My TD5 manual is pretty amazing on fuel now.
When I first got it at 18k miles it was doing about 26/27 mpg steady
I blanked off the EGR.
IMMEDIATELY, the car ran better, and the mpg went up to 31/32.
On long runs using cruise control and steady speeds about 56 - 60 mph, it can easily hit FORTY miles per gallon.
Over all, including a little off-road and rough stuff, and some heavy trailer work, it is still averaging well over 30 mpg.
As far as fuel consumption goes I'm pleased with the TD5.
