Hi, @High Performance Lubricants.
Do you have any experience or reservations about running the mid-SAPs flavors beyond the usual 10-12k mi computer calculated OCIs in Euro applications calling for full-SAPs in the US?
Context: Recently analyzed a top shelf full-SAPs LL01/229.51/A40 in "spirited" all highway conditions for 10.5k mi and 11 months, and was somewhat surprised to find TBN was about to cross over the virgin TAN. Aware that real world TBN retention can vary wildly even if base number starts low/high in a particular oil. Obviously sampling is still important to gauge long term suitability for an application.
Thanks in advance!
