Anyone want to take on this challenge?

at 23mph you are doing 125mpg

How much fuel is being burned per minute?


Thanks

I had a Rover SD1, at 140 mph it used over a pint a minute.

metric please....

Assuming UK gallons/pints that would be 0.0139383177 litres

or 14ml right?

How did you work it out? It just confuses me.

5.435 hours per gallon
0.184 gallons per hour
0.00307 gallons per minute
0.014 l per min
= 14 ml per minute

I'm too old for metric

125mpg, at 23 mph, it'll take 5.43 hours to drive 125 miles.

That's 326 minutes to use 1 gallon of petrol

1/326 equals 0.003066 gallons per minute

8 pints to the gallon

0.003066 x 8 equals 0.025


125 mpg equals 27.4967 miles per litre

so 23/27.4967 equals 0.8365 litres per hour

or 0.0139 litres per minute

That's roughly how much a 2004 Punto 1.2 uses at idle then.

I am lucky to get 28mpg @ average speed of 15mph around town lol, of course a lot of stop and start at that
