If you own a treadmill, you know regular care keeps it running smoothly. A common question is what oil to use on treadmill belts, and using the right one is crucial for its lifespan.
What Oil To Use On Treadmill
Not just any oil will do. Treadmills require a specific type of lubricant designed for their unique mechanics. Using the wrong product can damage the belt and deck, leading to costly repairs.
The correct choice is 100% silicone-based lubricant. This is not a standard oil like WD-40 or household 3-in-1 oil. Those can actually degrade the belt material.
Why Silicone Lubricant is the Only Choice
Silicone lubricant has special properties perfect for treadmills. It doesn’t attract dust and dirt like petroleum-based oils. This keeps your machine cleaner.
It also won’t break down the composite materials of the walking belt. This preserves the belt’s integrity and prevents slipping. Here’s what to look for when you shop:
- 100% Silicone: The label should clearly state this.
- Treadmill-Specific: Many brands sell lubricants marketed for fitness equipment.
- Non-Flammable & Odorless: For safety and a pleasant workout environment.
What to Avoid: Dangerous Substitutes
It’s tempting to use what’s already in your garage. Resist that urge. Common wrong choices include:
- WD-40: This is a penetrant and water displacer, not a lubricant. It dries out and leaves residue.
- Household Oil (3-in-1): These are often petroleum-based. They attract grime and can cause belt deterioration.
- Spray Silicone with Additives: Some spray silicones have petroleum propellants. Stick with pure, liquid silicone.
- Cooking Oil or Grease: Absolutely not. They will go rancid, become sticky, and ruin your treadmill.
How Often Should You Lubricate Your Treadmill?
There’s no single answer. It depends on how much you use it. A good general rule is every 3 months or every 130 miles. Check your owner’s manual for the manufacturer’s recommendation.
Signs your treadmill needs oil include:
- The belt feels sticky or hesitates when you start walking.
- You hear a squeaking or rubbing noise from the deck area.
- You feel increased friction underfoot.
- The motor seems to be working harder than usual.
Step-by-Step Guide to Lubricating Your Treadmill
Gather your supplies: a can of 100% silicone lubricant, a clean cloth, and a screwdriver (maybe). Always unplug the treadmill before you start.
Step 1: Locate the Lubrication Points
Most modern treadmills are lubricated from the top. You lift the belt and apply oil between the belt and the deck. Some older models require access from underneath.
Step 2: Center the Belt
Make sure the running belt is centered on the deck. There should be an even gap on both sides. You can adjust it with the rear roller adjustment bolts if needed.
Step 3: Lift the Belt and Apply Oil
Gently lift the edge of the walking belt. Apply a thin, 3-inch wide line of silicone lubricant down the center of the deck. Do not overapply. A little goes a long way.
Repeat this on the other side, lifting the belt from the opposite edge. You want two lines of lubricant under the belt.
Step 4: Spread the Lubricant
Plug the treadmill back in. Set it to a slow speed, like 1 or 2 mph. Walk on it for 2-3 minutes. This helps spread the silicone evenly across the entire deck surface.
Step 5: Wipe Away Excess
After spreading, unplug the machine again. Use a clean cloth to wipe any excess lubricant from the edges of the belt and deck. This prevents dirt buildup.
Troubleshooting Common Lubrication Problems
Even with the right oil, issues can pop up. Here’s how to handle them.
Problem: The Belt Still Squeaks After Oiling
This could mean the belt is to tight. Check the tension. You should be able to lift the belt about 2-3 inches off the deck at the midpoint. Also, ensure the belt is centered properly.
Problem: The Belt Slipping or Dragging
Slipping often means not enough lubrication or a worn belt. Dragging can mean to much lubrication or a belt that’s to tight. Wipe away excess oil and re-check tension.
Problem: You Used the Wrong Oil
If you accidentally used a petroleum oil, you need to clean it off. You’ll likely need a treadmill belt cleaner kit to degrease the belt and deck thoroughly. Then apply the correct silicone lubricant.
Maintaining Your Treadmill Beyond Lubrication
Oiling is just one part of care. For a long-lasting machine, follow these tips:
- Clean Regularly: Wipe down the console, handrails, and belt surface after workouts to remove sweat and dust.
- Check for Wear: Inspect the belt and deck periodically for signs of excessive wear or cracking.
- Keep it Level: Ensure your treadmill is on a level floor to prevent uneven wear on the motor and belt.
- Vacuum Underneath: Dust and debris under the machine can affect it’s motor and electronics.
FAQ: Your Treadmill Oil Questions Answered
Can I use treadmill lubricant on other exercise equipment?
It depends. Silicone lubricant is sometimes good for elliptical tracks or slide rails. Always check the other equipment’s manual first.
How do I know if my treadmill is self-lubricating?
Many newer models have a “lube-free” or self-lubricating deck. Your owner’s manual will confirm this. You should not add oil to these decks unless the manufacturer instructs you to.
What is the best brand of treadmill lubricant?
Most 100% silicone lubricants from fitness brands (like Spot-On, Triflow, or manufacturer-specific kits) work great. The “best” one is often the one recommended by your treadmill’s maker.
Is it bad to overlubricate a treadmill?
Yes. Too much oil can cause the belt to slip and attract a lot of dirt. It can also create a mess. Always apply conservatively.
Using the correct oil protects your investment and ensures quite, efficient workouts. Remember, the answer to what oil to use on treadmill is always a pure, 100% silicone formula. Stick with that, follow a simple maintenance schedule, and you’ll enjoy many miles on your machine.
