Hi hydeco,Over the past two days I have I have noticed my kms to empty read out has been dropping like a rock! There are not error lights and no puddles of fuel under my car...
I do something similar in a spreadsheet on my computer. I keep a notepad in my glovebox and jot down mileage, gallons, cost per gallon and the date, then transfer that to my computer every couple of months.I have my own database for each car to log all costs. I can derive cost/mile (with or without purchase price), miles/day, low/average/high MPG and more. Separate reports for mods, service, fueling, etc.
I derive all MPG from the gas receipts - never rely on the car computer.
i have a new ford fiesta 1.6 powershift, has around 350 miles on the clock. im averaging only 17-20 mpg.. should i be concerned that there is something wrong with my car? your feedbacks are greatly appreciated.. im starting to worry..
