Petrol or diesel Skoda Octavia?

Would a 2018 1.0-litre petrol Octavia cost much more in petrol costs than a 1.6 diesel to run in a year, when I will be doing 16,000 miles approx?

Hi Donal,

Well, fuel consumption depends very much on your own driving style and where (and to an extent when) you do most of your driving. That said, in general, we wouldn’t expect that 1.0 TSI engine to be much thirstier overall than the 1.6 diesel. In our tests, both engines are in and around as economical as each other and you should expect to get around 50mpg from either with a light foot. The diesel may be a little better than the petrol option at a sustained high-speed cruise. However, with such low annual mileage, we suspect that the petrol engine will cost less to maintain in the long run. It's probably the best option for you.

Hi Donal,

As Neil alluded to, there isn't a black-and-white answer to this for you as your mileage is in the middle ground. It boils down to how much of that is spent at a good speed on the motorway or open road. If it's less than approx. 20,000km a year, I'd expect the petrol model to work out cheaper in the long term when you take into consideration maintenance etc, though the diesel will undoubtedly be a little more economical at speed.

Hi Neil,

Thank you for your answer, but its 26,000km that I will be driving. I should have put it up as km in my post. What do you think would be the maximum amount of kms I could do before it wouldn't work out economically worth doing?
