I've always used chevron super unleaded, but now I'm wondering if it even makes a difference at all.

Any insights into fuel?

87 octane, my scoot is a cheep my mama

Any DECENT 87 octane gas is fine.  I say decent because I've noticed (only in the past few years) that all gas is NOT alike.  It used to be that I would get gas at the cheapest place regardless of the "name".  Well, it seems that that doesn't work any more.  Now SOME cheap gas makes my car ping and my bike lose power.  With the car it's annoying hearing it, and I know the engine doesn't like it.  With the GS it's like the choke is on, it has trouble a the higher RPMs and no power.  So now, I ONLY buy gas from the "larger" companies.  I stay away from "Bobs gas" and the like.  With "name brand" gas, I never have any problems.

I have an 04 500F and the manual recommends 91, so that is what I give her.  I also have a manual for an 03 naked 500 and they recommend 87 as a minimum.

91 is what is recommended for Canada, US version just recommends an 87 octane. That's what I use. Have tried premium, but no difference from what I could tell.

...87 octane;  60-62 mpg.

i give my baby the new v power!!! from shell

with my bike i'm a lot less picky. 87 octane whatever.

with my car i'll only give her preem, and almost exclusivly BP Amoco gasoline.

Strictly Super from the big four. Chevron, Texaco, Shell, 76. I might waste a buck over the month not buying the cheap stuff.

Chevron, BP, 76, the occational Arco, Valero. All 87 octane. Never Shell, the additives score the jets; minute, little scratches impede fuel flow through the jets.

I prefer Chevron due to the cleaning qualities of the Techron (oxygenated) and the bike just plain runs better.

87.  If the bike doesn't ping with 87, anything more is a waste of money.  I have tried out a slew of local stations with my 87-sipping-non-knock-sensor-equipped car, and found the only discernable difference to be price, so I go to Arco or Chevron, whichever's closer.  Arco does have low-sulfer gas, so I can feel environmentally virtuous as well as like a cheapskate.

Cheep crap... 87... jetted to the gills, I dont believe it an even use more gas if you filled it direct in the motor...  :lol:  Rich mix = super slow burn... = no knock.
Cool.

the gs and i are still in the honeymoon period, so i feed it ultimate.  i'll probably end up using regular unleaded eventually, but for now, the money seems rediculous anyway.  after feeding my olds 15 gallons every 300mi, pumping in 3.5 into the gs every ~200 mi seems like a relief no matter which gas i choose.

oh yeah, unless i'm sputtering in the middle of nowhere, i use BP exclusively.  i used to get cashbacks from them for several years, and old habits die hard  

I'm in the honeymoon period, too, but I'll spend it on synth oil and wax.  

My bike says on the sticker right underneath the seat 91 octane minimum. Took me by surprise, but the bike sure does like the better gas more... at least that's what i've noticed. So i throw in premium.

I will say this... I would take 87 from Sunnoco before 92 from sheetz any day of the week.

back when I had the R6 (a bike which actually needs high octane fuel... 12.4:1 compression), the sheets gas made it sputter and jerk like a beyotch... as soon as I put Sunnoco back into it... butter.

I think with lower compression bikes like twins, the brand is more important than the octane rating.  I don't know where cheaper places like Sheetz go to get their gas, but they must be cutting a corner somewhere because their gas always made my bikes run like crap.  I always used Sunnoco 87 in my GS and never had a problem with power or rough running.  I think 'premium' is a misnomer.. its not better... its not cleaner... there is no additional energy in the gas or anything like that, it just detonates at a different pressure because it has a different ratio of branched-chain to n- alkanes.  Of course, the gas compaines love the fact that the public thinks it is actually better in some way... more profit for them when joe-shmoe fills up his camry with gas that's more expensive than it has to be.

:dunno:

I use Shell premium and always try to stick with it so I'm not mixing different brands of gas, cause they're all a little different.  And I don't think it can hurt using premium... it's like an extra $1/fill

It boggles my mind how many of my friends with low-compression engines use premium.  Just because it's 'better'.   :dunno:

i use 91 or better all the way... i notice a difference... 91 is much more peppy than 87  

I give my little devil 91
