Re: Miles per gallon

Thanks for your replys.

I have been using the incar computer to get the MPG readings which were averaging 38 - 40 MPG with steady lightfooted driving.

I have been running the car on Asda diesel and was advised to try a better make of fuel.

Today I decided to do a milage test by putting in 9 ltrs (2 gallon) of diesel as soon as the fuel light came on, making a note of the speedo reading and then taking another reading when it comes on again.

This time I used an Esso garage for the 9 ltrs and noticed on the incar computer that the MPG within a few miles had increased to 47 - 51 MPG with the same style of driving.

Two questions.

Do I trust the incar computer readout?


Is it true that a better quality fuel will give more miles per gallon?

I will run the 2 gallon test and let you know what milage is returned.
