I'm not sure that I fully understand the point of your question, 'J liddy'.
For what it is worth, my own approach is to break my motoring costs down into four categories; viz: Fixed (Tax, Insurance, MOT), Servicing, Repairs and replacements (Tyres, Battery, etc.) as well as Fuel of course.
By recording these on a spreadsheet, I can analyse and plot the results as required. I look for trends, which can indicate potential problems, rather than absolutes, which are useful mainly as a snapshot in time, for example, a holiday trip.
Interestingly (for me, at least) there seems to be a Pareto effect at work in my figures. When I was working, fuel costs amounted to 80% of my total motoring expenditure; now, they represent only 20%. Not all motoring costs vary with mileage but are now amortised over a much lower mileage. This, in turn, leads to a much higher cost per mile travelled. I won't frighten you with the actual figures, but it would probably be cheaper for me to take a taxi everywhere!
