Just filled the tank for the 2nd time. I made 526.4 km with 43.38L (or 327.1 miles with 11.46 gallons). That translates into 8.24 L / 100 km or 28.5 MPG.I'm pretty happy as I had got 9.14 L / 100 km (25.7 MPG) with the 1st tank.Both tanks were driven under the same conditions, 80% highway/20% city, never really over 65 MPH or over 3000 RPM.It may not improve a lot, but I still hope to be able to reach 30 MPG.
