Car Cost of Consumption from real owner

This is the research that have done by my friend regarding fuel consumption to types of car available.

The first graph is "How far you can travel for a Ringgit?" (higher better) (on RM1.92 per liter)


This second graph is "How far you can travel for a liter of petrol?" (higher better)


The third graph is "How much it cost to travel a kilometer?" (lower better)
