But anyway. I would completely agree that the financial justification for diesels are diminishing. If you can get 40+ out of a 1.8 petrol, why would diesel be an option given that the car is more expensive to buy, fuel is more expensive per litre and fuel economy isn't a million miles better.
What do 150 CDTi users get on motorways, 48mpg??? even 50 mpg?
So on a cost basis, petrol at my local Asda is 92.9p / litre, diesel is 106.9p / litre.
So over 10,000 miles (assuming no changes to fuel costs)
diesel uses 200 gallons = 909 litres >> £963.50 (50mpg)
petrol uses 238 gallons = 1082 litre >> £1005.31 (42 mpg)
A difference of . . . . . £41.81 - - - is NOT A LOT over 10,000 miles.
So over 30,000 miles thats only £125.43. How can that ever justify the extra initial costs, even though residual value will be slightly higher?
