I do 15,000 miles per year - should I go for petrol or diesel?

I do 15,000 miles per year and almost never do less than 30-mile round trips. I would like a diesel but think I'm on the cusp mileage wise. What do you recommend?

As long as you run on Super diesel you're unlikely to promote sooted up EGRs or DPFs, but will eventually have to contend with a worn out EGR, a DPF full of ash and/or problems with the AdBlue heater if the car has an SCR system. You can get 50mpg from a decent petrol engine these days, such as a Peugeot 308 1.2 Puretech 130, so it's whether the additional 10 - 15mpg from a diesel outweighs the potential eventual problems.
