What is it about petrol that interests you. You have done a considerable distance in your vehicle, which should give you a fair idea of the pros / cons of diesel. My feeling is that petrol, like diesel is only going to get more expensive but :-
1. A tank of diesel will get you further than petrol.
2. Because the engine has more torque, running the air conditioner is less noticeable in a diesel.
3. Diesel lends itself to bio fuel supplement / replacement in the future, although a satisfactory alternative is not available yet, according to the handbook. Who knows what may be offered in the future.
4. A diesel engine can be chip tuned for even more power, (Apparently).
Just a few things to ponder over.
Cheers.
