There's a lot of discussion on this forum of specs and qualifications for specific applications, but I have a more general question. Are newer oil formulations and their additive packages actually better at protecting an engine from wear, or are they mainly driven by manufacturer requirements based on emissions and the sort? I see talks of boron and titanium and other additives, and certain companies moving away from things like Moly and ZDDP. I know there are pros and cons to everything, but I'm just interested in this kind of discussion, which requires a bit more science than label reading . Maybe I'm just a nerd.
Yes, it is applicable to my vehicles if you're curious. I have an RB25 swapped S13 and another S13 with a built SR20DET about to go in. I have no need for emissions related requirements, but these are street cars that see the track, so long drain intervals would be nice if I can get away with them. They do have proper PCV setups, and will be run on a both E85 or pump gas depending on what's available. At the end of the day I'll probably be doing a lot of testing on a variety of oils, but it in the mean time I'd like to narrow down my list if possible.
I've attached a spreadsheet I've made for kicks and gigs.
