I think a petrol engine is now a better bet than a diesel at any mileage.Fuel economy may be slightly worse,but engine running costs should be lower with less to go wrong on a petrol model.Diesel engines are far more complicated with not just the dpf ,but all the sensors and electronics that are associated with the diesel emission system.As for a euro car dpf,you may be better with a tin of beans.they do not perform to original makers spec.

True, but other things can go expensively wrong with diesels as they get older.

You may well find that a newish petrol S-Max is still cheaper than a diesel of the same age and mileage. I'd agree that petrol is the way to go, particularly if you intend to keep it for a long time. There may be fewer to choose from, though.

Edit - correction, you WILL find fewer petrol ones to choose from. If you look at card for sale on this site, there are 819 diesels and just 76 petrols. If your mileage is more long trips than around town, you should avoid DPF problems.

I think you'll find mpvs, due to their weight, drink petrol like fish, diesels much more economical, take official figures with a barrel of salt.
