MPG

[FuZzBoM]

hmm maybe the modifications make a big difference. i have pipercross filter, iridium plugs, ART straight thru can. also only run it on shell V-power
I guess all that could make it terrible on fuel lol

Try changing gear!  :rollin

Out of interest, has anyone bothered experimenting with different octane fuels? Aka do you find standard unleaded better than the premium unleaded?

My car (Mark 2 Golf) loves premium compared to standard but the bike seemed the other way around. Since then ive stuck to standard for the bike BUT ive now renewed the exhaust system and air filter...

I did wondered this myself. people say the fazer over fuels so is it just a waste of money? the general thinking with higher octane is a more pure burn. i again notice the difference on my car. i wouldn't say it had more power but does feel smoother. i also get better MPG on the car with higher octane but then on my car that is accepted as the norm. (3.2 litre vectra)

filled the car up today...sold out of regular so had to have UNLEADED PLUS.car seams smoother on way home,ill see what it does to the mpg and let you know ....never tryed it in the bike

trying desperately to remember why a higher petrol RON rating for a motorbike was a waste of time and the relationship to engine knock,,,,

One of our users commented that using higher octane fuel than your engine requires actually gives no benefit and may be a waste of money. This is because virtually NO engines require 98 RON over 95, and the market for ‘super’ fuels seems to be based on people’s misunderstanding of octane ratings and the placebo effect of filling up with ‘more powerful’ fuel – making motorists think their engine is running better in some way.
What do the fuel companies say then, to justify the “increased power” claims for the super grade fuels? Some companies say that while all fuels contain cleaning additives, ‘super’ fuels contain more or better detergents to keep the injectors cleaner than standard fuel. Others say the fuel is a few percent denser which gives slightly more power per litre. These benefits may be marginal though in comparison to the extra cost involved so it is worth ensuring that your engine will actually benefit before filling up.
Some engines actually do need higher octane fuel, such as race engines with very high compression and some turbocharged engines, such as the import version of the Nissan Skyline. Also, a few vehicles, such as the new BMW K1200R motorbike, can sense knock and adjust their engine tuning to take advantage of higher grade fuels. Another user commented that the 2004 BMW 330 also does this, according to the driver’s handbook it makes 231 BHP on 98 octane and 221 BHP on 95. This ability is apparently widespread amongst German performance cars using Bosch / Siemens electronic engine controls.

got a stubby end can and k&n air filter and get 60+ every time

but vary rarely go above 6k and usually cruise around 4k

poor student

but then,went cat and fiddle the other weekend and got 103 miles off a tenner,wern't hanging about lol

It all makes sense, but at the end of the day it boiled down to trial and error for me Was simply curious if others had found the same results and if it was because of any specific modifications. As I said before, the bike didnt really seem to like the higher octane fuel but it still got me where I needed to go

The car on the other hand (until it died) loved the higher octane fuel, it was smoother and felt slightly more powerful. Just for the sake of making sure it wasnt a placebo I had my friend fill up my car randomly with with either just as an experiment But having said that, even a different car of the same make, model and engine will perform differently... hence returning to my curiosity with the bike

[FuZzBoM]

I think some of it does depend on the engine setup. if it is a modern engine with a decent injection system and knock sensors and variable valve timing etc. higher octane fuel will give a benefit. if the engine has a better burn the ecu will pick this up and account for it. hence why i say my car does feel as though it benefits from it.

thinking about it i have a mate who had an imported EVO 5 and wondered why it really hesitated before the turbo kicked in. it turned out he was running on 95 ron. when he switched to V-power this 'fault' he had me trying to figure out went away and ran perfect from then on.

For me its mainly my mechanical sympathy and thinking i am doing the right thing for the engine  :lol

52mpg last check.  And that was after a three hour advanced riding lesson blasting through the country roads...

[110%]

I'm normally getting 55mpg from mine.

Theoretically the optimum MPG is achieved when the engine is running at it's peak torque in top gear. Apparently for an FZS600 peak torque is at 9,500rpm. I tested this out today to see what speed I would have to be travelling to achieve 9,500rpm in top gear. Put it this way - I'm glad I wasn't caught by the police whilst testing it out!!  :lol

[john 087]

average about 50 mpg plus around town, on a long drive can get 60 mpg

Drive a bike?  :eek

Ride  8)

[rjd1]

96 mile to a tank full, from light on to light on

[redman]

LOL at 96 miles to a tank you must redline it everywhere :eek im averaging 55 mpg with a K&n Air Filter will changing my end can to a Beowulf affect the mpg in anyway?? 

[Dead Eye]

I've put a K&N Air Filter on mine plus a Beowulf Warrior end can and havent noticed any appreciable decline in the MPG - i've just started using Fuelly to try and get a better idea of how much I actually spend on fuel etc.

[JZS 600]

Well, thrapped mine last weekend, high revs in country lanes and high speed (at least 3 figures) on motorways and got 58 MPG, 185 miles  ridden including 2 commutes equating to 14.29L of petrol, which I think ain't half bad!

Anyone tried Iridium plugs?

[peteski]

They do but octane rating has no relation to air-fuel ratio.

the general thinking with higher octane is a more pure burn

Really? I don't think it is.

All i said was the general thinking i didn't say it was correct or not  :rolleyes

Higher octane fuels tend to give a power increase if the engine is designed or setup to run them.
Best example of this was the spitfire. They managed to get more power out of it when they set it up to run on 100 octane fuel. i think it increased the top speed by about 30mph. OK don't sound much but i would like that little extra trying to out maneuver someone in a dog fight  :lol
