Good morning. This is my first post. I read BITOG a year or 2 ago & have been stuck on learning more since. So, thank you in advance to your responses. I will definitely heed them.
My truck is stated above. It currently has 111,800 miles on her. I bought her in February 2010. Below are my 1st & 2nd readings.
Oil is Delvac 15w-40 for both UOAs; service is Blackstone. (edited by moderator 1-6-12 for oil information update).
MI/HR on Oil: 10,281, 6,350
MI/HR on Unit: 102,363, 98,432
Sample Date: 03/18/11, 12/30/10

SUS Viscosity @ 210°F: 74, 74.2
cSt Viscosity @ 100°C: 13.99, 14.04

Fuel %: Antifreeze %: 0, 0
Water %: 0, 0
Insolubles %: .2, .2
TBN: 7.6, 8.8
From what I've read so far, I think these numbers are good. The oil since I have purchased the truck has been Mobil Delvac 1300 15/40. I like the idea of the T6 5/40 due to the cold weather we get up here in New England. I even ran it in Vegas when I was out there when I had my old 2002 7.3 PS with no issues. My reason for wanting to switch is the pour point. I think. I'm not sold on synthetic after all I've read. I'm now also starting to see T5 10/30. Is it safe in these 6.6's? I want to get the oil up and moving in the engine as soon as possible, but don't want it too thin. Should I go 5/40 or 10/30?
My apologies for the formatting.
