TH Sports 4 speed auto...for the past 9 years (whilst my mum owned it), the average was 10.1/100km ( 9 years and 260,000km). That was driving from Campbelltown to Roselands and back 5 days a week and regular trips away etc. I bought the car about a month ago, and my average has been about 13.5l/100km. That includes a few spirited drives but the major difference would be that i tend to use it for short trips, ie 5 minutes at a time. Kids to school, local shops etc not the kind of driving that will give good economy.
