The attachment is an Excel file you may find useful. It will track your fuel use. Fuel Consumption.xls Note: each time you go to fill up your petrol tank it will need to be full. Things to do before you start using the spreadsheet: 1. Go fill up you vehicle with petrol and take note of your ODOMETER, the DATE, and the type of fuel you used. 2. You will need to enter some information in some cells. Cell B1: the DATE from 1. Cell E1: the ODOMETER from 1. Cell H1: the colour of your vehicle (yes the colour of your vehicle effects your fuel consumption) Cell J1: Build Date Cell L1: Wheel size Cell N1: Tank Size (which is of course 70 Litres for an Aurion) Cell P3: Fuel Reference Number* from 1. 3. Now you will be required to fill in 6 cells each time you fill up So each time you fill you will need to record the ODOMETER on your receipt Column A: Date Column B: Location Column C: Fuel Reference Number* Column G: Odometer Column H: $/L (Note: $/L not c/L) Column I: Total Price Now this Fuel Reference Number can be found in cells Q293:Q312 For example if you used BP Ultimate the Fuel Reference Number will be 8. The only cells that have user input are the TAN coloured cells. In columns D, E, F, J, K, L, M, N, O, P are formulas that shouldn't be touched for the first few rows up to Row 5. After that each time you enter your weekly data, you will need to highlight the cells above and drag and copy the formulas to the next row. ie. highlight cell D6:E6:F6 the drag the bottom right corner to the next row, and the similarly for J6:P6. 4. There is an optional input for cell D294, this is where you enter your next service ODOMETER, and in D296 will be approximate the date of your next service schedule. 5. All the information below Row 292 should be self explanatory Note: You will see some N/A or $DIV/0! cells these are normal. I hope the above instructions are clear enough. Have fun! If you do use the spreadsheet, it would be great if you post up your spreadsheet regularly (every 10000km or so) in this topic, thanks! Note: I have been using the same spreadsheet for over 3 years, and all works well, but i did have to do some modifications to the spreadsheet before posting it. Due diligence has been taken to ensure there are no errors.
