Fuel Grade (regular, mid-range or premium)

[FZ6 Naked!]

Premium ONLY! (well, when I'm somewhere that it's available)

My wife had a Saturn SL2 and if you didn't use premium or mid, the car ran like hell. Not a huge thing, but if that little bit made that big of a change on the car, I don't ever even want to chance it with the bike!

IIRC those models of Saturn had issues with the temperature sensors. Something about them breaking and causing the computer to get improper coolant temp readings. Caused the cars to run poorly on low octane fuel.

i've experimented with higher octanes but i didnt really notice a difference so i use the regular.

I've used 93 octane for the past 4 years and just switched to 87 on this past tank. Surprisingly the bike runs almost identical and I'm expecting a bit more fuel economy!

Shouldn't be that surprised... says right in the manual to run 87.

Well after the first tank of 87 octane I got right at 50 mpg during normal commuting! I can't be sure it's all the fuel and not the warmer weather but I used to get 45-47 mpg on 93 octane.

Premium, despite the costs seems to get me better mileage.

Up untill last week i have bin using Shell V-power or BP Ultimate.
But last week i tuned the bike with regular 95 fuel. It was recommended to tune the bike for the lower octane fuel when installing a PC. so it will run wel on those fuels when you are on holiday.

But he said 95 here is more like 90.
V-Power and Ultimate are supposed to be around 97.

I'm not familiar enough with the FZ6 yet.

Does it have a "knock sensor" if it does, it should be able to adjust the timing to benifit from the higher octane.
If not then what is recomended would be best..
I have always run premium in all of my motorcycles, I consider it cheap insurance against knock and pre-detoniation..

I don't believe it does. However, even if it did most factory PCM programming is VERY conservative when it comes to advancing the timing even with a knock sensor and even of you were running race gas it would only adjust so much. You would need to reprogram the PCM to take advantage of that.

Hope this isn't a re-post. It is my favorite dead horse-beating pic.

 

[mikw73]

Oh, and while I'm posting photos of beating dead horses, I may as well take a swing: I think my '06 runs at least as well on the least expensive (US) 87 octane. My car REQUIRES 93, per the owner's manual, and if I put 87 or 89 in it it sounds TERRIBLE. The bike seems fine on the cheap stuff. Better even, I think. Maybe an airplane mechanic could put it to rest. Those things run stupid-high-octane gas. 103?

Horse = dead. NOT! (I'm sure.)

 

[abyss1406]

not going to lie, never felt the need to put cheap stuff in the ol scooter. I feel that premium from chevron feels better, and lasts longer too.

 

[Acumen]

I was always raised under the premise anything over 10.5:1 compression ratio should run higher octane ratings. Considering I just went from a car to this guy, I have no problem spending the extra mula for the highest octane rating; it's still so much bloody cheaper than my car!

 

[Downs]

There's a lot more to it than simply compression ratio.

Getting 52mpg with Regular, and the bike performs exactly as I want it to.

No reason to spend more money on something that you don't need to.

87 octane .... Enough said

I get much worse with 91 and more vibrations; plus Yamaha does recommend 87 for a reason. i would assume they do the research.

 

[TheRabbi]

I always try to get the "top tier" gas station (Chevron, Shell, BP, etc.) and if I can't then I usually use Premium at the other places.

No, Yamaha specify the MINIMUM. (87PON/91RON or higher)

Read it, it's there in the manual.....
