Question: what is the difference between 1.8 l and 2.0 l engines?
Answer: A well-cared-for 2.0-litre engine, driven well will turn in much better fuel economy than a worn-out 1.8-litre engine driven poorly. ... A larger engine would probably make more sense, it would work less hard, the car would feel less underpowered, and the engine would last longer.
