I'm new to these but I brought a new one home yesterday and it seems that the oil pressure seems to be reading on the low side. Like I said, I'm new to this vehicle so I can't tell what is "normal" for it. But I seem to read that this may be an ongoing issue for this engine and some models including the Land Cruiser. Does anyone have thoughts about this? What might be normal or what I should expect or do about this, if anything.
