HI Guys... yep bee AWOL again.... Just saw this post from my old mate "rusty".. so thought I would add my recent experience, fuel wise.
Did the Christmas round trip Richmond (NSW), to Ballina via New England Hwy.. run around Ballina and environs... and then Ballina to Richmond via the Pacific Hwy..
Overall average 47 MPG and the trip back was 52 MPG. Used Aircon where required and cruise control where safe to do so.... sat on the obligatory +5 KPH over the limit...
Elle B then had 130K..... 2009 CW Auto Diesel. (Been to Melbourne and back since then... haven't done the figures

)
Happy with that !!!

Now ( 143K) ..I need new front discs and pads... but will post a new one for any of the latest tips there.
