So I did my normal run of approx 200kms, with just water. Normally I see 5.5-5.6L/100Kms. This time I saw my lowest recorded ever for the Kia. 5.3L/100kms.
Not scientific, I know but lowest ever recorded is pretty darn amazing! (Im taking the win).
EDIT: I pumped my tyres up to 44psi (max sidewall). So this would have added to the economy as well.
