On our farm, used motor oil was applied to shiny plow shares to prevent rust. We also poured it on the dirt lanes to control dust. Many uses that to this day, I see no harm in? Paul www.severngaspumps.com
We also used to pour a little bit of oil on areas of standing water in the spring and summer. It does a nice job of smothering mosquito larvae and reducing mosquito population.
On the farm dad would have me pour the used motor oil over the tops of the fence posts. That was over 50 years ago and some of those posts are still solid in the ground. Tom.
