Fuel efficiency is a subjective topic. It depends on driving habit, conditions and vehicle. If the vehicle is quoted at certain mileage per liter, there is nothing much you can do to improve on it except to have good driving skills and that involves the accelerator pedal. Steady and gradual acceleration helps on fuel economy.
Ensure the engine is correctly tuned.

I am not sure about that but where sparks plugs are concerned, you need to follow the manufacturers recommendation to get the best result.
Some plugs might be different and you need to be sure that it is equivalent to what is recommended.
