Yes, Gazza, there's a premium on diesel vs. gasoline (you call it petrol) here, too, although these days it's less than about 10%. Even so -- there's still a cost benefit for running a diesel, and there are also driveability reasons for running the diesel (at least in our pickup, towing a trailer). Far less downshifts when climbing hills (maybe two or three in 1,800 miles, vs. dozens of them on the gasoline rig that we used to have), less engine roar, and so on. No question in my book -- another diesel when this truck gets traded in.
