So is that good or bad?
I can't do the maths.
What's the mpg?

I get about 45mpg on average. Tried some additives to improve it but nothing helped. I just drive it normally however and don't bother trying to extend the miles.

I did a run to Manchester and back last year for work and did a brim to brim check and managed to get 57.1 mpg but was pretty much all on half decent A roads and motorways. There were some that doubted the figures at the time but the maths couldn't be disputed.

"Round journey was 412 miles and i used 32.8 litres of diesel.
Now assuming my calculations are correct

32.8/4.55 to convert to gallons = 7.21 ish
412 miles/7.21 = 57.1 mpg"

My Contemporary will do about 48-49 at 70, and mid top end 50’s if driving like miss daisy.

I use an app called Road Trip to record mpg.. last top up was 36.8 with 40/60 motorway and city

I'm away on a break at the moment in Heacham Norfolk (was told when researching the Norfolk arm of the family to look on incestry.co.uk

Normal mixed driving sees the fuel guage drop one section (8th of a tank) approximately every 50 miles. Before leaving filled tank till pump clicks off as normally I do and drove the 88 miles to Heacham in one go and I still hadn't completely used the one section 50 miles does !!!!!!!

I know a run gives you better MPG but this seems dramatic. The ZT auto is either very economical on a run, or very thirsty on general driving, or both.

Both our Autos give us about 30 in daily use 22 with the Caravan on the back and high 40s on a run. Best I have managed with the Autos was when I was driving 72 miles to work it was motorway for 68 of the 72 miles. With a very gentile right foot I managed to get 62 mpg it was really nice to fill the car up and see a range on the on board computer of 876. Makes a change from the normal 448.
But it is my choice to have the auto box old age and a broken back some years ago makes it much easier to drive.
