Treadmill Lubricant: 7 Best Silicone Lubes for Belts and Walking Pads

A treadmill lubricant sits between the underside of the belt and the deck. It cuts friction, so the motor draws less effort, the belt runs cooler and the deck wears more slowly. KingSmith's WalkingPad manual calls for silicone oil, LifeSpan and UREVO call for 100% silicone, and SOLE tells owners to use only its own silicone-based lube. Below we compare seven silicone treadmill belt lubricants by bottle size, applicator and the machines they suit, then explain lubricant types, what makers rule out and how far a bottle goes. For the steps and the schedule, see our guide on how to lubricate a walking pad.

The 7 best treadmill lubricants, in detail

1. Noosa Life Treadmill Belt Lubricant: best for walking pads

Why we picked it: Walking pads sit low and their belts are narrow, so the hard part is getting oil to the middle of the deck without lifting the frame far. Noosa Life pairs 100% silicone oil with a 10-inch applicator tube, which is long enough to reach the center of a typical 16-inch walking pad belt from each side. The Amazon listing names walking pads and folding treadmills in its compatibility claims, and Garage Gym Reviews and BarBend both describe it as a 100% silicone, USA-made lube with no propellant.

Key specs:

• Type: 100% silicone oil, propellant-free
• Size: 4 oz (Garage Gym Reviews and BarBend)
• Applicator: 10-inch tube
• Made in: USA (seller claim)
• Applications per bottle: about four on a full-size treadmill (BarBend estimate)

Who should skip it: owners of SOLE or Horizon treadmills who want to follow the maker's own lube rule to the letter, and anyone with a 20-inch or wider belt who would rather slide a long wand under it.

Where the numbers disagree: Garage Gym Reviews and BarBend list a 4 oz bottle, but one Walmart listing names a 2.9 oz tube. Check the size on the listing before you buy.

2. Impresa 100% Silicone Treadmill Lubricant: best value squeeze bottle

Why we picked it: Impresa sells a 4 oz bottle of 100% silicone oil in what it calls an EZ-Squeeze bottle, and the Amazon listing says it is made in the USA. Walmart carries single bottles and a 2-pack. BarBend estimates about eight applications per bottle on a full-size treadmill. A walking pad needs much less oil per session than a full treadmill, so one bottle goes a long way on a pad.

Key specs:

• Type: 100% silicone
• Size: 4 oz
• Applicator: squeeze bottle; some listings add a tube
• Made in: USA (Amazon listing)
• Applications per bottle: about eight (BarBend estimate)

Who should skip it: anyone who wants a long wand for a wide belt, where the Lube-N-Walk kit is the better fit.

Where the numbers disagree: a Walmart listing title says the bottle comes with an application tube, while Garage Gym Reviews reports the maker's view that an applicator tip is not needed. The eight-application figure is BarBend's estimate, not an Impresa claim.

3. LifeSpan Treadmill Belt Lubricant: best maker lube for under-desk treadmills

Why we picked it: LifeSpan builds under-desk treadmills such as the TR1200-DT3 (see our LifeSpan TR1200-DT3 review), so its own lube is the natural choice for those machines. The maker page lists a 3.4 oz bottle of 100% silicone with a straight tube tip and three disposable 6.5-inch applicators. LifeSpan describes the oil as colorless, odorless, non-toxic and nonflammable with no harmful solvents. It rates one bottle at three applications, or three months of normal maintenance, and its lubrication guide calls for 1 oz per application (2 oz after fitting a new belt).

Key specs:

• Type: 100% silicone
• Size: 3.4 oz (maker page)
• Applicator: straight tube tip plus three disposable 6.5-inch applicators
• Applications per bottle: three (maker figure)

Who should skip it: owners of wide full-size treadmills who lube often, since a larger Godora or Impresa bottle holds more oil.

Where the numbers disagree: LifeSpan's own page lists 3.4 oz, the Amazon listing title says 4 oz, and Treadmill Doctor describes an 8 oz squeeze bottle good for about eight uses. These may be different editions of the product, so go by the size on the listing you buy from.

4. Lube-N-Walk Treadmill Lubrication Kit: best kit with a long wand

Why we picked it: Lube-N-Walk, from JAD Fitness, says it has made treadmill lube kits since 1987. The home kit pairs 100% silicone lubricant with a long application wand that slides under the belt, so you reach the whole deck without lifting or loosening much. Horizon Fitness sells the kit on its own store as recommended for Horizon treadmill maintenance, and Lube-N-Walk sells 3, 4 and 6 oz refill bottles.

Key specs:

• Type: 100% silicone (maker)
• Applicator: wand, 24 inches per Lube-N-Walk
• Supply: "1 Year Supply" (maker wording)
• Refills: 3, 4 and 6 oz bottles
• Made in: USA (maker)

Who should skip it: walking pad owners with a 16-inch belt and little clearance, where a tube such as Noosa Life is simpler.

Where the numbers disagree: Lube-N-Walk's own page lists a 24-inch wand and a one-year supply, while Treadmill Doctor describes a 22-inch wand and a six-month supply. Lube-N-Walk also sells a Health Club kit, so check which kit a listing shows.

5. Godora 100% Silicone Treadmill Lubricant: best for bulk sizes

Why we picked it: Godora sells the same 100% silicone oil in 4, 8, 16 and 32 oz bottles across Amazon, Kmart and Sears listings. That range makes it the pick for a home or small office with more than one machine. The GoSupps listing for the 4 oz size names NordicTrack, SOLE, ProForm, Horizon, Weslo, True and Life Fitness as compatible brands.

Key specs:

• Type: 100% silicone
• Sizes: 4 oz (118 ml), 8 oz, 16 oz and 32 oz
• Applicator: not published on the listings we read
• Viscosity: not published

Who should skip it: anyone with a single walking pad, because a 16 or 32 oz bottle is far more than a pad uses at the 5 to 10 ml dose in KingSmith's manual.

Where the numbers disagree: the listings do not state an applicator type or viscosity, so we compared size and silicone content across the Amazon, Kmart and GoSupps listings. They agree on 100% silicone.

6. Horizon Fitness Silicone Lubricant 3-Pack: best for Horizon owners

Why we picked it: Horizon sells three bottles in one pack and states that "one bottle is good for two applications." It is also the only lube here whose maker page says where not to use it: "Do not use with Infinity Belts or Infinity Decks. This can cause increased deck friction." BarBend named it best overall in its lubricant roundup and describes a thick consistency.

Key specs:

• Type: silicone (100% per Garage Gym Reviews and BarBend)
• Pack: three bottles
• Bottle size: 50 mL (Garage Gym Reviews) or 1.7 oz (BarBend); not listed by Horizon
• Applications: two per bottle (Horizon)

Who should skip it: owners of Horizon machines with an Infinity Belt or Infinity Deck, and anyone whose manual names a different product.

Where the numbers disagree: Horizon says two applications per bottle, or six per pack, while BarBend estimates about nine per pack. Garage Gym Reviews lists 50 mL bottles and BarBend lists 1.7 oz, which are roughly the same amount.

7. SOLE Equipment Lubricant: best for SOLE owners

Why we picked it: SOLE's lubrication guide tells owners to "use only SOLE Equipment Lubricant, which is 100% silicone-based and made for treadmills," and describes it as food grade silicone. The product page lists it for SOLE treadmills, ellipticals, bikes, SRVO and rowers, so one bottle covers a SOLE home gym.

Key specs:

• Type: 100% silicone-based (SOLE guide)
• Size: not published on the product page
• Use: SOLE treadmills, ellipticals, bikes, SRVO and rowers

Who should skip it: anyone without a SOLE machine, because nothing in the published specs sets it apart from Impresa or Noosa Life.

Where the numbers disagree: third-party parts sellers list a SOLE lube under part number N020001 as 100% silicone, which matches SOLE's guide. We could not match that part number to the current product page, so we list only what SOLE publishes.

Also considered

TreadLube Silicone-Based Lubricating System: sold through Johnson Fitness and Wellness, Fitness Factory, Body-Solid and American Home Fitness as a wand with one multi-application cartridge, "designed for treadmills that use a silicone lubricant." None of those pages lists the cartridge size, the wand length or the silicone content, and Abt lists it as no longer available, so it did not make the picks. NordicTrack and iFIT Treadmill Maintenance Kit: three 0.5 oz lubricant packets, an applicator stick and a belt cleaner for NordicTrack and ProForm machines. BarBend lists the lube as 100% silicone, but the iFIT store page does not say. DuPont Teflon Multi-Use spray: BarBend's aerosol pick mixes silicone with Teflon (PTFE), so it is not a 100% silicone treadmill lubricant.

Silicone treadmill lubricant vs other types

Nearly every home treadmill and walking pad maker we checked names silicone. Sunny Health and Fitness explains why: silicone is "durable and doesn't break down under the forces generated by the moving parts." It does not dry out quickly and it has no strong smell. Garage Gym Reviews notes that most treadmill lubricants are 100% silicone oil or silicone-based.

The label matters. "100% silicone" means pure silicone oil. "Silicone-based" or "with silicone" can mean a blend with solvents, propellants or other lubricants such as PTFE. None of the manufacturers in this guide calls for a PTFE blend, and SOLE rules out "silicone caulking and anything with a spray- or foam-based formula." If you want one rule, buy a 100% silicone treadmill belt lubricant that says it is for treadmills.

Some belts and decks should get no lube at all. Horizon warns against using its silicone on Infinity Belts or Infinity Decks, and Garage Gym Reviews advises checking under the belt of a new treadmill first, because many come pre-lubricated. Your manual has the final word.

Why WD-40 and household oils are the wrong treadmill belt lubricant

Makers are blunt on this point. UREVO says 100% silicone treadmill oil "is the only oil you should ever put on your treadmill" and lists WD-40, 3-in-1 oil, motor oil and cooking oil as off limits, because "they contain solvents that melt the belt and ruin the motor." WalkingPad's guide says WD-40, vegetable oil and general-purpose silicone sprays "often contain petroleum distillates that can degrade the belt, attract dust, and negatively affect performance over time." SOLE's guide rules out generic lubricants, petroleum-based products and sprays like WD-40. NordicTrack tells owners not to use "oil or grease that have been manufactured for other purposes," because it may clog or damage the machine.

What about WD-40 Specialist Silicone? Garage Gym Reviews and BarBend say this non-petroleum spray suits many treadmills, but both tell readers to check the manual first, and SOLE and WalkingPad advise against sprays. A bottle of treadmill lubricant oil is easy to find and removes the doubt, which matters if you ever make a warranty claim.

What walking pad makers specify

Walking pad manuals tend to be short, but the ones we read agree on silicone. They differ on the amount, which matters because too much oil lets the belt slip.

The WalkingPad figures show why you should follow the manual for your exact model. The WPS1F manual says 5 to 10 ml, while WalkingPad's blog says one or two drops is enough. UREVO's 1 oz figure is for home treadmills in general, not for a specific walking pad. If your pad starts to slip after a lube, our walking pad belt slipping guide covers the fixes. Sunny adds a warning of its own: silicone that ends up on top of the belt is "notoriously difficult to get rid of," so a small, careful dose beats a big one. Owners of the pads in our KingSmith WalkingPad review and UREVO walking pad review can use any 100% silicone lube in this guide.

Treadmill lubricant spray vs applicator tube vs wipes

Applicator tubes and squeeze bottles give the most control. You feed the tip under the belt edge and meter the oil. Noosa Life's 10-inch tube and LifeSpan's 6.5-inch applicators fit the low frame of a walking pad well.

Wands such as Lube-N-Walk's and TreadLube's slide under the belt and spread oil across the deck. They suit full-size treadmills with belts 20 inches wide or more.

Treadmill lubricant spray in an aerosol can reaches far with little effort, but overspray can land on the belt surface, the motor cover or the floor. SOLE rules out spray and foam formulas, and WalkingPad warns against general-purpose silicone sprays. BarBend's view is that the delivery method does not change how the oil works, so choose by your machine's layout. For walking pads, where the manual dose is small, a tube is easier to keep under control.

Wipes and packets are rare. The iFIT kit uses pre-measured 0.5 oz packets with an applicator stick. We did not find a walking pad maker that names pre-soaked wipes as a lubricant.

Does viscosity matter?

Viscosity is how thick an oil is, measured in centistokes (cSt). Water is about 1 cSt. None of the maker manuals or guides we read names a viscosity, and none of our seven picks publishes one. Some Amazon sellers list 500 cSt or "multi-viscosity" silicone. BarBend notes that thicker oils, such as Horizon's, need less per session but can be harder to squeeze from the bottle. In practice, a 100% silicone oil sold for treadmills is the spec to look for. Do not chase a viscosity number your manual does not ask for.

How much a treadmill lubricant bottle covers

The table below is our arithmetic from the maker doses above. Real use varies with belt size and how carefully you apply it.

For one walking pad, a 3.4 or 4 oz bottle is plenty. Larger sizes make sense for full-size treadmills or several machines.

Where to buy treadmill lubricant

Amazon carries all seven picks. Walmart lists Impresa, Noosa Life and Lube-N-Walk. Maker stores sell their own lube: LifeSpan, Horizon and SOLE online, and Lube-N-Walk direct. Specialty parts shops such as Treadmill Doctor stock several brands, and Johnson Fitness and Wellness stores carry Horizon lube and TreadLube. Buying from the maker's store is the surest way to match the product your manual names.

How to choose the right treadmill lubricant for your machine

Walking pads and under-desk treadmills

Start with your manual. KingSmith's calls for silicone oil at 5 to 10 ml per session, and UREVO, LifeSpan and WalkingPad all point to silicone made for treadmills. Walking pads have belts around 16 to 17.5 inches wide and very little clearance under the frame, so a short tube or applicator works better than a 24-inch wand. Noosa Life's 10-inch tube reaches the center from each side, and LifeSpan's 6.5-inch applicators suit its under-desk machines. Buy a small bottle: at walking pad doses, 4 oz covers many sessions. If you are still choosing a pad, our best under-desk treadmill guide lists which models have maker lube guidance.

Full-size and folding home treadmills

These belts run 20 inches wide or more and take about 1 oz per session by UREVO's and LifeSpan's figures. A wand kit such as Lube-N-Walk reaches the full width without lifting the belt far. If you prefer a bottle, Impresa or Godora in an 8 oz size keeps you stocked for a year or more of sessions at that dose.

Machines under warranty

If the maker sells its own lube, use it. SOLE's guide says to use only SOLE Equipment Lubricant. Horizon sells its own silicone and the Lube-N-Walk kit, and warns against lubing Infinity Belts and Decks. LifeSpan sells a 100% silicone lube for its treadmills. Using the named product keeps things simple if you ever need warranty help.

Squeaks, noise and slipping

A dry deck can make a pad louder and work the motor harder, so lube is a common first check when a machine gets noisy; our guide to whether walking pads are loud covers other causes. Slipping after a fresh lube usually means too much oil, which is why the KingSmith manual caps the dose. Regular lubing is also part of what helps a pad last, as our guide on how long walking pads last explains.

Homes and offices with several machines

If you look after two or three pads, or a pad and a full treadmill, one large bottle of 100% silicone such as Godora's 16 oz size covers all of them, as long as none of the manuals names a specific product.

Safety and recalls

A search of cpsc.gov on 28 September 2026 showed no recall of treadmill belt lubricant from Noosa Life, Impresa, LifeSpan, Lube-N-Walk, Godora, Horizon, SOLE or TreadLube. The one recall we found tied to a brand in this guide covers treadmills, not lubricant: on October 27, 2022, the CPSC announced a recall of about 192,000 Horizon T101-05 folding treadmills with certain serial numbers, because they could speed up, slow down or stop without input. The remedy was a free software update from Horizon. Silicone on top of the belt or on the floor is a slip hazard, so wipe up any spill before you walk. Unplug the machine before you lube it and store the bottle away from children. If you own a Sperax pad, read our note on the April 16, 2026 CPSC warning before doing any maintenance.

How we researched this guide

We did not use these lubricants ourselves. On 28 September 2026 we compared maker product pages (LifeSpan, Horizon Fitness, SOLE, Lube-N-Walk, iFIT), maker guides and manuals (KingSmith WalkingPad WPS1F manual, WalkingPad, UREVO, LifeSpan, SOLE, NordicTrack and Sunny Health and Fitness support pages), retailer listings (Amazon, Walmart, Kmart, Treadmill Doctor, GoSupps, Johnson Fitness and Wellness, Fitness Factory, Body-Solid, American Home Fitness, Abt), independent roundups from Garage Gym Reviews and BarBend, and the CPSC recall database. Where sources gave different sizes or application counts, we say so in each product section. Read more in how we research.
