Should I stick with diesel or change to petrol?

I drive about 10,000 to 12,000 mls per year and drive a diesel with DPF. I am thinking of changing my car, would it be more benefical to stick with a diesel or change to a petrol engine.

Clearly the type of driving that you do suits the DPF regeneration regime otherwise I guess you wouldn’t be considering another.

Comparing petrol and diesel running costs isn’t straightforward.

Diesel cars cost more to buy (new or used) and while fuel efficiency may be better, diesel does cost more, currently around 5p/litre more.  This means that it can take a long time to recover the additional purchase cost and break even – Glass’s Guide estimates that you’d need to be doing at least 10,000 miles a year on average.
