its life, makes it sound better, etc. etc.

Now I will start saving 30 cents a gallon or whatever the difference is.

you are absolutly right to be putting the cheap stuff in.
i know this has been beaten to death, but i think i can explain it a bit clearer then it has been explained:

Octane is a measurement of the fuels flash point. As in the temperature at which it will ignite.
The higher the octane, the higher the flash point.
This becomes important in high compression engines (usually ones with some sort of forced induction, a supercharger or a turbocharger), because when the fuel/air mix is compressed, it heats up. and when it compresses more, it heats up more, and can ignite solely from the heat generated by the compression stroke, instead of being ignited by the spark plug, like it should be, when it should be. this pre-ignition causes engines to knock or ping, which is BAD.

So the long and the short of it is - if you engine isnt knocking or pinging, you will get absolutly no benefit from higher octane fuel. like it has been said, even if they do put more cleaners and detergents in it, it is in such negligible quantities that it will not effect your engine in any measurable way.

There are exeptions to this with some modern car engines however. My supercharged riviera needs the premium shaZam!, but if i put regular gas in it, the computer is smart enough to detect knock before it is audible, and before it can damage my engine, and the computer automatically retards the timing. so even tho it wont knock with low octane gas in it, you get worse milage and performance when you dont use the premium stuff, because the timing is retarded.

but i doubt there is a single bike engine on the market with a knock retard system.

My manual says to use octane 91 or higher in my 05 GS.

91 listed in the manual is Research Octane Number.  According to this post from another topic, this converts to 87 octane.  There are a bunch of other posts that back this up if you want to search for them

Hm, I don't have the Suzuki manual but Clymer says to give it 87 Octane. Under the seat, though, there's a label that says to feed it 91 octane. Is the label wrong? The bike is a 1995 49-state.

What country are you in?  Europe and Australia use RON, USA & Canada use (R+M)/2.  So 87 in US is the same as 91 in other places.

I don't know a lot about the science behind using different octane levels but I know what my experience is.  My wife has an old 1982 Honda CB750 and if we put low octane gas in it, when it runs it is horrible.  It goes phut...phut..phut...pop! and continues to do that.  there also seems to be a bit of lag when you are trying to accelerate.  When we switch to High octane it runs smoothly.  I figure since it works in her bike to smooth things out, I just use it in my K2 GS as well.  I know that's kind of a dumb logic but I don't mind spending the few extra cents for something that seems to be working. 

Out of curiosity, does high octane gas last longer without stabalizer than low octane gas?  And if you are adding Stabil to a tank of gas, should you add more if the octane rating is higher?  I'm not sure exactly how Stabil stabilizes the fuel so I had to ask.

i beleive, and by all means sombody that knows more correct me if im wrong, that higher octane gas actually degrades faster then lower octane gas (without stabilizer).
