Thanks guys. I dont care if the manual calls for 87, cause I'm still not putting that low grade in there. I only have a 4.5 gal tank, so 12-13 to fill er up on premie doesnt bother me. I'll just forget about the octane booster, cause it seems like a waste of a couple bux. I could be spending those hard earned dollars else where. (Im not suggesting it to be spent on some bud-light) wink-wink.

 

You don't want to spend extra money on octane boost because you think it is a waste of money, but you will spend the extra money for the higher octane you don't need? It is the same principle, either way you look at it your are wasting money....

First off there is no such thing as "low grade" fuel. The quality has nothing to do with the amount of octane additive it is all processed the same way.

 

The octane "does" matter guys wtf. The high octane is cleaner burning and does help performance. If it doesnt matter than why doesnt NASCAR save money by using friggin 87 octane instead of using 100 octane racing fuel.

 

Because they run higher compression than your bike. Octane rating is basically a number that tells you the fuels resistance to detonation. So if you have low compression pistons then 105 octane would cause you to LOSE power because all the fuel wouldn't burn. All this has been proven for many years and if you want to be enlightened go read an article on the subject before throwing out completely wrong info.

 

i always thought the higher octane fuel burned better, and not only that, was cleaner than the cheaper grade. i'm sure i'll be wrong with this, but i always thought if i used 87 octane i'll be in need for a carb cleaning sooner than if i used the higher octane. my 900rr is carb'd, so i can get away with using lower octane in it as opposed to my nissan 300zx, which is FI, and will run like crap with anything less than 92-93 octane. dunno the compression in the 900rr yet, but the Z is 10:5:1 and i dunno if that's considered "high compression" or not, but low octane runs like crap in it....

i've only filled up the tank in my 900rr once since i've had it, and a friend told me to go ahead and put 93 in it. i was gonna go the 87 route since it was carburated. my line of thinking is so off i'm sure lol

 

Here's some facts.

'20/20' Takes on Summertime Myths
http://abcnews.go.com/2020/Health/st...=939056&page=2

The Price Is Premium, But 'Gas Is Gas'

When you head out on vacation this summer, you'll probably spend big bucks filling your car's gas tank, while griping about the price. But a lot of you who are complaining could be spending less for your gas.

You have a choice of gas at the pump. The price of 93 octane premium is more than regular 87 octane — about 20 cents more per gallon at many stations. Because premium costs more, a lot of people think it's better for their cars.

People told us premium gasoline gives them better gas mileage, more power and cleaner engines.

Regular gas, one woman told "20/20," "leaves a lot of gunk in your engine … That's what my daddy taught me."

But her daddy — and many of you who buy premium — are wasting your money.

NASCAR driver Joe Nemechek knows this. "Believe me, I've pumped gas in from about every gas station there's been in my personal cars. Whether it's around town or on vacation or wherever, you put the regular in there it keeps on running," he said. The NASCAR drivers, mechanics, and car makers will tell you that for 90 percent of the cars sold today, high octane is no better than regular gas. It won't give you better mileage, more power or a cleaner engine. NASCAR crew member Lisa Smokstad told us what every expert told us.

"It is a myth that cars run better on premium gas," she said.

Some cars do need higher octane — older cars that knock, and cars with high-compression, high-revving engines like Ferraris, Bentleys, Jaguars, Acuras, Mercedes and Corvettes.

But 90 percent of new cars don't need it — check your owner's manual.

The car manufacturers and every car expert we consulted told us that for most cars, high octane is a waste of money. Even the gas companies that sell the high-octane fuel — and make more money off of it — admit most people don't need it. But they don't go out of their way to tell you that.

Once you've figured out which octane to buy, does the brand matter? Are the well-known national brands better than the no-name brands, which are usually cheaper?

People we spoke to gave similar reasons for buying name-brand gasoline that they gave for buying high-octane gas. They believed the national brands were higher quality, and better for their cars.

But they may not know that all the gas, brand name and generic, comes from the same refineries. Brand names do use different additives, but it doesn't make them better for your car.


In 1996, the Federal Trade Commission forced Amoco, which denied any wrongdoing, to stop claiming in its ads that it was better than other brands without scientific evidence to back it up.

"It's a myth that brand-name gas is better than a no-name gas," said mechanic Dave Bowman, co-host of "Two Guys Garage" on cable TV's Speed channel.

"It doesn't make any difference whether you're buying a branded product or a no-name product," he said.

"The only difference is price."

The NASCAR drivers agree about that, too. "It's a myth, you don't need the high-octane gasoline, you don't need the, the name-brand stuff," said driver Jimmie Johnson.

Some of the fans have figured that out.

One man summed it up nicely for us. "The manufacturers and the gasoline dealers, they all want you to buy that expensive stuff. It all runs on the same stuff. Gas is gas."

not to totally offend you or anything...but that is pretty ignorant dude...facts show one thing and the science is all there...but you decide to look the other way...

 

I'm not trying to be, or sound ignorant. My buddy has a newer ninja, and he filled her up with low test gas a while back. For a while his bike ran and sounded like absolute crap. After he had enough, we syphoned out the old gas and filled it up with premium and let it run for a while to get that gas flowing through the lines. He took it on a test ride and I went with him. The gas made a difference in his bike. It idled smooth and ran a lot better. Thats why I'm saying that I will use premium. Sorry guys, I'm not trying to be ignorant I was just asking for other peoples opinions.

ok dude, i sounded like a total dick when i said the ignorant thing. i so apologize...but good you didn't take it the wrong way.
check this out...for older motors that have carbon build up in them, they tend to run hotter than new motors that are all nice and smooth like my wife's legs....but that's not my point here.

so with these bikes that run hotter because of the build up, you'll need to run higher octane because regular would cause it to predetonate, but if you gots a brand spanking new motor and haven't done anything to it nor mess with the a/f, timing, etc...then you should just run the minimum required so it doesn't ping.

my bike has 38K on it, but i still run regular cause i haven't heard it ping at all...i'm sure there are some deposits on it though...also...when i'm riding that thing...with the rattling cctl and the exhaust, i can't hear ****e anyway!
