Only had the D3 TDV6 a 6 months but getting around 9.2 on the highway and 11.5 around town.
Towing the van around 14.5 on the highway.
Did find over Christmas when towing was using 16 +, as found a turbo boost hose leak.
Had all the bells and whistles going off & had to reset the computer to get home, along with heaps of black smoke out the back.
$500.00 later all good.
Cant believe how much power the Diesel throws out and fantastic when overtaking.
