For Diesel vehicles we expect to see improvements in fuel economy of
around 10%. This means if you currently get 50 MPG you might expect to see
somewhere around 55 MPG. This is very dependent upon your driving style.
If you use the extra power and drive faster naturally the economy benefits
will be lessened.
