Rotella T-6 vs T-4
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!
