Best oil and lubricant?

[windmill86]

I am going to do a full tune up on my truck this weekend and am new to the diesel game. I would like to get others opinions on the best oils and lubricants.Any and all input is appreciated. I plan on doing the oil, coolant, auto tranny and rear diff along with coolant bypass mod filter, oil bypass mod filter, air filter, trans filter and possibly rear diff cover! Any suggestions on types of oil and lube and also filters and diff cover would be awesome!
