What grade gasoline do yall use in your bikes? A buddy of mine said its best to use super unleaded in a motorcycle. Which I dont have a problem with since it is such a small tank. But if its ok to use regular than thats what I would use.
user manual says regular (87octane on the M+R/2 scale)
Use regular. If you read your bike's manual you would see thats what it recommends.
Your buddy probably has a super-sport or some other motorcycle with a high compression ratio that needs the extra octane in higher "grade" fuel to prevent pre-combustion. The gs is low compression and is perfectly happy with regular fuel.
compression in these bikes is 9:1, i believe. This is at the upper middle end of typical. You will never get preignition from improper octane rating.
use regular. it will save you money.
Raced the bike on regular. It's better gas than premium anyway.
87 octane. I can attest that on my bike when I ran it on 89 (because 89 is cheaper then 87 in Iowa) the bike had erratic idle.
Only problem with gas now days, is that the ethanol thats in it... Good lord. We pay almost $4.00 a gallon yet its alright to them to put 15%+ ethanol in our gas... And the ethanol destroys engines over time.
Not to start anything. but did you know almost 80% of our gas that we use in the states actually comes from THE STATES. the 20% is imported.. so what does that tell you? That the "war in the middle east" is a bunch of BS on gas prices.. And it's just giving them a reason to raise the prices. Just my 2 cents
like J_walker said just use 87 w/o ethanol. I've tried putting 91 w/o ethanol but i didnt notice a difference
Thanks guys. I figured it would be regular fuel. Blue smudge if I had a manual I would read it. Plus I have all you fine people to help me out.

My advice would be get fuel from a place with a high turnover of fuel. Fuel is like fruit and veg, the fresher the better.
I personaly would run 87 all summer. However a few tanks befor storage I run 91 to get the 87 out of the tank. I also put fuel stabalizer in just as a precaution. With 87 in the tank for long periods like winter storage it starts to smell like varnish and can clogg up the jets. With 91 and fuel stabalizer its good till spring. m2c

87+a fuel stabilizer (Stabil, or Seafoam) will hold just as well as 91. Not sure why you choose that over 87.

Only because storage can be a very long time. You are prob right about the 87 with stabalizer but I have found that my machines start easier and run better on inital start up with 91 and stabalizer.

Regular is not BETTER than premium, it's the correct selection for the GS engine. It's not a high compression engine, and using premium fuel does nothing to help it. Technically you aren't hurting it either, just wasting your money.
Thanks for all the advice. :cheers:
Regular is better than premium, for our bikes.
An engine designed for a high octane gasoline will experience per-ignition or detonation when run on a low octane gasoline... A lot of cars and a few bikes have knock sensors to detect early signs of pre-ignition, and retard the intake timing to compensate, but in doing so will suffer a noticeable loss of power and fuel economy. Vehicles that take premium and do not have knock sensors will suffer damage, and reduced performance.
However, octane enhancers tend to increase the temperature required to ignite the fuel, slow the flame propagation speed, and don't tend to burn as well as more pure regular fuels.
Since the GS runs just fine on regular, you're paying more money for lower performing fuel. If you want to take advantage of premium fuels, you could advance your ignition timing, or install higher compression pistons. In doing so, you'll generate better power, and/or better fuel efficiency.
Premium fuels may have extra detergents such as Techron or V-power, but those don't actually benefit performance unless your engine is in need of a very good cleaning.

Actually detergents vary more by supplier than between grades. Most oil companies use the same additives in all grades of fuel and there is an EPA mandated minimum in the USA. Toyota is part of the group of 6 auto makers that recommend using Top Tier Gasoline in their cars which contain more deposit cleaning additives in all grades of fuel. Here's a list of Top Tier Gasoline suppliers:

87 Octane is what is recommended by Suzuki, 87 is what I use. Another thing to keep in mind is the freshness of the fuel. Fill up at a gas station that does a high volume of sales to make sure you don't get old fuel (or worse, water contaminated fuel). And more people buy regular gas than premium so it tends to be the freshest :thumb:

it's based on science.
higher octane burns slower than lower octane.
putting 93 in an engine designed and tuned for 87 effectively retards the timing
more unburned fuel comes out in the exhaust, hurting mileage, power, and emissions.
you can go ahead and spend your extra $.70 per tank for worse performance... i'll save money AND have a better running bike.
My owner's manual states that the bike "requires regular unleaded gasoline with a minimum pump octane rating of 87((R+M)/2 method)." YMMV but I have found that the bike runs better and I get better mileage from higher octane. Higher price with higher mileage vs. lower price and lower mileage, cost wise it probably works out about even. BTW it will run fine on 87. Use what makes you feel good :thumb:
I always use 91 in anything but a car or truck, I dont have a lot of experience in bikes but in sleds and atvs if you use 87 you always have problems with the gas because it has ethenal in it. I was told by a reputable mechanic that that you should run a tank of 91 octane once or twice a year in any car with fuel injection. this came about because my wife's car had her check engine light come on and i took in to the dealer. (her car is a 2008 pont G6 with under 55,000 miles.) they said that one of the injectors was wasnt spaying wright that it might be plugged some what, so they wanted to run a fuel treatment through it. I asked how much it costs, they said $200. I asked what it was, they said that they would plug the injectors in to a machine that had a cleaning solution in it and run the car for about 10-15 minutes and it would clean of the injectors. i asked what is the difference of me putting premium gas in the car with a can of seafoam. he said that it was about the same thing. so thats what i did and the light went off. it was after this that i asked my friend who told me to do the one tank of 91 octane a year, because gas with ethenal doesnt burn as clean as gas without it. Just what i have been told, take it or leave it.
i know the gs isn't FI but either is my atv or sled, and it always seems to run better.
Quotehigher octane burns slower than lower octane.
Thats not accurate.
Octane rating, as we know it is nothing more than this: A fuel's resistance to ignition through compression. Higher octane fuels cost more because we are not allowed to add lead compounds like T-E lead to gas anymore, and lead substitutes are not cheap.
When octane boosters are added to fuel they literally change mixture makeup of the fuel, displacing more easily ignited HCs.
Hydrocarbons in low octane fuels have many weakly bonded hydrogens These are the ones that combine quickly and easily with oxygen and produce fire when heat is added, even just heat of compression.
High octane fuel has fewer loose hydrogens, and is harder to ignite. It burns just as fast as regular fuel. Its not like diesel fuel.
Quote(high octane fuel) effectively retards the timing
This isn't true at all. All the fuel ignites when the spark plug fires. Thats what its there for.
Quotebike runs better and I get better mileage from higher octane.
This is questionable.
Higher octane fuel was created to appease the higher compression engine. Not the other way around. Because higher compression engines produce more power by increasing fuel temp before combustion, which leads to a more complete burn, we needed a fuel that would not ignite before it was supposed to. (knocking) Higher octane fuel actually contains LESS useful hydrocarbons per unit than regular. Thats just the way it is. It may burn smoother (more controlled burn), which is the meaning of the rating, but not with more energy.
Our engines may not burn high test as efficiently because they don't create enough preignition heat to effectively loosen the bonds in the tighter hydrocarbons composing that type of fuel. (Additional Heat = catalyst for reaction with oxygen.)
That doesn't mean that high test will give you worse mileage, you will use fuel at the same rate, your jets and intake will not have changed - That is what determines your fuel usage. (and your wrist.)
I dont know the vapor pressure differences between the grades of gasoline, maybe better fuel milage could be a product of the vapor pressure of high test being lower, thus, it atomizes less readily, and your carb uses less of it by default. I'll do some more research if anyone cares.
im learning new stuff! by all means , keep researching.
I did a bit more research as a result of this thread.
http://e85vehicles.com/e85/index.php?topic=1893.0
http://speedtalk.com/forum/viewtopic.php?p=84096&sid=a573a6000ba297a30a99964c0a32efb8
Short version is that flame propagation speed has no relationship with octane rating - different mixtures will have different flame front speeds - sometimes the low octane will burn quicker, other times the high test will burn quicker. One of the links above compares the flame speed of ethanol to normal pump gas, and shows that the flame speed of ethanol is much faster than gas despite the higher octane rating. My previous comments about flame propagation speed were made in error. :(
Regarding a post above: you're likely to have more ethanol in a high octane gasoline than a low octane gasoline. Ethanol has a very high octane rating, and will tend to improve the rating of the gasoline it's added to. It did after all, replace MTBE as a common octane enhancer.
You're right burning1, ethanol is a pretty common octane enhancer, which kinda blows for people trying to get away from it.
Lower grade gasoline, with all its sensitive HCs tends to explode more than burn even at standard pressure, and that erratic nature does slow down the flame propagation because the looser hydros ignite first. Expansion pushes everything around, and then you have to play flame-a-chase trying to ignite more stubborn molecules.
Premium grades will have a more uniform mixture and burn radially and evenly from the ignition point.
There is no standardization on the mixture of gasoline that makes up a given octane level, but there are mixtures that are expected to work. Samples are taken pretty randomly, I believe, to test octane rating. If at all. I imagine the batch of hydrocarbons varies in every truckload delivered to the gas station.
This ads another problem to the knocking issue - the L/O gas is also not burning the way the crown/head interaction wants it to. And ignition may be completely in the wrong location in the cylinder when it pre-ignites.
Actually, the wikipedia article has two HC structures next to each other with respective ratings, and if you guys like chemistry, you can see why they are rated differently.
Theoretically speaking, you could get better gas mileage with higher octane IF it enhanced the performance of the engine.
Consider that, as Funderb said, the fuel consumption is determined by two factors: percentage of throttle and size of jets. The relationship between the jets and throttle percentage is fixed.
Now, consider this: fuel efficiency is not the same thing as "MPG" yet they go hand in hand - why? The efficiency of the motor to produce power via burning gasoline is what determines the mpg when all other factors are static.
For real world examples...let's use a car that has cruise control. You're traveling on the interstate, trying to go up an incline, with the car set at 75mph. If you're generating 10 extra horsepower from better fuel, the car will more easily climb that hill, and thus increase your fuel mileage.
Of course, all of the above is just speculation and there are other factors to consider. Like the fact that better octane fuel does not equate to more power like so many people believe.
So I was fiddling with "adversary" earlier and had the seat off. The is a sticker on the finder that say to use the low end octane. Also what oil to use and so one.

The truth is that 87 octane, or whatever the minimum is in your area, is going to be much fresher than the premium or mid-grade. The reason for this is because it's what the majority of people put in their vehicles.
Wanna fight about it?
Out back behind the sheds?
Put some kero in it, a spoon full of avgas per tank, whatever... the GS500 doesn't really care - BUT - don't put in ethanol fuel. If regular makes you all warm and fuzzy, use it. If the next up gives you a bone, use that. If top of the line sizzles your schnitzel then hook in, just use whatever you want that does not have ethanol in it.

Mister, here in the states finding ethanol free fuel is like finding a needle in a stack of needles.
In fl, its ~15% ethanol. Its politics.
There are FEW filling stations that offer ethanol free gas. And of those few, a lot of them are simply lying to attract the marine crowd and the occasional cyclist.
The best we can do is use sta-bil or the like for long term storage and buy ethanol resistant rubbers.
I think all the stations I've seen around here have ethanol at 10 to 15% concentrations. My owners manual says never, under any circumstances to use fuel with more than 5% methanol (wood alcohol), but ethanol is ok up to a 10% solution.

I said most because I'm sure there are some somewhere that have pure gas. However, I live in Atlanta, and here, ethanol free gas is a thing of the past. Sure, I could probably find one somewhere out in the boonies but I'm not putting hundreds of miles on my bike just to get ethanol free gas. :P
Having worked at a gas station while i was going to college the first time (1st time law enforcement, 2nd Millwright) usually the tanks that they put fuel in are different sizes, they don't just have a 5,000 gallon tank for each type of fuel: reg, prem, plus and diesel. (at least most don't) it will vary by the store some what because at least in new stores they will look at the area and see what the demand will be. also prem 91 at least in Minnesota is the most likely to not have ethanol in it or the least percent in it. that's the only reason i use it.

We won't run out.
When a well starts to lose pressure (oil is emptying) it is rested. Miraculously it fills back up again. SOME kind of reaction is going on deep Deep DEEP down that creates oil. Oil is not the rotting bodies of dinosaurs and trees.
Besides, Australia has so many capped oil wells it is not funny. I know people who have been drilling for, finding and capping oil wells in this country and offshore within our waters, for decades. We have Loads of oil. Why use your own when you can use someone else's and keep yours in reserve just in case?

I'd be interested if you could provide some information about the ethanol levels in various grades of gassoline. I always assumed ethanol levels would be highest in 91, since ethanol is an octane enhancer... But I don't really have any solid information to back that up.
I'm pretty skeptical that 91 is a better mix than 87... The regular, plus, premium thing seems pretty marketing oriented, and I don't see that the fuel companies have reason to use better fuel in 91, especially when there are a lot of ways to boost octane that don't actually improve the quality of the fuel (e.g. adding more ethanol.)
Now, to be fair, It used to be that 91 often had a better detergent package, but these days the gas stations are marketing the detergent in all their grades of fuel.

Octane is simply the pre-ignition and detonation resistance of the fuel. It doesn't speak at all to the quality of the fuel it's self. Without specific information relating to the quality of a particular fuel, I see no reason to expect that high octane fuel will perform better in an engine not tuned for it (E.g. our GS500)
Now, in the race world, there are plenty of fuels that are marketed based on their quality; often they won't overtly print the octane rating of the fuel on the can (though they will print it in their spec sheets.)
See http://www.vpracingfuels.com/motoroadracing.html for an example of fuel sold based on it's quality rather than it's octane.
Of course, what you say is absolutely true for modern high performance engines with knock sensors. A lot of time, the engine is tuned for high octane fuel, and then has a sensor listening for signs of pre-ignition that will de-tune the vehicle for lower octane gas (My BMW is that way.)
On the pump it self there was a sticker that has ethonal %, on non-oxy (ususally prem or 91 in mn) gas doesnt have a sicker that says that has ethenal in it where the ones that do will have a sticker somewhere. this is how the station worked that i worked at.
I usually run my GS on 116 octane. It adds like 50hp. I also use diamond plated oil filters and oil extracted from a rare 234 billion year old meteorite. So on a street tune I usually make around 1200hp on the dyno. (thats with the nitrous) :thumb:

Hahaha, well, how much can you compress diesel? I imagine its through the roof. I hope there's no ethanol in it, I have heard very bad things involving gasoline and diesel injection pumps... You see, the diesel is the lubrication for the pump, and the pump eviscerates itself when the non-lubing devil fuel we call regular gets in...

background with my bike, i commute and i have only owned this bike about a week and i have filled up twice at a rate of 2.1 gals per 100 miles each fill up, thats with 87 octane.
I will run this tank down and start using 91, i will report back after a couple hundred miles...

If you are in the USA or Canada, our pumps' octanes are listed in anti-knock index (usually written on the pump as (R+M/2) method) which is about 4 points lower than the research octane number (RON) that the rest of the world uses. So 91 RON would be equivalent to 87 octane in the USA and Canada.

Only problem with gas now days, is that the ethanol thats in it... Good lord. We pay almost $4.00 a gallon yet its alright to them to put 15%+ ethanol in our gas... And the ethanol destroys engines over time.
Not to start anything. but did you know almost 80% of our gas that we use in the states actually comes from THE STATES. the 20% is imported.. so what does that tell you? That the "war in the middle east" is a bunch of BS on gas prices.. And it's just giving them a reason to raise the prices. Just my 2 cents
This x100. The reason my bike was so screwed up when I bought it was because of ethanol. After cleaning out virtually everything (that stuff gets
everywhere) my bike runs like it's new. I still haven't installed a fuel filter and whereas most people I've talked to think the fuel here is fairly clean compared to where my bike originally came from I have my doubts. Gas companies would sell us water if they could convince us it was gas.
