Well I run the devils's fuel (diesel) in 2 vehicles,

1. Transit, because you basically can't get a petrol one now, and it's big, heavy, engine has loads torque, and does long distance mainly so suits that.. It's also mapped so has a bit more go that average vans
2. The BMW is also diesel, 530d but again I mainly use for long runs of 200 miles or more, it does come into it's own for a mpg and performance combo no petrol engine would come near.... the overtaking torque is hugely impressive (also mapped , well over 400b/ft torque) plus I do run about town in it, shortest regular journey is 6 or 7 miles.

As mentioned, for short distance or traffic heavy commutes, then stick with petrol. If doing over 10 or 12k of mostly highly mileage per annum then a diesel 'could' be better.

Given the choice I'd always stick with petrol, but for pure torque in a heavy vehicle looking for economy, diesel has it's place.
