MPG doesnt match actual fuel consuption,a little help please

[jedi-knight83 0]

Got a 95 VR6

 

i reset the MFA 2 thing (the one that keeps going even if the car is off for more than 2 hrs.) when i fill up.

 

the MPG shows about 26 since filling up and yet im only on about 270 miles and the tank is almost empty.??

 

i always fill up to the top with optimax. 26MPG for 15 gallons is about 390miles is it not?

 

why am i getting only 270 to the tank? (prob be about 280 or 290 before i actually fill up) On this tank i have done a few longer trips and a bit of town driving.

 

is there a fuel leak and how on earth do you find it if there is one??

...and the tank is almost empty.??

 

 

 

Going by the gauge? They can be quite inaccurate and even when showing below empty you can still have a good few litres left. How many litres/gallons do you get in to fill it back up to the top?

last fill up was 58 litres and that indicated as just above the red.

Fuel tank capacity is 70 litres so you'd have had another 12 litres (just under 3 gallons !!!) left :-)

70 litres!!!!! i thought it was only 60-65 i guess i could put a can of fuel in the boot and run it till it starts getting empty just to see how far it will actually go.

 

what are your normal mpg and miles per tank?? does mine sound particularly bad??

 

 

oh bummer, just seem the caps but cant be bother to re type. sorry

mines usually around the 30mpg, and I get 300 miles before the needle reaches red, and I refill :)

 

that usually costs 35 quid to fill back up again, I never check the actually amount of litres going in cos I am lazy and can't be bothered to move my eyes slightly

300 miles for £35 is loads better than i get!

 

could there be a problem with my car? i have just had the injectors cleaned at the last service.. im reluctant to disconnect the battery so as to reset the ECU cause i dont know what the alarm will do (see my thread about TOAD Ai606, i dont have the code for it)

Hi I have the same alarm as you and have disconnected the battery on mine many times. Not sure what you mean about the code and havent read your other post so this may be of no help but you never know
