Can mineral oil be used to lubricate tools or engines?
The answer is yes—but with some limitations and considerations.
When Is Mineral Oil a Good Lubricant?
Mineral oil can be used as a light-duty lubricant for hand tools, hinges, sewing machines, kitchen appliances, and other small mechanical parts. It works well in these scenarios because of its smooth texture, non-reactive nature, and resistance to evaporation or gumming up.
For example, you can use mineral oil to:
- Lubricate garden shears or pliers
- Prevent rust on metal tools
- Maintain the smooth motion of door hinges or drawer tracks
- Lubricate bearings in fans or sewing machines
In these low-heat, low-pressure environments, mineral oil provides excellent lubrication without attracting too much dust or debris.
What About Engines?
When it comes to internal combustion engines (like car or motorcycle engines), mineral oil is not the best option in its raw form. While early engine oils were based on untreated mineral oil, modern engines require highly engineered motor oils that include additives to handle extreme temperatures, high pressure, corrosion, and fuel contaminants.
Plain mineral oil lacks these advanced additives and can break down under high heat, leading to poor lubrication, sludge buildup, and potential engine damage over time. So while technically it could be used, it is not recommended for high-performance or long-term use in engines.
How Does Mineral Oil Compare to Other Substances?
In the world of lubrication and protection, mineral oil is often compared with products like petroleum jelly, waxes, and even cable gels.
- Petroleum jelly can be used on tools too, particularly for corrosion prevention, but it's thicker and better suited for surface protection than moving parts.
- Waxes (like paraffin or beeswax) are excellent for coating and sealing but aren’t effective as lubricants because they harden over time.
- Cable gels, used primarily in fiber optic and power cables, offer water-blocking and insulating properties, but are designed for stationary, enclosed environments—not mechanical movement.
Therefore, mineral oil strikes a balance between lubrication and ease of application, especially when you need a cleaner, non-sticky alternative to heavier greases.
Conclusion
Mineral oil is an effective lubricant for tools and small machinery, offering smooth performance and rust prevention. However, it should not be used in engines, where high-performance motor oils with additives are necessary. For general maintenance and lubrication of household or workshop items, mineral oil is a safe, clean, and affordable choice.
