Thread: Petrol v diesel economy

Back in the day, possibly incorrectly, I worked out that if the fuel mileage was the same then it took quite a few thousand ks before the diesel started to beat the petrol
Considering 2000-2010 model 4wds, (the models I am likely to afford one day), are they comparable or are the petrol models just to poor?
Some of their prices are good but there may be a good reason for that.
I do know my 3.2 by bighorn liked a drink but by the same token my current 2.8 lwb pajero is nudging 22mpg which isnt that great
