Depends how many miles you do. New efficent petrol engines will work out more cost effective if you're doing less than 10,000 miles a year as you never make back the extra cost in buying the diesel in the first place.
At 10,000 to 12,000 a year there is very little in it either way. Over 12,000 you wan't a diesel.
Obvioulsy only by properly breaking down the figures with a calculator and knowing the MPGs and having a fixed price for fuel (which we wont ever have) could you know exactly, but that's a rough rule of thumb i go by.
There's also the residual value to think about throwing another spanner in the works.
