I'm sure there are probably proprietary secret blends and such but i'm also assuming alot of information must be public, about what the minimum suggested additives and amounts must be in a given oil blend for a given level of performance. Heck i'm even curious about the history of oil since i'm sure there was no additives originally and at some point they researched and discovered adding something improved something else...
I read articles on vegetable based oils for lubrication, which got me thinking whether it would be possible to "brew your own" by buying some bulk source of the same stuff used in your Havoline and adding it to your bottle of thousand island dressing. :^)
I'm saying that with a smirk because it's a little toungue in cheek... i'm not actually planning on doing literally that but I AM curious about the chemistry of what is added, and why/what it does, and how they decided a certain amount was good, vs what happens if you have too much. I was curious whether independant sources were available for those chemicals, or at least the most important things, in part because i'm wondering if they could be added to "old but clean" existing oil. All the guys who run 25,000 miles or something on their super-bypass-filtered oil I would assume would be running out of the detergents and other such in the oil, which made me wonder if you could simply blend some back in...
I've no idea whether this is something where were being ripped off by the oil companies, or where it's more expensive to DIY than just replace the oil because competition has made the costs marginal.
I'm even curious whether there would be any way to home reprocess oil to make it more suited to longer oil change intervals. As a random example if I had some ring blowby, and some fuel was getting into the oil, is there any possible way to ever get that back out of there (filtering, centrifuging, settling) or is the oil chemistry ruined forever. This is less a fully serious question (in terms of people telling me to not waste my time since I doubt I will) and more an honest curiosity about lubrication oil chemistry and how things change in use.
