Bad Gas?

hello fellow riders,
I have already googled my concern but I didn't come across any threads/info same as my situation. I have been riding for the last few days, bike performed as it should be.
Yesterday I filled up at petro canada, 87 octane in Ancaster drove to Sauga, today when i started up my bike, it idled for few seconds then stalled, i started up again, i saw smoke from exhaust and nasty smell too. Plugs checked out okay so did oil level. I dumped the gas and held the throttle partially started up the bike again and kept it at 4k rpm until all the fuel ran out. (if i wouldn't hold the throttle the bike would stall).
Put fresh fuel bike started up FINE, drove same as before.
I just want to confirm it was the bad gas. I just want to get your opinions and opinions of mechanically inclined riders so if there is any other stuff i should check out, better safe than sorry i guess. Yeah, it may be a no brainer for you, but I'd rather be a noob, hear somebody else perspective in order to enhance my knowledge.
Thanks
ps. Bike's 2010 gsxr 600 16k kms, pc v full system exhaust. maintenance up to date.
 
edit

my apologies

apparently im retarded

87 octane


i suggest you take a little lookie-loo in your owners manual for the proper octane fuel to put into your bike
Take heed of your own advice before bestowing "wisdom" onto others.

OP, what was the colour of the smoke?

Hold up I'm putting in v power for nothing? Let me check the manual I swear I seen 91 oct.

If anything your putting in vpower to get away from the crappy ethanol in the other brands.
Most bikes don't need anything more then 87 but they will all benefit from non ethanol fuel.
 
8 posts and I am cleaning up people calling each other retards?
You might think someone is being dumb but please remember, if you have nothing nice to say, then say nothing at all.


I never put less that 91 in any of my bikes. I find they are generally just happier. But yes its possible to get bad gas and my suggestion would be to use another gas station and avoid that one. The gas is prob sitting in their tanks too long. Messed up my F150 once due to bad gas.
 
i have the same bike minus some of the upgrades and the manual says 91.... i've only put in 91 and i have no problem. 87 would be better on the wallet but dont think its better for the bike.

Like someone else mentioned above, most likely your bikes feel happier because 91 gas at most gas stations has no ethanol in it.
 
If there was a fresh delivery at that station as you were there apparently that can stir up gunk in the holding tanks.

Run off and rain can also introduce water into the tank. Had that issue once with the station in Campbelleville.

If water is getting into a gasoline holding tank, that's more of an environmental issue than anything else.
 
I hope everyone here realizes that octane rating has nothing to do with the quality of the gasoline, but it's resistance to burning. Higher octane means it is slightly harder and takes longer to burn, making it manditory in engines that are running a high turbo boost (like my Mazdaspeed 3) and high compression (Like in the Civic SI). These motors already have the timing tuned to be more advanced than 87 octane rated motors making the burn period longer. If you use 91 where 87 is recommended you are not only burning up cash from your wallet but you are creating surplus amounts of unburnt fuel going through the exhaust side of your engine leading to clogging of the catalytic converter(s) (if you still have it/them) and also excess carbon build-up. Using 87 where 91 is recommended can lead to knocking and pre-ignition, especially in those turbo motors where boost compounds the engine's natural compression.

I see so many people with stock base econo box cars like Yaris and Civic filling up with Ultra 94 and it just makes me laugh. Not only are they wasting money but they are using a fuel their engine was not designed for (which over time can be very bad for it) and are completely oblivious. Any difference you may "feel" with using 91 where 87 is recommended is all in their head but these people like to argue up and down they SWEAR they can feel/hear/see a difference.

Keep in mind Europe/Asia uses a different octane rating system than us here in North America. 91 RON (Europe/Asia) which is in most owner's manual including my own '09 FZ6R is equal to 87 AKI (here).

Taken from Wiki:


"Difference between RON and AKI

Because of the 8 to 10 point difference noted above, the octane rating shown in Canada and the United States is 4 to 5 points lower than the rating shown elsewhere in the world for the same fuel. See the table in the following section for a comparison."

Or, in more simple terms, your engine makes the best power on the lowest octane gas that it will burn, without engine knock. Anything more is a waste.

Yea but that dosnt sound as smartish ;).
 
My bike says right on the tank "minimum 95 octane" so I only use Shell V power due to the non ethanol content as posted only on Shell 91, then I use octane boost. Ultra 94 with ethanol is not a true 94 octane. Gone are the days of Sunoco Gold 94 that had no ethanol.

What does the manual specify for the octane rating; RON or ((RON+MON)/2)? You might be wasting your money. See "Difference Between RON and AKI": http://en.wikipedia.org/wiki/Octane_rating
