I fill up 2 maybe 3 times a week. 3 gallons each time. 60 cents extra each fill up. 1.8x52=93.6... I'll stick with 87 and still get the same performance as your 93, thanks.

 

And that's fine Whatever works. It's going to be one of those eternal six of one, half dozen of another questions.

 

teko, the grocery store example was horrible lol. Not to be rude. The numbers you gave me in apparent what you'd buy, maybe 15oz for 2.98 lol.

 

Well, my experience states that the 87 runs nearly equal to the 93 in my F4i. I normally get 130ish miles per tank. (that's taking into account the error from my non-stock gearing.) I've tried this on multiple occasions and have noticed no discernable difference between the two fuels beyond price. For all of those nit-pickers out there, I use Chevron gas at all times (I have an account with them). Personally, I say use what you can afford and makes you happy.

 

Ok everyone breath....now this is an eternal arguement.

Some believe higher octane=better gas/better performance. I say it is placibo effect.

I fill up with 87,perfer no ethanol, every 160 miles or so. Bike runs great and have tried 93 with no changes in performance.

All fuel is the same, the difference between brands is additives and better storage practices/ higher turnover in stock.

Gasoline at the pump is stabil for at least one year after manufacturing

Rennen I promise that you did not lose 40mpg simple from octane switch, octane does not have the ability to alter the amount of energy produced in burning the fuel. It inhibits pre-ignition.

So unless your bikes engine is "dieseling" uncontrollably I say you were getting on the trottle harder to "check" performance.

 

w/e. everyone has their own opinion, and it's not going to change. people should do what they want to make themselves happy.

 

Finally someone who knows higher octane does not = quality/ performance!

some people are so ignorant

 

You catch more flies with honey than vinegar.

 

I could go back with my camera and take a pic if you like. That's exactly what the price was. This was miracle whip and not plain mayonnaise. Sad part is I bet a lot of people bought the bigger size without even comparing the price.

 

I have a1997 CBR F3. I always run premium. is this bad? better? or the same?

I wanna see proof cuz I dont really believe that premium can make the bike worse...
