Miles per Litre
« on: 31 January, 2020, 01:42:43 PM »
I am assuming that my CBF1000-FAB (2011) is incapable of displaying average miles per gallon, it displays AV Miles/litre and I've pressed the various buttons and looked at the owners manual and it doesn't seem to be an available option.

In terms of fuel consumption, what figures do people get? I have a current AV of 12.8 miles per litre. What do people do to convert that to MPG?, I've been multiplying by 4.5461 but is that correct? It gives me 58 MPG (on the few occasions I remember to do it based on full tank to full tank at the petrol pump I get less than 55 MPG)

Thanks
Steve

Being lazy I'd multiply the liters by 4.54 and 58 mpg's isn't a shabby number. 50 to 55 mpg is about where I am with my 2006-A6

Correct, alas no MPG.
Also right, x4.54; but I find it keeps the grey-cells active if you are interested (it makes no real difference to a fair-weather ride but is 'of interest').
However, I cheat at this exercise (having lost more grey matter than I'd like) and find multiplying by 9 and then dividing by 2 can be done in moderate traffic - at other times my attention is not on that display.

58 is very good, steady commuting?  or are you not trying !
You do have to take a very long-term average to do this justice - over 2,000 miles before the numbers start to settle down (unless you are measuring the cut-off points very well).
Only do it right - no bodging please.   Keeper of the failed stator list.   John.

I am commuting most weekdays, covering about 500 miles per week (A12 and then through central London), I am not exactly screaming away from the lights but I don't hang around unnecessarily  :001:

I tend to check the average each week, at the weekend when I clean the bike.

I’ve got a 2012 FAB, when touring I often get over 13 miles per litre.

My wife rides a CBF600SA and keeps my speed in check.  :002:

I guess I must ride my 2016 Mk2 very gently as I get 13 point 6 miles per litre

I normally think:

10 mpl = 45mpg
11= 50 (round up)
12 = 54 (round down)
13 = 59 (about right)
14 = 64 (Nearly)

Anything more and I just open the throttle a bit as I am obviously not trying
