Used oil has a lot of uses there GH. Bar/chain oil for one, fuel, spot lubrication… to boot, most everything has lead free bearings now too, so it’s not a leaded haz waste for most part…
good post. I will probably never buy bar oil again ever.
Tis a watermelons conundrum.
Sooner or later, after recycling/reuse, refined petroleum products are burned for BTU recovery, emitting CO2.
Which is worse; returning the oil to its source (Gaia) or harming Gaia with more CO2?
