 In 3 years I've put 90,000 miles on it. I do not get below 500 miles per tank average 40 mpg city and as high as 58 hwy. There is a relief button inside filler neck of fuel tank to allow more fuel. I've gone 758 miles on one tank of fuel. Memphis TN to Madison Wi straight! Only problem with it has been glow plugs. Luckly I live in Ca so I'm not going to replace them. Other than that, expect to pay $900 every 80K for a timing belt. I'm getting ready to have 2nd one installed soon. I will buy a tdi again without a doubt.
