T Sport MPG First Car

[umarji95]

Hi there, I'm new to owning a Japaneses car. I am into German cars, however I fell for the T-sport when it was recommended to me as a first car.

Anyway, I picked one up for £1100 2 weeks ago. A sweet nippy car, however there was one thing I released straight away. I am doing half of what the MPG is suppose to be.

I topped up £20 (half tank) - I only managed to do 120 Miles.
Second time £20 (half tank) - I managed to do 140 Miles Improvement

Gave the car a full service
Third time £20 (half tank) - Still doing 140 Miles



My Yaris is a T-Sport 1.5 Petrol, 2003 model. Currently done 83000 miles on clock.

My friends is a 2001 Y reg, Yaris and he does £20 to 300 Miles!!! Currently done 110000 on clock.



PLEASE HELP!
[I AM AN ECO DRIVER + Tyres, etc all in good shape]
