We don’t need to tell you that treadmills are an investment, especially if you opt for a high-end model with all the fancy tech features. And like anything else you spend money on, you probably want to protect that investment as best you can. In addition to cleaning the treadmill and tightening bolts when necessary, lubricating the belt is a vital part of regular maintenance. 

Doing so not only prolongs the life of your machine, it can also potentially fix annoyances like squeaking and belt hesitation. Most manufacturers recommend lubricating your treadmill once every one to three months, or every 30 to 50 hours of use. 

If you’ve never done this before, it’s natural to have questions (and we have answers). In addition to a bunch of tips for general treadmill maintenance, we’ve also put together a step-by-step guide on how to lubricate your treadmill. Of course, to effectively do the job, you’ll need one of the best treadmill lubricants first, which we’ve highlighted below.

Keep in mind that every treadmill is different, so while the recommendations here will work for many, it’s important to consult your user’s manual to make sure you’re choosing the right lubricant for your machine.

We’ve Lubricated A Lot Of Treadmills

During our testing, we’ve run hundreds of miles on dozens of the best treadmills on the market. Many of us also own treadmills of our own. Naturally, we’ve had to lubricate those treadmills regularly to keep them functioning as they should. We’d like to say this alone makes us experts in the subject, but our credentials—our testers are certified personal trainers, CrossFit coaches, and nutrition coaches—also help.

Other Treadmill Lubricants We Researched

Spot On 100% Silicone Treadmill Belt Lubricant

This treadmill lubricant has a lot going for it: It’s made in the USA of 100% silicone and has a precision twist cap that helps eliminate leaks and spills. Ultimately, it didn’t make the list because it’s more expensive than other similar options of this size and caliber.

Cartegory Food-Grade Silicone Belt Lubricant

This is another good option, but the bottles are smaller than most of our picks so you’ll have to repurchase more often. That’s the main reason it didn’t make our list. 

Lube-N-Walk Treadmill Lubrication Kit

This is a novel idea—it comes with applicators that lubricate your treadmill as you walk on it—but we think it’s easier (and cheaper) to just buy a small bottle of lubricant and quickly do it yourself.

GSM Brands Treadmill Belt Lubricant

You may be noticing a theme here: There’s nothing especially wrong with this treadmill lubricant, we just liked the options we picked better because they have more (and better) reviews. A plus side to this one? If you’re an artist, this lubricant has the right viscosity for acrylic pour painting.

How We Picked

It’s impossible to make a one-size-fits-all recommendation for treadmill lubricants since every machine is different. That being said, 100% silicone lubricant is a safe bet for many types of treadmills. Keeping versatility in mind, we focused on picks that had a clean ingredient list and didn’t contain any additives that could damage your machine. All of the picks can be used on budget-friendly treadmills to heavy-duty smart models.

We also considered user reviews. We made sure that most consumers were happy with the lubricant’s performance and didn’t have any major complaints.

We’ve also used a lot of these brands ourselves. We’ve had to lubricate many a treadmill and while we all have different favorites, collectively, we come back to the options on this list the most often.

Benefits of Using Treadmill Lubricants

Lubrication is a vital part of treadmill maintenance. 

“Without the proper lubrication, the deck and belt can rub, which creates excess friction that can damage the belt and the treadmill motor,” says Amanda Capritto, certified personal trainer and GGR editor. “Lubricant oil also keeps the belt supple so it doesn’t dry out and become brittle, which can drastically reduce the belt life.”

This is especially important to think about if you don’t use the treadmill often or it’s stored somewhere with a dry, high temperature. Keeping the belt lubricated also reduces noise as you run.

Buying Guide: What to Look for in a Treadmill Lubricant

Although it seems simple to just purchase a bottle of lubricant, there are a few things to consider. 

Ingredients

The ingredients are key when it comes to treadmill lubricants. The specific recommendation for your treadmill may differ slightly, but as a general rule, 100% toxin-free silicone lubricants are recommended. In addition to checking the main ingredient, you want to make sure the one you choose doesn’t have any additives or solvents that can damage the treadmill belt.

Application

Method of application is also important. Some lubricants come in a squeeze bottle, while others are aerosol-propelled. Some include an applicator tube or spout that makes it easier to perform regular maintenance, since you can get under the belt without loosening it as much.

Price

A single bottle of 4-ounce treadmill lubricant should run somewhere between $8 and $13. There may be some variation from this range, but you shouldn’t be paying much more than that. There are lots of options out there, many of which offer a similar product, so do some price comparisons before deciding on one.

FAQs About Treadmill Lubricants

Can I Use WD-40 Silicone On My Treadmill?

WD-40 Specialist Silicone, which is non-petroleum, is compatible with many treadmills (and other fitness equipment like ellipticals and rowers). Just make sure to double check the user’s manual for your specific machine before using it. If some spills on top of the belt, clean it immediately to avoid damaging the machine. Do not use regular WD-40, which is a petroleum-based product that can ruin the belt.

Is It OK To Use Silicone Spray On My Treadmill?

It’s okay to use silicone spray on many treadmills, but again: Check your user’s manual because it could be an expensive mistake if your machine isn’t compatible. Make sure you only get the spray under the belt, too. If you get it anywhere else, wipe it off as quickly as possible.

Can You Put Too Much Lubricant On A Treadmill?

Yes, it’s possible to put too much lubricant on a treadmill. If you do, you risk damaging the motor control board. Excess silicone can also fly out from under the belt as you run, splattering on your floors, walls, and anything it can touch. When lubricating a treadmill, start small and work your way up for best results.
