Actually, how much can we truly save with a fuel-saving car?!

I told him to stop joking because there’s no way he can save more money. He was a little offended. He challenged me to tell him my fuel consumption. Well, as at today, it’s 7.3 litre per 100km. That’s about 1 litre of RON95 petrol to 13.7km. His awesome car could give him nearly 20km to 1 litre. I did not bother to ask if that’s solely on highway because if it’s just highway, my Persona could also do way better than 1 to 13.7km. Anyway, he laughed at me and I laughed at him and I guess we agree to disagree.
