As a 3.0d owner shouldn't really be posting here, but I used redex additive yesterday when i filled up and my consumption went up from 29.2mile per gallon to 33.1 mpg....I guess the additive must have done something as nothing else has changed on the vehicle, and the gas station and fuel i use is the one i always use.....
