I am looking for full articles/books that detail the process of
calculating mileage running costs for cars. What are data/formulas
needed to conduct such a calculation? Any comments/ideas are welcome.

Here is a good article:

Redhoss that's a very interesting article. Thanks a lot. 

Perhaps, I should've mentioned that I want the process of calculating
the costs starting from knowing how much does a kW of engine output
cost, i.e. for an internal combustion engine: 30$/kW. By knowing this
figure, how can I figure out the annual cost of the
engine/maintenance/fuel, etc. I am interesting in knowing the formulas
and data needed to carry out such calculations.
