T6 rotella 5-40 is the best choice for 6.0 liter.

Why 10w30?

IMO Ams oil is a far better choice than Rottela

I second the choice for Amsoil, either the 5-30 Series 3000 or their 15-40 Marine oil. I have been using their products for over 20 years and have never been let down. Their products always work better than advertised.

You want 40 weight oil in your 6.0 and most diesels. 5w40 helps on cold starts because it is a 5 weight when cold and 40 weight when warm. You have to be in extreme cold before you drop to a 30 weight oil, -30* and colder.

If you change your oil every 5k, Amsoil is pointless.

I have the BPD oil cooler and relocated oil filter. Is the T6 rotella 5-40 still recommended? I also have the Napa Gold oil filter 1832. Thx!,

I cant imagine an oil cooler changing a requirement of viscosity. Rotella T6 is the most cost effective synthetic out there. $21/gallon at Wally World.

I've been using 10w-30 for a few years with excellent UOA results.

For as long as I own a 6.0 its the only viscosity lube I'll use.
