Tony, I have a 2009 2.5TD (Just edited my signature). It is due its 10k service not the 100k, bought it new in March. I have a mechanic mate & he is a little down on the dealer servicing that's why I started this thread to get a more "General" feel.
Re. the oil used by our local dealer. They use Shell Helix & are adamant, as long as the oil used is a C3 low ash with a viscosity between 5W-40 (As per the owner's manual 9-4) Nissan will honour any claims.
I have more & more doubts about the Geelong dealer. I mentioned the concern you raised about the standard tow bar using level riders & they bought out a Nissan memo warning not to use them because of problems with the Pathfinder. I asked how the Pathfinder, with its totally different rear end would make it a problem for the leaf sprung D40. Their answer, "I don't know!"
I have just got off the phone to Pedders & they know of the problem with both the Pathfinder & X Trail using standard Nissan tow bars, but have not heard of any problems with the Navara D40.
I am not that impressed.
Phil
