Grease vs. Lubricant: What to Use and When in DIY Projects

When it comes to keeping things running smoothly, grease and lubricants are two essentials in any DIYer’s toolkit. But despite being used interchangeably by many, they serve different functions and work best in specific scenarios. 
 
In this guide, we break down the difference between grease and lubricant, when to use each one, and how to apply them properly for everything from bike maintenance to power tools. 

Grease vs. Lubricant: What’s the Difference?   

**Lubricants** are usually oils or sprays that reduce friction between moving parts. They’re thin, fast-acting, and perfect for tight spaces or frequent motion. 

**Grease** is a thicker substance made by combining oil with a soap or thickening agent. It stays in place longer and works better for parts exposed to high pressure, moisture, or load. 


When to Use Lubricants 

  • **Door hinges and locks**: Prevent squeaking and sticking
  • **Power tools**: Keep motors and moving parts friction-free
  • **Garage doors**: Lubricate rollers, springs, and tracks
  • **Bikes and lawn equipment**: Use on chains, gears, and cables 


When to Use Grease 

  • **Automotive repairs**: Apply to suspension parts, bearings, and brake caliper pins
  • **Heavy machinery**: Grease joints and fittings for smooth movement under pressure
  • **Outdoor equipment**: Grease helps resist washout from rain or heat 

Application Tips 

  • Always clean surfaces before applying grease or oil
  • For precision, use applicator nozzles or grease guns
  • Don’t overapply—excess grease attracts dust and debris
  • Wipe off old lubricant before refreshing
  • Store products in sealed containers to avoid contamination 

Grease Types for Home Use 

  • **Lithium grease**: Ideal for metal-on-metal contact (hinges, bearings)
  • **Silicone grease**: Safe on plastic and rubber (weather stripping, battery terminals)
  • **White grease**: Good for home tools and clean applications (garage doors, slides) 

Bonus Tip: Keep a Lubrication Log 

For tools, bikes, or garage door systems that require occasional lubrication, keep a simple log noting when each item was last serviced. This helps avoid over-lubrication or neglect and ensures your most-used gear stays in top shape. Label your grease tubes and oil bottles by type to avoid mix-ups. 


Storage and Safety Considerations 

Store greases and lubricants in a cool, dry cabinet away from open flames or direct sunlight. Keep caps sealed tight and avoid cross-contaminating products. Always wear disposable gloves when handling grease and dispose of used rags or paper towels in a metal bin to prevent spontaneous combustion. 


Conclusion 

Knowing when to use grease versus lubricant can extend the life of your equipment and improve the performance of everything from garage doors to garden tools. OneSource Supply Co. offers a wide selection of sprays, oils, and greases for every kind of DIY application.
