1997 300Tdi manual, only had it 2 months and doing 72mile commute round trip a day near lake district, I keep it below 2250rpm and filled to brim twice and worked out I am getting 36mpg. I bought it for the winter and due to the fact you could get mid to high 30's in the mpg stakes, so far i am well pleased as my 3.0TD Landcruiser will only give high 20's due to being auto.
