What kind of gas do you put in your F4I. Will it hurt if I put the lowest grade we have at our gas stations around here (87 or 88). In my owners manual is says 86 or higher. Is it worth it to put in the expensive stuff. I don't think it is but I just wanted the opinion of everybody else. Are there any benefits if you put the higher grade in or is it just a waste of money???. Thanks for all your input.

youre buying 4 gallons at MAX 30 cents difference, thats $1.20, dont be cheap

I use the cheap stuff. There are a lot of posts about this subject on this forum and a few of them even explain what octane actually is. I found it very informative and with the information that I collected I choose to put in the lower grade gasoline. Just do a search for octane or gas and I'm sure you'll find a lot of stuff here, there are a lot of knowledgeable people.

well...if you understand the whole octane and combustion and engine thing...then you'll use the lowest octane possible without predetonation.

If you have your manual it says inside.

When I bought my gixxa 750 new the sticker on the tank said 93 octane I believe all of them are the same.

JZHALES I'm not cheap bro, I just wondered if it makes a difference. Why would I spend more money in putting the higher grade in the bike if it doesnt do anything.

yea in my manual it says 86 or higher but I just wanted to know if the higher octane helps the bike run any smoother or if you notice a difference.

true, but my point was the difference is like a dollar, but ive ran 87 before too, i dont really care to be honest i just run 93 but thats probably not necessary

I use 93, but if you factor in one dollar to a dollar twenty more every time you fill up, times how many tanks you burn in a season, it adds up to be quite a bit.

Oh boy...the gas question. This is a can of worms. I use the highest octane available, but there is more than enough evidence to prove that I am wasting my money. The manual says to put in "86 or higher". Use the lowest grade you feel comfortable with, and if you hear "knocking"...upgrade.

voodoo...you should save your bling and run 87 and then use the extra to buy wifey some lingerie! muahahhahah

I find my bike knocks with 87 so I just go ahead and run 93.

I get the best gas milage with 91.

[sm=goodidea.gif] Tahoe, do you run anything different on the track, or just the 87?

FWIW, I run 87 and don't run anything different at the track. It wouldn't make sense to do such. If the bike isn't tuned for higher octane fuel, it won't make a bit of difference since the bike doesn't know street vs track vs me & Tahoe's wife's favorite hotel parking lot.
