MPG (working it out)

[CrypticCrud]

So I filled up the tank, paid 4 quid & out of that I got 124 miles.

So 4 quid is 3.055 litres at 130.9.

So if I divide 124 by 3.055 I get 40.58 miles for 1 litre (near enough)

And if I multiply 40.58 by 4.54(a UK gallon) I get 184mpg.

Have I got that right?

It is a Monkey so the MPG could be right but my math(s) ain't so wonderful. (read that as thick as fuck)

Your help is appreciated!

Seems a wee bit optimistic to me
Looking at Fuelly, the average mpg for a Honda monkey is in the low hundreds

Your first line is a bit vague
filled it up from what? bone dry of just low?
then 124 miles to what? bone dry or low?

You really need to fill it to a fixed level, ride it, then refill it to the exact same level preferably at the same pump noting the mileage.
Even then, all this depends on the accuracy of the filling pump and odometer.

Whatever, you do seem to be getting good MPG out of the thing

Honda claim 1.5L /100km for the 125cc monkey bike. In English this equates to 188mpg (UK), so yes, both your maths is correct and your MPG is entirely possible. I've also got to admit that someone actually getting anywhere near what the manufacturers claimed figures is a miracle. Well done.

The low level light is not an accurate indicator of level
it's just a well.. 'indicator'
Mpg is a variable, not a constant, but with this in mind
doing the mpg checks does help to tell us if our engines are working efficiently or not.

I wonder if the stated tank capacity has used the US gallon of 3.7summat litres instead of the UK's 4.54 litres?

Yes you are tight arse
3 feckin litres?
My last fill up for the van cost me over a hundred quid

Agreed. All of our info is on the web one way or the other, including my own site!
