mpg ?

[rac]

hi all

how many miles to a gall . 4 .5 litres.

been using the trip . with the fuel light just starting to come on put 5 litres in done 42 miles and its starting to come on again ,it started to glow going up a hill as soon as it leveled out it went out . do this fuel lights on the mg's stay on bright when it starts to get real empty. reserve is 5 litres ?. cheers rac .

Around town I average from 34 to 38 mpg driving mostly to and from work. I recently covered 2,000 miles in 4 days and rode 70-75 mph on the Interstate for one tank and actually got 50 mpg on my 2002 Scura. That was a first for me. I rode like a little old lady from Pasadina. That was a first and likely a last because I drive much more aggresively normaly.

Rac, my fuel light has never worked from day one, I rely on my tripmeter. My average fuel consumption from new is a smidgen under 40mpg. A high of 46 and a low of 36. I generally target 150 miles between fills but never more than 170. I have put over 21 litres into my tank twice. So when it starts spluttering you know you have about 5 miles to go, more fun than a fuel light in your face.

with Ti cans and ECU I used to get 52 British MPG, ridden in economy mode 56. John in Leeds used to be about 5mpg less for the same run at the same time,when we had runs out. Fuel light worked when it felt like it, so relied on the trip meter and filled at 150 miles

The low fuel indicator is not a calibrated device. Well, it might have been when installed but the floats have a tendency to change buoyancy so you really can't rely on it except that it indicates when the tank is not full. The tripmeter is only as reliable as the operator, but at least it's accurate if you've got a good idea of your riding style and your particular bike's fuel economy. FWI, my V11 Sport would hit 51 mpg on a steady drone up the freeways in the middle of California if held at a very steady 79 mph. Around town, it was more like 44 mpg and for the infrequent blasts in the mountains it would drop into the high 30's. That same bike, now that my son has it and it's been optimized to run really well, is running in the high 30's all of the time.

I get anywhere from 30 to 37 MPG.

30 on short fifteen minute commutes.

35 riding through canyons. (most of my riding)

37 on freeway.

 

Here are some conversions so that some of you might understand what we yanks are babbling about, and vice versa:

US MPG		Imperial MPG				  km/l		 miles per liter
30				36.03					12.75			7.92
30.58			 36.72					13
32.93			 39.55					14
33.31			 40.00					14.16
35.28			 42.37					15				9.31
37.63			 45.2					 16
40				48.04					17.01			10.56
41.63			 50.00					17.7
42.34			 50.85					18
44.69			 53.67					19
45				54.04					19.13			11.88
50				60.05					21.26			13.2

Good initiative, but AFAIK noone use the rightmost two ways of telling it. For metric people, the table should have a "l/100 km" column as that is what we use (Actually, in Sweden we mostly talk about "l/10 km" but that conversion is not very hard )

 

Are NZ and AUS using the british miles and gallons?

DARN!

Thanks.

I pulled up a conversion tool and ran the three options that they offered and then manually calculated in the miles per liter as some seem to use that.

I'll fix it.

hi all

thanks for the response on the mpg ,so to round it up 35 to 40 to a gall or 9 per litre. as for the fuel warning light ,you can take a chance with it then , maybe it will work or maybe it won't .emmm . think i will try for a few weeks by just putting enough to go to work and back 40 mile round trip . quite nice not to have a full tank of fuel sloshing around beneath you .bike is a lot lighter too to move about in tight spots . thanks again .rac .

Thanks, now I can relate. I've had varying consumption depending on ECU and map. Worst was around 33 mpg [uS] with OEM ECU and best was better than 45 mpg with My16M and Nigel's map.

I've ran out of fuel twice on motorcycles. First time was long ago on a carb bike, I had forgotten to turn the petcock away from reserve, so when I ran out of fuel it was no reserve left. Second time was plain stupid, I was playing gas-station-roulette and lost it. My stupidity was triggered by the fact the fuel light goes on too early. That particular time it went on at some 160 kms on the trip, and I was stranded at around 280.

Since then I always fill it up after passing 200 km on the trip if the fuel light is on. If not, I would do it anyway before reaching 250. On long trips I use to make a short stop at 100 kms and a longer gas stop at 200. Then I don't care much about fuel level, I need the pause anyway.

 

Also, I noticed it stays out much longer on twisty roads, with gasoline washing around in the tank.

On my 2001 the low fuel sensor is a thyrister and I assume this is the same as all the V11's ?

The thyrister only allows current to flow when it gets hot so if its covered by fuel the light is off (this is why LED's don't work here as they don't draw enough current to warm the thyrister),if the fuel is low it takes a few seconds to fully warm up so the bulb gets slowly brighter(but at least it doesn't flash madly like a float sensor would).

 

I haven't worked out my MPG but on a trip through France with pillion and luggage my friends 850 Lemans II (solo with luggage)was about the same which seemed pretty good to me !.

[docc]

The sensor is also voltage dependent. When I changed to the new battery the light comes on much sooner (0.4 USG sooner, or about 2 liters sooner).

[dlaing]

I like charts:

Guzzi Brevas do OK, helping make Guzzis one of the more fuel efficient bikes. The V11 spine frames don't do quite as well.

BMW F650 and F800 do very well, as do many Harleys.

I am surprised so many of the big air cooled twins out perform water cooled fours.

I live and ride at high elevation (7,000 ft above sea level), so my bikes typically get better mileage than others'.

 

With the Tenni I typically get 45-55 MPG (miles per US gallon), as indicated by the tripmeter, which is 99% accurate, as checked with my Garmin GPS 12 with a 3 meter accuracy. I have gotten as high as 60 MPG on a trip this past summer in SW Colorado, at road elevations of 8,000-11,000+ feet and ambient temp of 85-90 deg F.

 

My low fuel light consistently begins to light at 3.6-3.7 US gal, after which I have approximately one US gal remaining. I have put 4.7 gal in the tank after the engine was occasionally sputtering.

 

The best mileage we get on our machines is the wife's '00 Ducati Monster 900ie, which averages 60+ MPG.

 

When I was in SoCal for the campout in early June on the Tenni running 80-90 MPH splitting lanes on the freeways I got 45 MPG.

I am jealous.

What is your state of tune?

What do you set tappets and TPS to?

Is the airbox stock?

Are the mufflers and crossover stock?

Are you using a PCIII, and if so, what map?

What octane fuel do you use?

And last, but not least, how big and fat are you?
