Wollies unleaded - 530.2 kms - 39.41 ltr - 13.45 kmpl - 7.43 ltr / 100 km BP E10 - 498.8 kms - 39.05 ltr - 12.77 kmpl - 7.83 ltr / 100 km Shell Unleaded - 535.1 kms - 42.15 ltr - 12.69 kmpl - 7.88 ltr / 100 km Yes the consumption increased slightly but note that I had not checked tyre pressure for months and all 4 were low and uneven. Have put 34 psi all around and filled up with Shell unleaded this morning. Will report back on this when I fill the next tankful Driving conditions and routes have not changed much. No other driver other than me. Mostly 1 person in the car, occassionaly 2. Liberal use of air con as well. Edit: With the latest consumption figures using Shell Unleaded. As can be seen, slightly worse economy than Ethanol. Interestingly, I filled up with 42.15 lts but I thought the fuel capacity of the tank was only 42 ltrs?
