Rotella T-6 vs T-4

[Belize]

I have been using Shell Rotella T-6 here in Belize in my 2006 E350 6.0. The Shell dealer says they are no longer bringing it in, only T-4 which is blended. Is there a problem switching to T-4? If so, what other brand/type synthetic should I be looking for. I haven't started looking for anything yet, so a couple of suggestions would be great. Thanks!

I very seriously doubt it would be a problem. I run both in heavy trucks, T6 lately but it is thin. Still, it is on the recommended list for my rig so I use it.

Do you have farm/ranch stores down there? That's where I get it, 2.5 gallons for $50ish.

I have no idea about what might be acceptable for the 6.0 but I don't have a good feeling based on it's reputation.

Howbout going this route?
