Assalam-o-Alaikum,
I have been using my sheets for measuring up/downs in fuel consumption with good graph, overhead/repairs and maintenance history, as per below excel file.
Click save file to PC option on below page,
2shared - download Car Maint.xls
Certain members post their consumption and calculation regarding performance, Rs/Km, Km/Kg, Costs etc.
Do we track the trend analysis of our vehicle and point of deviation, performance after certain repairs etc.
