Hi Paul,

A figure of 24mpg equates to 11.77 litres per 100km. That means that you'll burn through roughly 14.2 litres of fuel every time you do 120km. At today's average fuel price for petrol of 147.9c per litre, that means each 120km trip is going to cost you €20.88 in fuel.

Of course, that's also assuming that your Lexus is going to do a constant 24mpg all the time while you're on your 120km journey, which it won't. Hopefully the average will average out, but depending how you drive, what the traffic's like and how many hills you have to go up or down, you could land a bit either side of that figure.

Hope that helps
