I get about the samebryno said:With my T31 173ps I get 38 mpg average in a mixed selection of driving. We tow a 1370kg MPLM 1143kg MIRO van which I estimate weighs approx 1250kg and get 27 MPG, when towing we try and stick to Motorways, Dual Carriageways and good A roads if possible. I don't think that's too bad. I used to tow a slightly lighter van with a 2.5tdi 150ps Audi A4 Avant, that averaged 39mpg in mixed driving and also did 27mpg towing. From these figures I reckon towing fuel consumption is about 70% of non towing consumption. That of course can change depending on how you drive and other things like roof racks,bike carriers on the roof etc.
