which kind of gas?

Oh yeah , i forgot to mention, i have never run anything more than 89 in my bike other than to put them up for the winter and i am sure even that does not to a whole lot for it, i just want to have a higher grade gas to add the sta-bil to.
 
87 / no knocking / 14K+ on the original plugs / :rtfm:

I've run mixed gas in my FZ6 before (long story) and I've run 110 once in a bind at the track...didn't notice any difference in performance either time.
 
My 1200 Sporty is designed to run on 87 octane from the factory however, if the temperature gets above about 85 ambient I wouldn't go near 87 octane as the engine temperature rises significantly and the bike generally runs like crap.

More so than usual? (Sorry, obligatory Harley joke)

The major difference on the Sporty is that it's air cooled. On hot days, the engine is going to run much hotter, and as you said, octane can become an issue. The Fizzer will just kick on its electric fan and stay cool.
 
Main thing to remeber is to run a brand name of fuel. no "bob's petrol mart" watered down camel pee. The only reason i run higher octane is because of the added detergents. and it makes me feel better ;)
 
HavBlue and Fred are right on. There's no benefit from using---read PAYING for---(r+m)/2 rated higher than 86-87 in your stock FZ6. One of the biggest sales ripoff is how oil companies are marketing these different grades of gas. They don't really go out of their way to deceive motorists but nor do they explain it all. Very few modern motors nowadays require---or can benefit from----"supreme" or the other non regular marketed gasolines. Did you know that different brands of gas often come from the same refinery? Companies then will pour in additives to increase octane or help the process run cleaner. But, you'd never guess it by the marketing. How many motorists fill up--and pay for--with "premium" grades of gasoline and don't realize that what they're paying for produces no benefit?

I beg to differ. I have owned several cars that needed super, otherwise the ignition system will retard the timing resulting in less power. I have also noticed that I get poorer mileage in those cars when using a lower octane fuel.

In my VW Passat Turbo I run 93, the Mercedes E500, super, '02 Porsche Carrera, super, the GMC Sierra, regular. The higher the compression engine the greater the need for a higher octane to slow the burn of the fuel in the compression stroke.

Now I agree a Civic or Camry will not benefit from using 93 instead of 87, it doesn't have the compression to require it. That said on a super hot day super or mid-grade can prevent pinging, ie: Dallas stop and go traffic in August when it is 110 degrees, or pulling a load.

I also agree with what MadMan said, the brand name gas has more/better clearners in them than Billy Bob's Quickie Mart. Yes pretty much all gasoline comes from a few refineries, Shell puts on X additives, Chevron Y, Exxon Z, Billy Bob's the government minimum.

As far as our beloved FZ6, I run Super, its only .20 cents more per gallon. Remember that modern motorcycles are very lean from the mfg to meet emissions, hence the Power Commander. Most fuel to air tests have our mid-range at 13:1 or 14:1, a bit lean, more prone to pinging on a hot day under load.

Bottomline, run whatever you wish, just don't allow your motor to ping.

agreed, but the compression thing is kinda off..... think about diesel's, high compression, lean conditions, and lower octane fuel. but strong enough to contain detonation.

i wish premium was only .20 cents more! its like .40 more here and my g/f's acura takes only premium!
 
wait a minute.....Top what does the wifey do? did you win the lotto? rob banks? big inheretance? thats a lot of cars for a measley first sergeants paycheck! or is that why us lower enlisted got shafted so bad ;) ?

Wifey is a geographer/geologist for a small oil and gas firm. Remember I'm Guard not AD, I've been in semiconductor capital equipment for about 14 years. The company I work for makes the equipment that Intel, AMD, Samsung, etc use to make chips. I've also been foretunate in the stock market over the last 30 years. I started investing when I was 13. I also like to buy cars that are 2 to 3 years old and still have warrenty on them. We got the E500 for $29,000 with 27K miles, and 13 months of Mercedes warrenty left on it. For the truck I bought an '07 when GM was blowing them out this Fall, kind of like my FZ.
 
91 Octane

I run a minimum of 91 Octane. Aparently the FZ6 engine was designed to be run anywhere on the globe, hense the reason it can take regular, but my salesguy was telling me that running 91 will keep the valves cleaner.
 
Ok something is not right...maybe the fuel sensor?
The last gas bar started blinking at 123 miles. I drove 5 miles on the blinking bar and then filled her up with 89 Octane. Only put in 3.78 Gallons! I still had over 1.4 gallons left!?!?!?

Whats going on?!
 
That does sound a bit off.

The simple solution is to adjust the fuel level sender by bending the metal arm that the float is on. In your case, bend it up slightly. Small changes are important, don't make major adjustments.

You may be able to remove the filler cap and reach into the tank to do this. If not, you'll have to drain the tank and remove the whole assembly from underneath.

Or just learn how your particular bike behaves and live with it. (The easy solution.)
Your fuel light is coming on early and your gauge reads lower than average, but you're not going to have less range than any other bike.

I just put in a tank of 89. I talked to the bike shop today and they said they only heard of one issue like that and then that guy never contacted them again - so they dont know what happened.

I'm thinking I'll just keep running tanks of gas and see if things change. Otherwise I'll have the shop look at it durring the 600 mile maintenance.

DANG! I want to get to the 600 mile mark! My bike is just begging to break free from its current restrictions!

Actually I have often wanted to run an oil temp gauge on the FZ6 because the Sporty oil runs that cool and I would like to see if the FZ6 does as well. The issue with air cooled falls back on combustion chamber temperature and not necessarily overall engine temperature.

The Sporty is 10:1 vs. the FZ6 at 12:1. Generally when the temps are in the 90 degree range the Sporty oil temp will run 190-200 degrees. On a 70 degree day the oil will rarely get over 150-160 degrees. It will run on 87 octane but regardless of the ambient temperature, it ain't gonna like it.

The last bar blinking on mine has been at 4.1 gallons since the bike was new and has never changed. I'm trying to figure out how you're running 33.2mpg while riding in a restrictive state. I could run 85mph down the interstate for 100 miles and not drop below 42. I don't baby the bike and I generally run around 46mpg although I know it will hit 54mpg if I am riding with the guy who owns the property next door but that is at the pace of a Gold Wing.

you missed something. the diesel combustion chamber is designed for high compression (which really doesnt matter) but there is absolutely no fuel in the combustion chamber when the AIR is compressed. the FUEL is injected into the super hot compressed air and then you have ignition. so there is no issue as with a gas motor where there is already an air and fuel mixture. in a diesel engine there is no fuel to burn on the compression stroke.

run the lowest unless it detonates.
