Petrol Engine

    Would I be right to assume that, say for example on a 30km journey,

    I could expect 30 MPG / 9L/100km from a petrol engine, and that the size of the petrol engine does not matter from say 1.4, 1.6 or a 2.0 turbo litre engine?

    What I basically trying to ask is that the size of petrol engine does not matter (up to say a 2.0 turbo engine) they all give about 30MPG / 9L/100KM on a about a 30 km journey ?

    (say all engines are well maintained/serviced etc. assuming a constant speed of 100 km/h)

    Thanks

    Is this a serious question?
    The answer is no different engines have different fuel consumption. You have to take so many factors into consideration not just the cc.

    Tbh, the biggest variable is your driving style, in the city anyway.
    Drive like a OAP and save money, drive like a 18yo with a fresh licence and be ready to spend... ;)

    One of the main things to take into consideration is the size of the engine vs the size of the car. A 2 litre engine would be more economical in a car the size of a Mondeo compared to a 1.6 as the 1.6 will struggle to pull the weight of the car around compared to the 2 litre.

    Completely depends on engine, car and driving. Had a light jap 1.4 that would easily average over 40mpg, had a 2l Mazda that would average about 38 (good gearing for cruising). Had a 2l petrol SUV that would average 30 if you were very lucky. Her 1.6 petrol is averaging about 36 but that does more town driving than I would. Making a lot of assumptions but I'd say the average mpg for the average petrol car in ireland is closer to 40 than 30.

    As has been said, there is no black and white. It depends on the engine model, gear ratios, size and weight of car, type of driving, driving style etc etc.

    As a very loose rule, small petrol engines would be more economical in the city and larger would be more economical on longer/higher speed/motorway type use.
