It's my car. It currently hosts the whitestar equipment. It's a 2006 Toyota Corolla with a 1.4L Diesel engine. I have been collecting fuel consumption data for a while now and I have compiled a chart to summarize the fuel economy of the car as a variable of the average speed for each trip. This allows to easily distinguish between in-city and highway driving.

Also there is an MPG chart more useful for US-based viewers:

In the interest of full disclosure there is also the input data and gnuplot script to generate the charts.
