If you have a treadmill in your house, you probably use it all the time. But did you know that you’re supposed to maintain it as well? If you’re not taking care of your treadmill, then it could break down, leaving you with an expensive piece of non-functional decor.

How to Choose Lubricant for Treadmills


Depending on how often you use your machine, you may have to lubricate it several times per year. According to most manufacturers, the recommended lubrication schedule is about every three months or 40 hours. That being said, if you only use the treadmill a few times in those three months, you’re probably fine regardless.

Because of this routine, it’s best to get a lubricant that has a sufficient amount so that you don’t have to buy more that often. Usually, one treatment is about one ounce, so try to get a bottle that’s at least four ounces so that you can replace it annually (assuming you’re using your treadmill regularly).

In some cases, you may be able to find smaller or bigger bottles, but you don’t want to get too much more than you need. Lubricant does have a shelf life for how well it will work, so don’t assume a giant jug will last you for years to come.

Can You Use Any Lubricant On A Treadmill?

If you look at most treadmill manufacturers, they will recommend that you only use 100% silicone when lubricating your machine. The reason that silicone is preferred is that it lasts a long time and doesn’t break down. Not only that but unlike other ingredients (like oil), this substance will not affect the machine either.

Overall, buying the right lubricant for your treadmill will be the best option, rather than trying to figure out a solution using other ingredients. Assuming that you want to keep your machine in tip-top shape, you should follow our (and the manufacturer’s) recommendation.

Can I Use WD 40 Silicone On My Treadmill?

If you try putting oil or some kind of chemical (like WD-40) on your treadmill, you will cause premature wear and tear. Some people may recommend Teflon (a silicone-based synthetic), but you shouldn’t use it unless directed to by the manufacturer.


When picking out the best lubricant for your treadmill, you should pay attention to how it can be applied. We’ll get into the primary steps needed to lubricate your machine, but the basic premise is that you want something that is both easy and effective.

As we mentioned, you only need about one ounce of lubricant when working on your treadmill, so it’s crucial that you don’t overdo it when working. To ensure that doesn’t happen, you need an applicator that won’t create a mess.

The other thing to consider is whether you can lubricate the belt without pulling apart the machine. While loosening screws and bolts may be necessary, it can add wear and tear to the unit, which can make it more prone to breaking down on you.

Some applicators will come with a specialized attachment or hose to let you get under the belt without doing anything else, but this process can also be tricky because you can’t see what you’re doing or how well the lubricant is being distributed.


How To Lubricate Your Treadmill

Once you have found the right lubricant for your machine, it’s imperative that you follow the right steps to ensure a smooth and proper experience.

Where Do You Put The Lubricant On The Treadmill?

Read the Manual: before doing any kind of maintenance on your treadmill, you should go over the manual to see if there are any particular recommendations. Also, this will give you a chance to see what other maintenance you can do to keep it in prime working condition. If you don’t have the manual, you can look online based on the serial number of the machine.

Don’t Over Lubricate: some treadmills come pre-lubricated, which means that you could be causing damage if you add more before it’s time. This information should be available in the manual as well, adding another reason to check it first.
Lubricate Before Long-Term Storage: if you’re saying goodbye to your treadmill for a while (i.e., six months or more), then it’s a smart idea to lubricate it beforehand so that the belt won’t become brittle and crack while in storage.

When lubricating your treadmill, you will want to keep the unit plugged in so that you can spread the material around by running the belt.

If you have to loosen the bolts to get underneath the belt, it’s critical that you tighten everything back up afterward before turning the machine on. This will ensure that you don’t accidentally break anything.

We suggest using a flashlight to see under the belt and make sure that you’re getting all the way across. If the lubricant is only staying on one side, it could weaken the belt and cause it to fail nonetheless.

Keep a towel handy and place one underneath the treadmill just in case of spills. Having the proper applicator can minimize this problem, but it’s still a good idea. Also, having a towel will enable you to clean up any extra that comes out on the sides of the belt.

Finally, avoid getting any lubricant on top of the belt. Because it’s slick, it could create a hazard for you next time you use the treadmill. Wipe off any material that drips on the belt immediately so that it won’t seep in.

Recommended Lubricant for Treadmills

Spot On 100% Silicone Treadmill Belt Lubricant

As we mentioned above, most treadmill manufacturers highly recommend applying nothing but silicone for lubrication. If you’re not going to use 100% silicone, you could cause premature wear and tear on your machine and create more problems than you’re trying to solve.

Fortunately, this version from Spot On is 100% silicone, so you don’t have to worry. This material is non-toxic and odor-free, making it a safe way to lubricate your treadmill. Don’t worry about any off-putting smells while working on your machine, and don’t worry about pets licking up excess by accident.

Because the lubricant itself will be the same across all of these different models, the primary thing to pay attention to is the bottle and cap. In this case, we have a squeeze bottle that has a precision twist cap, allowing you to add just enough lubrication without going overboard.

If you want more control over this process, then you can buy a hose applicator from Spot On. While this will be a separate purchase, it could be worth the additional investment because of the convenience it provides.

What we like most about this lubricant is that it comes with a 100% money-back guarantee. If you’re not satisfied when you use it, you can get a replacement in no time. Buy it with confidence.

IPO Multi-Purpose Lubricant

For the most part, if you buy treadmill lubricant in a squeeze bottle, you can expect it to be short and fat. While there isn’t necessarily anything wrong with this configuration, it can be a little tricky to apply the substance, especially as you use it up over time.

Because of this issue, we like this lubricant from IPO. Rather than providing you with yet another short and fat bottle, this one is elongated to give you more control while working. Although we would prefer for this unit to come with an applicator hose, the precision nozzle coupled with the slimmer profile does make it easier to handle overall.

Otherwise, this lubricant is about the same as the others. It’s made of 100% silicone for a smoother result while walking or running, and you get four ounces of the stuff, which should last up to a year or so. Because it’s silicone, you don’t have to worry about extra chemicals in this lubricant, such as propellants or distillates. It’s the real deal.

Finally, this unit does come with a satisfaction guarantee, meaning that you don’t have to worry about buyer’s remorse.

Horizon Fitness Silicone Treadmill Belt Lubricant

So far, we’ve seen lubricants that come in a (relatively) large bottle, meaning that you can use the same unit for multiple applications. However, the primary issue with this is that it’s challenging to figure out how much to use each time. While one ounce is recommended, how can you be sure that you’re squirting a whole ounce? What if you accidentally put more?

To alleviate this issue, we have a set of three applicator bottles designed for single use. While you don’t get a full year’s supply, they do come with measurement readings on the side so that you can be sure you’re applying the right amount.

The other issue we’ve seen with these lubricants is the fact that they can leak. In this case, the tips are fully sealed (you have to cut them beforehand), ensuring that you don’t lose any silicone before you get a chance to use it.

Overall, while these smaller bottles can be a little harder to handle, they are worth the added precision and control.

  • Three applicator bottles
  • Measurements on the side for precision
  • 100% silicone lubricant
  • Precision nozzles for convenience
  • Squeezable tube
  • Leak-resistant design
  • Tips have to be cut before using
  • Can be hard to apply due to the smaller size

Final Verdict

Because all of these lubricants are made of 100% silicone, it’s difficult to say whether one brand is necessarily better than the other. However, we can safely decide that the Impresa is our top pick, all thanks to the squeezable bottle it comes in.

We like that you can apply your lubrication without having to loosen the bolts and cause wear and tear on your machine. Impresa makes this process much simpler and ensures that treadmill maintenance is as quick and painless as possible.
