What are the benefits of using motor oil as a wood preservative?

Using motor oil as a wood preservative can provide benefits such as protecting the wood from moisture, preventing rot and decay, and increasing its lifespan. Additionally, motor oil can act as a barrier against insects and fungi, helping to maintain the structural integrity of the wood over time. However, it is important to note that using motor oil as a wood preservative may have environmental and health risks, so caution should be exercised when using this method.
