I went to your website on real fuel figures and found that it is based on a month's consumption. My figures are based on 20,100 miles since new in a VW Passat CC 1.8 TSI. Overall consumption works out at 38.22 mpg. This includes 9,000 miles in France with half of this at 130kmh cruising on autoroutes; the rest in mixed driving in the UK. The onboard computer consumption readings are about 5% optimistic. Petrol consumption is now some 7% better than in the first 5,000 miles. I added just under half a litre of engine oil at 450 miles and the same amount at 3,600 miles. Since then the oil level has remained unchanged between the two oil changes undertaken.
