After the results I got from an earlier VOA on this oil noted in an earlier thread https://bobistheoilguy.com/forums/threads/voa-rotella-t-syn-5w-40-ci-4-sh.80619/ I sent another sample to Blackstone.
It's RTS 5-40, CI-4+/SL rated.
RON: This 5W/40 oil from Shell looks perfect in our analysis. The TBN was 12.5, about as high as you see virgin oils go and it would read the same for their petroleum-based 15W/40. This is the synthetic form. We rarely see a problem with it though we do often see problems with other types of synthetics run in diesel engines. (my emphasis - wonder what that means?) For the purposes of this analysis though, we found no problems in this sample of unused oil.

Based on the unusual numbers in that earlier VOA, which about caused an infarction based on the zinc/phosphorous numbers, and the fact that we have it in a pile of expensive equipment, all I can figure is someone must have been in the garage playing with my oil jugs. That, or I worry too much.
