who sais you cant run high test fuel?

[Susuki_Jah]

ok for some reason I could have sworn someone had told me sometime or another not to run higher octane fuel in the GS higher than 87. I have no idea why this stuck in my head. so I am at the local bike shop talking to a racer who was ordering me all the parts for my gs rebuild and I asked him about running some fuel cleaner through the bike, and he goes why dont you just run high test gas because all the fuel cleaner does is boost the octane eh we went into more depth on what it actually does for you but he was like just run the hightest in your bike. and then i was like DUH why did I ever think I coudlnt he was like yea why did you haha and we got a good laugh. I could have sworn it was some kind of statement made on here somtime. am I right or am I crazy lol

Well, the GS really doesn't have the compression or timing to take advantage of high test, so I have seen people on many bike boards recomend not running anything other than 87 in it for economic reasons.  I personally would use a cleaner designed for carbed engines and call it good.

There is no good reason to run high octane in the GS.  None at all.  It doesn't do anything to help it go faster.  It doesn't burn cleaner.  Octane is like a flame retardant.  More flame + more air + more fuel = more power.  I switched from high octane to the cheap stuff and my bike ran 10 times better.

I dont think that anyone here would have said to not use high octane. I have seen many posts about it and most just say you can but it doesnt make things any better 

[Susuki_Jah]

well I wasnt exactly wanting to use it to go faster. I want to clean the fuel system and that higher octane works to help clean it because thats all that fuel system cleaner does anyways boost your octane. 

I dont know where everyone gets the idea that anyone who wants to use a higher octane fuel would think it magicaly makes you go faster. there was a logical reason behind it. I have been learning a lot of nice tricks of the trade from the guys who race bikes at kens cycle here in VA they have a gs500 track bike too and love it.

well anyways Im pretty sure it was brought up in a debate before because not everything on the board is practical, logical or even true. I would say there are a select few on this board who I would beleive 100% of the time. and well they know who they are.

thanks for the post.

I'm certainly no expert on gas but higher octane only retards the combustibility  of the gas so it won't detonate under the ideal conditions. I've heard people talk about running high octane racing gas in their vehicle like it's going to oxgenate the fuel as nitrous will. High test gas is supposed to be better at keeping an engine clean so I guess theoretically it could work as a fuel system cleaner. This would probably be due to additives rather than the actual octane level. As for myself, I'm a tightwad. The cheapest gas that burns is what goes in my tank.

[poolshark]

Not that it matters (apparently), but I thought I'd weigh in:

Whether you believe it or not, that "burning cleaner" myth is just that: I have personally torn apart engines run on high octane, and, unless higher octane fuel is necessary, they rarely look better, often worse. Really, the only purpose of a higher octane fuel is to compensate for pinging, often caused by high compression or advanced timing. The GS has relatively low compression and timing shouldn't be advanced that far, so high octane fuel is really a waste. Extremely high octane (ie. race gas) can even leave extra deposits in your engine.

In conclusion, run the cheapest gas that doesn't ping, and you're golden.

well I still feel as if no one has honestly got what I was saying. I am not looking to run 93 octane fuel in my motorcycle on a daily basis, I am filling it up one time with the higher octane fuel to help flush out the system with the higher octane the fuel burns hotter and does the same exact thing a fuel cleaning additive does when you add it to a lower octane fuel. Instead of waisting my money on a tank of gas and a fuel additive I am filling up with a higher octane and saving myself a little bit. I am not saying that running a higher octane will keep your engine cleaner or it does anything for the motorcycle . but if everyone wants to argue even though Im agreeing with you then be my geust lol.

[NiceGuysFinishLast]

You're not listening to everyone else. You said you're using the higher octane gas to flush your system. Not really. It mixes with the 87 and gives you (87+h)/2 where h is the octane of the gas you're using.

It will NOT do the same thing that adding a fuel additive does to lower octane fuel. Seafoam, for example, is a great fuel additive for carbed or FI engines. It is NOT simply an octane booster, it actually cleans carbon deposits from the engine. You can not argue that 93+ octane gas is the equivalent of a can of Seafoam. It just doesn't make sense. It'll get you laughed at.

I am not saying that running a higher octane will keep your engine cleaner or it does anything for the motorcycle .

Oh no? Then what are you saying?

Oh, I think you're saying this:

well I wasnt exactly wanting to use it to go faster. I want to clean the fuel system and that higher octane works to help clean it because thats all that fuel system cleaner does anyways boost your octane. 

Contradictory, no?

[Susuki_Jah]

well Im going to stick with the opinion of the guys who own and built there own race bikes and who own the shop here in Richmond and are licensed racers and mechanics for these motorcycles. and on top of it run gs500's .  but all of these arguments I was not arguing. I am not running 93 octane in my motorcycle on a regular basis. I never said I was going to nor do I wish to. and I am no oblivious to why you run or why you dont run higher or lower octanes the principles are the same in cars and trucks.

I mean damn some people can just run this crap into the ground.

I got all of your opinions now close the thread.

+1

[Mandres]

because all the fuel cleaner does is boost the octane eh

You either mis-interpreted what he said to you or he doesn't know what he's talking about.  Some brands of premium gas add detergents, solvents or stabilizing additives to the mixture to, for the most part, justify the higher price.  These additives are not related to the octane level although they can influence it. 

Running a single tank of premium through the engine will not have any measurable benefit.  It certainly won't "flush it out".  The additives make up such a small percentage by volume that even over time it's all but impossible to tell any difference.  It's debatable whether a can of Seafoam, for example, does any good either. 

The best way to keep the engine and fuel system clean is to use fresh, high quality gas with the correct octane level and to keep the air/fuel mixture in proper tune.  If you're that worried about carbon deposits you can just clean and rebuild the top end every 50k miles.

[Susuki_Jah]

well I think we were more or less talking about a more specific type of cleaner that they had there and in all honestly thats probly what we were soley having conversation  about at the shop. I have used things like seafoam and other products in vehicles before never really noticed any benifit from them either even when I did pull apart the engines I didnt see any difference in the ones I used it with and didnt use it with. 

I think to save my self the hassle of using any of the crap Ill just rebuild the whol damn bike.

for the record I agree that the high octane fuel wont make my life any better. I think im still going to give it a go around though, never have run the bike with it yet.

Josh...you continue to prove your intelligence again and again...

Seriously JAH, you asked a simple question, had the answers within two posts, then proceded to ignore everything and tell us how much smarter your friends are.  I suggest you ask them these questions, because every time you reply here (and over at Turbobricks too for that matter) you come off as a troll.

[nightrider]

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.

[CO_GS500]

If the objective is to have some cleaning affect on the fuel system, talk to a senior tech in your local bike shop about what cleaning additive he recommends.  I'd post what I use, but I don' like getting flamed for being a troll, hobbitt, mutant or whatever those who use forums as lame advertisements are called.

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:

"im so cool I must have gotten the first dis post in YES"

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..
