Opinion based on is it rated the as being the right oil? Or would we want to run that oil as a preference?

What about Rotella T6. I believe it is as good as Amsoil.

Great oil, on the expensive side for my tastes, probably overkill unless you extend your OCI interval (or have $$$ to burn).

Good oil but probably overkill unless your stretching the OCI or arctic conditions with no block beater. I have Valvoline Premium Blue 15w40 in my 525 horse ISX. 10k OCI.

10k OCI on an ISX -- why?

Hauling milk. Lots of farm pickups and stop and go driving. Some guys have a 15 miles drive to the plant from their last farm. I have a 95 miles drive...

Amsoil makes very good products.

Whether this is a good choice for the engine is dependent upon a host of many other things, so far not revealed by the OP.

The the correct answer is "maybe so, maybe not" ...

If "normal" use and OCIs are planned, then this is a waste of money. If abnormal use and/or greatly extended OCIs are planned, then it may be beneficial.

More info = more detailed answers.

The "best" answer will come from UOAs; why guess when you can know?
