Probably.......for some at least, the psychological-factor value is, perhaps, the biggest return for dollars spent. For those who are ever-minful of mechanical tolerances/friction/heat/wear, preservation of rare saws/components, and....have spent time on the 'bobistheoilguy' forum, etc., hashing out the minutiae of base stocks, additives, zinc/ZDDP, flash point, shear, etc. & etc.....knowing that one has a top-quality lubricant ANYWHERE where there is friction/heat can make running any machine more pleasant...
In an imperfect world, anywhere where one can make things....smoother, it's nice to do so
**Oh and....watch out on the used motor oil: There's schtuff in there that is kinda toxic, such that one wouldn't want to even have any prolonged skin contact. I sure wouldn't want to be slingin' it off a bar, and...... vaporizing it not too far from the ol' air intake [NOSE...not the saw ! ]
