Mazda6 diesel or petrol Megane?

I am looking at buying a used car. I travel up and down to Drogheda from Dublin each day for work. Would a 2.0-litre diesel be more efficient than a 1.6 petrol? They are both 2007, diesel is a Mazda6 and the 1.6 is a Megane.

Hi Jon,

So, your average mileage is going to be around 25,000km per year. That’s just on the cusp of needing a diesel, so I’d suggest going for the Mazda in this case, as it will be much more efficient at that kind of journey, and the constant long motorway runs will keep the particulate filter in good order. Plus, the Mazda will likely be more reliable than the Megane in the long run.
