I would check that- Rotella has changed the last few years to keep up with the advances in diesel engine technology, one of them being the introduction of catalytic converters in some new trucks with the subsequent reduction of ZDDP in their oil formulations.  There have been other changes as well.

That's why they're up to T5 (or 6) now. T2 straight weight is still the spec it originally came in. It's actually specified for stationary diesel power plants, not vehicles. 

 I verified the the zinc level with the shell distributor before I decided to use it.
