Ours is a Paj diesel and rang the Peter Kittle motor company. Done by a contractor by the look of it, round the back of the dealer. I think he does all the dealers in the block (Mitsi, Holden, Nissan, Toyota, Honda).

They are also in Tennant Creek
No issues with them, but it was just an oil change plus filter.
