I loaded about 40.71 liters of Petron unleaded a couple of days ago. Prior to that filling, i tanked up with Unioil from near empty and travelled 393.4 Kilometers. My aim is to check on what Petron claims is a superior unleaded gasoline that will provide better mileage than the others. Seeing their advertisement on TV that a car ran 1100+ km. on a full tank made me want to do this as i really do doubt that it was as they claim. Anyway, i'll update this after i used up this tank of Petron gas.
