Engine  and the fuel consumption of its cars there is a certain Differentiated.

      In the car, motor vehicle and the adaptation of how the fuel consumption of motor vehicles have greatly affected. If there is a practical example shows that the emissions of small engines adaptation of the well, may not be very large displacement than the fuel-efficient engines, or even than the large displacement of the engine for oil. In particular the dignity of the heavier vehicle, if the engine displacement is too small, with small Mara Crane is bound to make the engine more in high-speed operation under the load, which consume more gasoline. If the configuration is the largest displacement of the engine, the more torque, do not have to tread very deep under the accelerator pedal, the consumption of petrol a little change. By comparison of the results, may be small displacement engines for more oil.

     So you in the selection of vehicles, not just to look at the engine displacement.But also from the car, and other aspects of the forces considered.
