Mileage

[Pal]

I'm currently only on my first full tank, only having had the bike a week, and I know mine has the 22 litre tank, but I have 214 miles on this fill up, and the gauge is still on the quarter mark, if it makes it to 256 miles, that means four days of commuting on one tank, and 50+ to the gallon.
I really wasn't expecting this bike to be so economical, mind you there isn't much chance to wind her up on the crowded A3. And I do ride like an old granny to work as I need to make as cheap as possible.

The 600's regularly do 55-60 mpg and 200+ miles to a tank.
My personal best on one of my my boxeyes was 73mpg riding like Mary Poppins, and I was bored to tears!
Even riding her like a tw@ the worst I got was 49mpg keeping up with a few litre sportsbike mates.

You cannot work out a reasonably decent  MPG figure this way - i.e., looking at the needle .

A better way is to fill up at the station and make sure you insert the nozzle so that the handle is facing 12'o clock to 6'o clock, i.e. down the tank.

1. Stop at the station , Fill the tank up until the pressure valve in the nozzle stops fuel. Keep trying with pauses. Keep clicking that nozzle until not a drop more fuel can go in. Now ride your bike until nearly on empty
2. Reset your odometer trip counter; repeat (1) above AT THE SAME PUMP you used before; keep the receipt showing Litres used and total cost; write the trip counter value on the receipt; then repeat 1 above; take a note of the new trip counter and write this on the receipt.
3. Repeat 2
4. Now, for the  two receipts , work out the MPG FOR EACH as follows:-

a) divide the number of litres by 4.5 - the number of litres is on the receipt - this gives you Gallons of fuel.
b) subtract the lower trip counter from the higher trip counter; this gives you Miles travelled
c) calculate MPG by dividing Miles travelled (b) by Gallons (a)

do this for both receipts.

when you are ready, grab those receipts and - for each receipt - add up the MPG © and divide by the number of receipts you have (starting with 2); this gives you an improved average MPG figure. now you have a reasonably  accurate MPG. The more you repeat step 2 above [and a-c] , the better the estimate; ideally you should repeat until the average doesnt change but this is difficult because factors such as drag (tyres, wind resistance, you!), riding style, ambient temperature and so on ... will affect your MPG ... but you get a better number than just working of where your needle is from the last fill up.

Simple math mixed with some stable test conditions, as stable as you can reasonably get, but I thought it may be of some help ??

This is basically what sites like "Fuelly" does but the above method does not require you to sign up to a site and get spammed via email as they sell your email  address on - come on, you dont think you get something for free in this world do you

FIW , my average is 48MPG used on a 22 mile round trip commute, 5 days a week, 9 months of the year, on A, B and unclassified roads, same journey every time, 11 sets of lights on the journey so some stopping/standing. Rather sceptical of the claimed 65+ MPG I've seen touted , but hey if people want to claim it, why not ! what do I care

Or you could just use fuelly

Or you could just use fuelly

and get spammed and your details sold on , upto you, not me tho

Pretty much the same as most t'interweb sites you put your details on then :

Fuelly works for me, has done for the last couple of years.

[richfzs]

Jeez, talk about making things hard  :wall

Use fuelly (others are probably available). I get zero spam from them, thanks for your concern, but it's entirely misplaced!

[MC680x0]

Fuelly is fine if you want that unnecessary  tat - carry on using it - not everyone wants to do that and many people I have helped have found it easier and less worrying than visiting a "cull site" every time. Its all about choice. And equally "difficult" to use Fuelly - specially if the wife has the laptop or the net is down ! Its all about choice mate, choice, you do your stuff, let other do theirs  - jeez  :wall

[richfzs]

Your method is easier? Aye, whatever works for you...

The guy came on saying what good consumption he was getting, you've rubbished his analysis method (which is of course suspect) and given a complicated method for him to get better figures. Stevie and myself have suggested a much easier alternative - that's conversation, differing opinions, if you don't like that, forums probably aren't the place for you!

erm , steady on .. nobody has rubbished anything; I have offered a method which actually you then rubbished. Try to avoid conflicting language and accept that not everyone (including my humble stupid self) is as perfect as you and people may like to try a few alternatives to see which suits them; as you say, you find my method "complicated" yet my 12 yr old son is working this out on his motoX ??? so its all about choice and not your dictation;  - jeez calm down , its just a forum of ideas, views, opinion, trial and error , ideas and mistakes - just a forum -  :rolleyes

[stevierst]

Eh, eh, eh, calm down laaa.

It's just a forum fellas, were supposed to be having a laugh here, dont take it all too seriously ffs!

[MC680x0]

eh, thats our kid, where did you get his mugshot from - nice1

I was having fun  :lol but then it got all far toooooo serious for me so I'm just LMFAO 

Sorry - back to earth now

Note your using Fuelly too, 40MPG is far too much , you must be taking it slow on those lanes mate 

[stevierst]

It's me selfie innit maate! 8)

I TAKE IT ALL BACK (about Fuelly anyway) .. Last time I looked at the site was about 3 years ago; their privacy T&Cs have been updated and now read:
We will never sell or trade your registration information or spam you (you can turn off any/all email notifications in your user settings). Fuelly will not share such information with partners, affiliates, vendors, advertisers, sponsors or other third parties, unless required by law.
So they have improved from their launch state where they came under significant negative critique for spamming a few years back. Looks decent now. So I'll have to ditch the perm, retract the paper receipt method, and reconsider fuelly. what a waste of typing  :b

[darrsi]

:rollin

[MC680x0]

Yeah..anyway, Fuelly rocks ...  It's so useful...

[stevierst]

anyway, Fuelly rocks ...

Holy shit, thats impressive fuel consumption!

[tychris523]

why would anyone be this bothered about fuel consumption just keep putting the stuff in every 200 miles if its to much for ya get a smaller bike

My Thundercat is my grafter, and its just nice to keep an eye on the fuel usage.
I use my fuelly app to record consumption, fuel mileage cost, tyre changes, service reminders, etc.

I know if the fuel consumption increases, there could be something wrong with the bike, and I get some fuel mileage relief from work, so it's always good to note it.
And I'm a geek, so I like to dwell over it
