Update : Did 88.3 MPG this morning, wich is higher than my best morning, afternoon and AVG for my commute.
On the returning trip I did 89.7!
I filled up on the way home. Did 689.7 mi on 9.565 gallons (us). Wich equals 72.15 MPG | 3.26 LHK (FCD says 73.7 MPG | 3.19 LHK). Pretty happy with it since its my first tank with the car. Next tank will be way better, tomorrow I'm going to install my new Bridgestone Potenza RE92 165/65R14!
Next on my to do list is :
-12V grid charger.
-upper grille block.
-new rear shock absobers
-750 mi tank!
