Tradition is to save it and use it as a wood oil so the wood will not decay after some time on the rain. Absorbs really good, doesn’t stink or stick…
Yeah, but there’s stuff for that that doesn’t give you eleven different cancers.
There’s a lot of plant based oils you can use, without additives, that give excellent weather protection. Choice of wood is also a huge factor.
Tbh I’d rather replace my fence every five years than cake it in used motor oil.
Was about to mention that. But you forget to mention the half-and-half mix of oil and diesel to prevent wood rot and insects.
If you got a very thick oil, yeah a mix of diesel and oil is good so it would lose on viscosity and would be easier to get it on and into the wood. But today’s engine oils are not really that thick and can be used without any mixing with oil of lesser viscosity such as diesel. Nowadays you can find those very thick oils mostly in tanks (military vehicles) and big machines not your everyday family car.
I mentioned that in particular because the house I’m living has beams that were treated with that mix when it was built, back in the 40’s. And the neither rots nor gets infested. But the added fire damage is there.
So you’re saying I have to take up an entirely new hobby I have no interest in just to dispose of my used engine oil?
