A number of mazda 6 diesels are coming thru the door with oil pressure problems.
This can usually be traced back to a blocked oil pick up.
We recommend removal of the engine oil pan & clean up of the oil pick up every 100,000km.
Dont risk it.
Have your oil changed regularly & oil pick up cleaned out at around the 100,000km mark, it will save you heartache & a HUGE bill.
