We did a couple back to back weekend runs to Lincolnshire in our 20 year old FSI (86k on the clock) as our family bus is currently off the road. First time it’s been on such a long journey for us - I made sure the AA membership cover was adequate in case hut it did not miss a beat and we were so impressed with the fuel economy. The first weekend run we averaged 49.6 MPG over 320 miles and the second weekend we averaged 49.7 MPG over 360 miles fully laden with four people and some bags. We travelled mainly A1 but with some slower roads mixed in. Looking at some older threads from 2006 on FSI mpg, owners were reporting 50 MPG on motorway runs and so for the car to still be achieving they 20 years on and with 86k on the clock seems incredible to me. I wonder whether the MPG is boosted by the proboost ECU or whether other FSI owners experience similar economy?
