Grade of Oil
I've got the GC Ltd, 5.2L 1997, if I drive for awhile say an hour the oil pressure gauge needle drops to nothing, putting it in neutral brings the needle back up or accelerating. Does this mean that the sending unit is packing it in or is the oil too thin, I use Castrol High Mileage GTX 5w30
