Either one will be OK. It's personal preference IMO. The 5 means the oil acts like 5 weight oil when cold so both will help with cold weather starting. I llike the 5w40. Just
Be sure it's diesel rated oil.

so I've been shopping around. and it seems that is I'm going to switch to syn. I should also put in a bypass filter while I'm at it..I've been thinking of going with the Amsoil filter and there 5w-40oil anyone heard any theing bad about this set up? any other recomendations ? I looked at the oil gaurd but it is slightly more exspensive and since I was thinking of going amsoil the whole way I thought I would use theirs. thanks for any thoughts J

Go with a bypass system. All are good. Your oil will be cleaner and last longer.
You will not regret the change this winter.
I have noticed that the winter startup is better with the 5/30 than 5/40.
As the oil is used and ages it beats itself thick. In other words a 30 can become a 40.
On a note the 40wt nets a very slight advantage in mpg.

Yep. Normally the 30wt would do better windage wise in the crankcase ect. The PSD also uses the oil to drive the injection system. A scanner has shown that the 40wt makes a slight bit more pressure across the RPM band than the 30wt. The higher pressure helps with timing and atomization of the fuel.
I use the amsoil bypass. (stand alone unit).
Dont like to name brands anymore when all are good. To many BS oil wars.
