Understanding the “Motor Oil to Lube Gun” Concept: Why It Works (and When It Doesn’t)
The idea of putting motor oil into a lube gun might seem unconventional at first, but it’s a practice rooted in sound lubrication principles. Understanding when and why to make this switch is crucial for successful and effective maintenance.
The Science Behind Lubrication: Oil vs. Grease
Both oil and grease serve the fundamental purpose of reducing friction and wear between moving parts. The key difference lies in their composition and viscosity.
Motor oil is a liquid lubricant, typically formulated with a base oil and various additives. Its fluidity allows it to penetrate tight spaces and dissipate heat efficiently. It provides excellent film strength under pressure.
Grease is essentially motor oil thickened with a soap base or other gelling agent. This semi-solid consistency allows it to stay in place longer, resist washout, and provide a protective barrier against contaminants, making it ideal for applications with infrequent lubrication or exposed environments.
When Motor Oil Shines: Specific Applications
The benefits of motor oil to lube gun applications are numerous, particularly for components that require frequent, light lubrication or those with tight clearances.
- Penetration: Motor oil’s lower viscosity allows it to penetrate small gaps and intricate mechanisms where thick grease might struggle to reach.
- Cleaning Action: As it flows, motor oil can help flush out contaminants and old, degraded lubricant, especially beneficial for chains and cables.
- Heat Dissipation: The liquid nature of oil helps carry heat away from friction points more effectively than static grease.
- Accessibility: If you already have a supply of motor oil for your engine, using it for other lubrication tasks can be convenient and cost-effective.
Examples include door hinges, throttle cables, shift linkages, bicycle chains, small engine components, and certain unsealed agricultural equipment pivot points.
When to Stick with Grease: Critical Considerations
While versatile, using motor oil in a lube gun isn’t a universal solution. There are critical situations where traditional grease remains the superior choice.
- High-Load, Low-Speed Bearings: Components under extreme pressure or shock loads, such as wheel bearings, require the robust film strength and staying power of grease.
- Exposed Environments: Parts constantly exposed to water, dirt, or dust benefit from grease’s ability to create a sealed barrier and resist washout.
- Infrequent Lubrication: For components that are difficult to access or only lubricated once a year, grease provides longer-lasting protection.
- Sealed Fittings: Many modern automotive components, like ball joints and tie rods, are sealed for life and not designed to be greased or oiled. Attempting to force lubricant into them can cause damage.
Always consult your vehicle’s service manual or component manufacturer’s recommendations. If a component specifically calls for grease, stick to grease.
