30.7MPG!!!!

[alex160]

sorry going to have to disagree a little unless i'm missing something 51.90 should have been divided buy 4.55 (1gallon=4.55 litres) to give 11.40 gallons so 315.4 divided buy 11.40 =27.66 mpg which is about what i average out of mine as i said please point out if i have just made a total c*ck of myself

 

The trip computers are good but they aren't aren't 100% accurate.
I brimmed my last tank with v-power which took 51.40 litres then when the petrol light came on i brimmed with tesco 99 which took 51.90 litres.

So i clocked 315.4 miles and used 51.90 litres

51.90/5.54=9.37 gallons

315.4/9.37= 33.7mpg 

My trip computer was reset at the time of fill up and after the 315.4 it read 31.9 (on mode 2) so you could all be getting even more than you realise 

Any hows i'm doing the same test again with the tesco 99 fuel to see which is best for my pocket and yes i am tighter than a submarine door 

 :embarassed: Your right 1 gallon does = 4.55 litres so my bad there, 27.66mpg how depreesing mines not even quick 

Sale it on mate, buy something with some power.
