Exactly Gooner mike. I was noyt wrong, this was just when it was more of a difference, and the models I prob choose wern't the best comparison 
25mpg is 15.6ppm (petrol)
40mpg is 11.0ppm (diesel)
So in the diesel you're 'saving' 4.6ppm at these fuel consumption rates.
Tried working out the MPG manually yet? You'll be surprised at what you get with the 1.8T!
Done it twice and averaged 36MPG!
I reckon you need to be doing 25k miles a year to make a derv equal it's petrol equivalent. anyone care to add to this.
So If my maths is correct a 40mpg diesel car vs a 25mpg petrol car over 20k miles will save you a grand
I reckon a diesel car is normally £1700 extra to buy if you buy a year old one.
factor in the extra tax on a petrol car for a year (£100)
I reckon you need to be doing 25k miles a year to make a derv equal it's petrol equivalent. anyone care to add to this.
I think the wee computer in the dash is either being optomistic, or lying half the time!
I think it's just ~25k in the lifetime you expect to own the car rather than per year.
youll see when u sell your petrol like i did!
Gotta be from an auction/finance repo.Way,way below book.
I might even consider one at that price.![]()
Mate, this Ibiza is not my first car, I have been driving nearly 21 years and I have had both diesel and petrol cars. In fact at the moment I own and drive both. The other one is a 150 CDTI 2007 Astra on 63k miles so far.
