Hi, 7.8 is based on trip computer - but also verified by fill-up...

I only get it this low on a constant highway drive, which is typically Canberra to Sydney and return, and the occasional run up to Port Macquarie or to Melbourne.

I record every refuelling in a spreadsheet with the amount of fuel used to fill up, so it works out the last tanks economy each time. The only rule being that when I refuel, I always fill to the top.

My MD Mondeo is a petrol, not diesel... my previous drive Peugeot 508GT was a diesel.


In the life of my Mondeo, since Dec 2016, I have used 6,646 litres of 98 petrol, which cost $9,432, so average at $1.42 per litre, and average economy of 10.58L/100km.

This compares to my Peugeot 508GT June 2012 to Nov 2016, in which I used 9,511 litres of diesel, which cost $12,673, so average at $1.33 per litre, and an average economy of 7.77L/100km.

This means the Mondeo petrol is 26% more thirsty on fuel than the Peugeot Diesel.
