I have this new to me 300. I notice that the oil pressure raises slowly but goes 2/3 to 3/4 the way over on gauge after about 30-45 seconds. I also notice that when engine is shut off, it takes 15 seconds for the oil pressure to go back down. Is this a line and gauge issue? Be cause the engine runs quiet and I don't belive it is being shorted oil.
I changed the oil upon delivery and it was real black. The new oil has stayed clean after several hours of running.
