De-hyundrated

I have an April 2009 Hyundai i10 Comfort automatic returning 22-30 mpg. My dealer says this is because the engine is still tight (only 1,400 miles to date) and another dealer says it is due to my short journeys (usually 2 miles there and 2 miles back). Neither dealer has heard of the brake binding problem mentioned by you in a recent answer and also in the carbycar reports. What should I do?

If all you do are 2-mile runs then the engine will always be running on enriched mixture and your fuel economy will be poor. If you want to find out what it will really do, fill the tank, take it on a 200-mile run, then fill the tank again and do the sums on the basis of fuel used. Another reader complained of the same thing and was taken out by a Hyundai mechanic who averaged 58mpg over an hour in the same car.
