Hey, i don't know what octane the previous owner put in the bike. Should i just put the lowest grade in and it should be fine? What will happen if the it's a different grade than what i put in?

Its a 2009 kawasaki ninja 250r

Need a response fast as i will be running out of gas soon lol

You will simply get an octane level between the two.

No harm done, unless your bike requires higher octane than your putting in it.
 
How do you think pumps get 89 octane? (By mixing 87 and 91 for the ignorant) :cool: Just use the lowest octane recommended by the manufacturer (I think it's 87 for yours).
 
i talked to the previous owner and they don't know since they never filled it up, they bought a full tank from the dealership. I called the dealership and the guy said the highest octane. He said put 91.

There is no need or benefit at all for putting in a higher octane then needed unless you just like to throw money away.

Dont listen to him. Put in 87
 
Don't listen to the dealer. Listen to the owner's manual. The info in it comes from the engineers who designed the damn thing
 
My dad owns a gas station and between the ages of 7 and 12, I worked as (one of) the pump person every summer. I love the smell of 97+ octane but cant stand the **** if under 91. I buy Petro-Canada's Ultra 94, just so I don't poison myself or my passenger with stinking 87 octane at every red light chill. But then the company I work for always pays for gas :cool:
 
There's a reason I don't hang around the "general motorcycle discussion" section :rolleyes:
 
I find that 87 octane works fine, gives the same mileage as 94 for my bike.

87 makes the engine run rougher
91 shell makes the engine run cooler ( no ethanol)
94 makes engine run hot but idles very sweet and faster pickup

I have a pair of obnoxious straight through pipes so I could tell the difference. I always get about 20 KMS per litre on average. So I save my money and put regular with the occasional 94 fill up.

87 generally works fine in everything. I had a BMW rental that called for 91 and after complaining about the cost of gas to the rental company, they admitted they never use anything above 87 in it. Also, my SAAB calls for 91 and I just use 87 and don't even notice a decrease in power. My bike calls for 87 but does seem to perform better on 91 but that could have something to do with ethanol.

It's not about loss of power.. It's about knocking. Of course, if you aren't experiencing knocking issues you're probably OK, especially if your SAAB is rockin' APC, which adjusts to the low octane value by boosting pressure.

As far as I can tell it's not but I've never really heard what knocking sounds like so I might not even know, lol. From my reading, however, my car does have APC.
