If you’re wondering what lubricant can i use on my treadmill, you’re asking the right question. Using the correct lube is essential for keeping your machine quiet, smooth, and long-lasting. This guide will walk you through everything you need to know, from choosing the right product to applying it correctly.
What Lubricant Can I Use On My Treadmill
Not all lubricants are created equal, and using the wrong one can damage your belt and deck. The specific type you need depends on your treadmill’s model and manufacturer instructions.
Approved Treadmill Lubricant Types
Most modern treadmills require a 100% silicone-based lubricant. This is the industry standard for a reason. Silicone lube won’t break down the belt material, provides excellent slip resistance, and doesn’t attract dust and dirt like petroleum-based products can.
You will typically find it sold as a treadmill-specific silicone lubricant. It often comes in a small bottle with an applicator tip for easy use.
What to Avoid
Never use these products on your treadmill belt and deck:
- WD-40 or similar penetrating oils (it’s a solvent, not a lubricant)
- Household oils like vegetable or 3-in-1 oil
- Petroleum-based greases or sprays
- Automotive lubricants
- Any wax-based products unless explicitly recommended by your manual
These can degrade the belt, cause slippage, and create a gummy, dirty mess that’s hard to clean.
How to Find Your Treadmill’s Requirements
The absolute best source of information is your owner’s manual. Check the maintenance section; it will specify the type and sometimes even the brand of lubricant to use.
If you’ve lost the manual, don’t worry. You can usually find a digital copy online by searching your treadmill’s make and model number. The model number is often on a sticker near the motor hood or on the frame by the power cord.
Step-by-Step Lubrication Guide
Once you have the right silicone lubricant, follow these steps. You’ll need a clean cloth, maybe a friend to help, and about 20 minutes.
Step 1: Prepare the Treadmill
Unplug the treadmill from the wall outlet for safety. This is a critical step to prevent any accidental startups. Position the belt so you can access its entire surface under the hood.
Step 2: Lift and Secure the Belt
You need to create a gap between the belt and the deck. Stand at the side of the treadmill, grip the belt from underneath, and lift it up. You should be able to slide your hand between the belt and the deck. If it’s very tight, you may need to slightly loosen the rear roller adjustment bolts (consult your manual for this).
Step 3: Apply the Lubricant
With the belt lifted, apply a thin bead of silicone lubricant onto the deck. Don’t overdo it. A common pattern is to make an “S” shape or two long stripes along the deck, about 2-3 inches from each edge. You only need to cover the center two-thirds of the deck where your feet land.
A little goes a long way. Using to much can cause the belt to slip.
Step 4: Spread the Lubricant
Lower the belt. Now, you’ll help spread the lubricant evenly. Turn the treadmill on to a very slow speed, like 1 or 2 mph. Hold onto the handrails for safety. Let the belt move for about 30 seconds to a minute. This allows the lube to distribute under the entire belt surface.
Then, turn it off and unplug it again. Walk on the belt manually, shifting your weight from side to side, to help spread it further.
Step 5: Check Belt Tension and Alignment
After lubricating, it’s a good time to check your belt tension and alignment. The belt should not feel loose or slip when you walk on it. It should be centered on the deck. If it’s off, you may need to make minor adjustments using the rear roller bolts.
How Often Should You Lubricate?
There’s no one-size-fits-all answer. It depends on how frequently you use your treadmill. A general rule is to lubricate every three months or every 130 miles of use, whichever comes first.
Listen to your treadmill. If you hear a squeaking sound from the belt area, or if the belt feels like it’s dragging or sticking, it’s probably time for lubrication. Also, if you notice you have to increase the incline or speed to feel the same resistance, that can be a sign of increased friction.
Common Mistakes to Avoid
- Over-lubricating: This is the most common error. Excess lube can cause belt slippage and attract debris.
- Lubricating the top of the belt: You apply lube to the deck, not the belt itself.
- Using the wrong product: We can’t stress this enough—only use 100% silicone lubricant made for treadmills.
- Forgetting to clean first: If the deck is dirty, wipe it down with a damp cloth and let it dry completely before applying new lube.
- Ignoring the manual: Your manufacturer knows best what your specific model needs.
Cleaning Before Lubrication
It’s a good practice to clean the deck before applying fresh lubricant. Unplug the machine and lift the belt. Wipe the deck with a cloth dampened with a mild soap and water solution. Avoid harsh chemicals. Make sure the deck is completely dry before you apply the new silicone lubricant, as water can interfere with it.
Troubleshooting Post-Lubrication Issues
Belt is Slipping
If the belt slips underfoot after lubrication, you likely used to much. You’ll need to remove the excess. Unplug the treadmill, lift the belt, and wipe the deck with a clean, dry cloth to absorb the extra lube. You might need to run the belt slowly while pressing a clean towel against the deck from underneath to soak it up.
Treadmill is Still Noisy
If you’ve lubricated but still hear noises, the issue might not be the belt. Squeaks or grinding could come from the motor, rollers, or bearings. Belt noise is usually a low, rubbing sound. Other mechanical noises need a different inspection.
FAQ Section
Can I use silicone spray from the hardware store?
Maybe, but be very careful. Some silicone sprays contain additives or petroleum distillates that can harm the belt. It’s safer and more reliable to use a product labeled specifically for treadmill use.
How do I know if my treadmill is self-lubricating?
Some high-end models have a self-lubricating system. Your owner’s manual will clearly state this. If it is self-lubricating, you typically add lubricant to a reservoir, not directly to the deck. Never assume it’s self-lubricating without checking.
What happens if I never lubricate my treadmill?
Without lubrication, friction between the belt and deck increases dramatically. This causes the motor to work harder, leading to premature wear on the belt, deck, and motor. It can result in costly repairs or even the need for a full replacement much sooner than expected.
Can I use treadmill lubricant on other exercise equipment?
100% silicone lubricant can be safe for some other equipment, like elliptical tracks or slide boards, but always check those manuals first. It is not suitable for bike chains or weight machine joints, which need different types of grease.
My manual says to use a paraffin-based lubricant. Is that okay?
Yes. Some older treadmill models or specific brands (like some ProForm or NordicTrack models) recommend a paraffin wax. Always follow your manual’s instructions. If it says paraffin, use that. If it says silicone, use silicone. Don’t interchange them.
Final Tips for Treadmill Care
Regular lubrication is just one part of treadmill maintenance. Remember to also vacuum underneath and around the machine to prevent dust from getting inside. Wipe down the console and handrails after each use. Check the power cord periodically for any damage.
By taking these simple steps, you ensure your treadmill runs smoothly for years, giving you a reliable workout whenever you need it. Taking care of your equipment means it will take care of you.
