I bought a GD petrol i30 Active auto and have travelled about 2000km.
I have kept a record of km covered and litres used. The pump fuel comsumption however, does not equate to the figures the trip computer gives out. I fill up when the mileage to empty gets down to 50km or less and reset the computer at each fuel refill.
While there may be slight discrepencies when refilling, that should even out over 1500km. I have found that the trip computer under estimates the consumption by around 8-10%.
Some people may find this error acceptible but when prospective buyers often base their choice to a significant extent on ecomony, I find it misleading if not deceptive!
