I would not run a filtered only reclaim oil. I won't trust it enough even if it is from my own car due to not having enough way to check for it before putting it in another car or back to itself after top off with additives etc. The dissolved "salt" from depleting additive, the proportion of base oil ratios, etc are not something I can check for. It is easier for the large blender to do those instead in large scale.
I have no problem running re-refine oil, but I think due to public opinion they didn't sell well in the market. So now they probably only goes to government fleet or they just blend it into new oil without telling anyone, which is fine by me since they are just molecules anyways, regardless of which source after distillation.
The oil from your car is already filtered
Letting the oil settle for a month clears out virtually all the particles not caught by the oil filter. There's a nice layer of dirt in the bottom after a month.
I rarely find a few particles bigger than 1 to 2 microns in 4,000 mile oil running through an oversized 10,000 mile old oil filter.
Only time I was able to clog up an oil filter was when I ran a stock sized royalpurple oil filter for 9,400mi on my wife's car. Shhhhh dont tell her.... I had dozens of particles visible under my microscope at any moment, virtually all were less than 3 microns.
It appears particles bigger than about 5 microns are quickly ground up by your engine, even in small engines with no oil filter to the 1 to 2 micron size range.
Yeah that's why the main uses for reclaim oil are flushes, bar and chain oil, all applications where the additives don't matter.
Only time I put reclaim oil in a vehicle is to flush out gear oil milk shake or sludge metal flake from from a neglected diff, drive around the block and dump and refill till the milkshake or metal flakes clear out.
If I got ahold a terribly neglected car I might put reclaim oil in its engine if:
I'm low on fresh oil.
Have reason to suspect the car is a lost cause.
Has suspected head gasket leak.
Has a situation causing bad fuel dilution.
Is burning oil really bad.
Ect.
Saftykleen is supposed to be recycled oil and its one of the toughest oils around.
It's almost like running the oil in an engine breaks down the weaker bonded molecules first, you recycle it, run it again and a lot of those first to fail molecules just aren't there after its recycled.
