The best I have got out of my 19td Xantia is 700 miles on a tank. I
used 57 litres so I should have had about 8 litres left when I filled
up. So averaging at 55.75 mpg I could have made nearly another 100
miles!
This is all motorway driving, nice and smooth.
I normally average around 52 mpg virtually all motorway driving.

That was driving at about 60mph on average. But it all motorway
driving 40miles journey each way. If I do a few small trips into town
on the same tank my mpg will drop below 50 mpg. But i have also
included a longer trip of about 200 miles driving at 80mph and still
average 51-52 mpg out of the tank. I find shorter urban trips will
drop the mph drastically. I think the secret to getting a good mpg out
of a tank is simply long journeys at a constant speed without braking!
And of course keep the car well serviced and check the tyre pressure.

Anyone had any experience of adding veg oil to their diesel?
