Our Best Grease For RV Trailer Bearings Reviews

1. Lucas Oil 10320 Multipurpose Marine Grease

Perhaps one of the best options out there right now, Lucas Oil 10320 Multipurpose Marine Grease can be used for a variety of applications, which of course includes lubing up the bearings in your RV trailer. The fact that it is marine grade grease actually makes it perfect for this kind of thing, and it doesn’t even cost all that much, either.

Review

When you purchase Lucas Oil 10320 Multipurpose Marine Grease, you get a 14 ounce bottle, which for the price it comes in at, is actually quite the bargain. This is a premium, heavy duty lithium complex grease with a special additive.

The main point to keep in mind here is that this is actually marine grease originally designed to be used with big ships and the like. In other words, it has the ability to deal with extreme loads, has a dropping point of 540 pounds, and a Timken load of 80 pounds.

In other words, when it comes to stress and friction, Lucas Oil 10320 Multipurpose Marine Grease is one of the best options to go with. In terms of extreme temperatures, this product will work in pretty much any weather conditions known to man.

This grease is meant to work in the most severe of marine conditions. One bonus here is that it is resistant to saltwater and helps prevent corrosion, which can come in handy for RV trailers as well.

This product also lasts for a really long time, so it does not need to be applied often. With that being said, the tube it comes in doesn’t make application very easy. 

Pros

  • Works in extreme weather
  • High grade lubrication
  • Multipurpose
  • Does not need to be applied often

Cons

  • Not very easy to apply

2. Sta-Lube SL3121 Wheel Bearing Grease

Yet another good option to go with, Sta-Lube SL3121 Wheel Bearing Grease is actually quite similar to the first one which we looked at. It is technically marine grease, but can be used for all sorts of applications. Once again, this product is actually fairly inexpensive, considering how much of it you get.

Review

Here you get a 14 ounce container of Sta-Lube SL3121 Wheel Bearing Grease, and the price is just a couple of dollars higher than the first option on our list here today. Yes, this is a multipurpose grease that can be used for axels, bearings, 4x4s, trailers, boats, outboard motors, and other such things.

The big benefit of being marine grade grease is the fact that it is highly water resistant and lasts for a long time to come. Sta-Lube SL3121 Wheel Bearing Grease only needs to be applied every few months at the very most, and it is made fairly thick so it stays where it is put, and it lasts for a long time too.

The fact that it resists washing off, and even resists and prevents corrosion, is a pretty big bonus, too. This is a fairly high quality grease that can be used for a variety of purposes, one that will work in all weather and water conditions without fail.

Also, if there are other substance or lubricants present, it will not blend or mix with them; yet another big bonus no doubt. With that being said, it has a bit of an odd consistency that makes applying it a bit of a pain, not to mention that it does not smell very nice either. 

Pros

  • Resists washing off and corrosion
  • Multipurpose
  • Works in extreme weather conditions
  • Does not blend

Cons

  • Bad smell
  • Application is not easy

3. Star Brite Wheel Bearing Grease

This is actually the least expensive option on our list so far today, coming in at a couple bucks cheaper than the first option we looked at. Star Brite Wheel Bearing Grease may not be expensive, but you still get a whole lot of high quality grease that can be used for a multitude of purposes.

Review

If you are worried about lubrication washing off due to lots of rain and extreme weather, with Star Brite Wheel Bearing Grease, you do not have to worry. It is specially designed to resist washing out, as it is technically marine-grade grease.

It is designed to be used with items that get wet all of the time, and therefore will not wash off, which does also come in handy for RV trailers. Moreover, if you are worried about corrosion and oxidation, Star Brite Wheel Bearing Grease takes care of that as well, as it is designed to work with saltwater.

Your RV and trailer components are not about to get rusty when you use this product. On that same note, things can get really cold at sea, which is why Star Brite Wheel Bearing Grease is made to resist extreme cold, but can also work in extreme heat, not to mention that it has a huge load capacity.

This is indeed a fairly high quality grease that can be used for trailer wheel bearings, hinges, pins, water pumps, axels, winches, and so much more. You will require a grease gun to apply this particular grease.

Also, it can be a little thin, especially when warm, which decreases its effective shelf life after application. 

Pros​​​​

  • Very high quality
  • Works in extreme temperatures
  • Resists washing out
  • Stops corrosion

Cons

  • Requires a grease gun to apply
  • Can be a bit thin in warm weather

4. Lucas Oil 10301 Heavy Duty Grease

Coming in at over $20, this is by far the most expensive option on our list. However, with that being said, you do get what you pay for, and here you get super heavy duty grease that lasts for a really long time.

Lasting much longer than most others, it can be used for a variety of applications, and it works in pretty much all weather conditions too.

Review

Lucas Oil 10301 Heavy Duty Grease is actually one of our favorite options to go with. Although it is a bit pricey, we think it is well worth investing a few extra dollars for a product that works as well as this.

Perhaps the best aspect of Lucas Oil 10301 Heavy Duty Grease is that it is quite thick and specially designed to last for a very long time. It is advertised as being able to last up to four times longer than most other grease options.
-
This product can be used for heavy duty automotive, industrial, and agricultural applications. In other words, if the machine or item in question has bearings, Lucas Oil 10301 Heavy Duty Grease can be used to grease them up.

This particular grease is made to be virtually waterproof, so it resists washing out even in heavy rain storms. At the same time, it is also able to work in both extreme heat and cold.

Now, one thing that needs to be mentioned is that this stuff is not designed to resist corrosion or to deal with saltwater, so it might not be best if you are taking your RV for a trip along the coastline.

Pros

  • Very long lasting
  • Great consistency
  • Can work in any weather and temperature

Cons

  • Does not deal with saltwater very well

5. Allstar ALL78241 Timken Brand Premium Red Type Wheel Bearing Grease

This final option is another fairly affordable one. Allstar ALL78241 Timken Brand Premium Red Type Wheel Bearing Grease can be used for all kinds of automotive axels, bearings, and other moving parts, too.

Review

Allstar ALL78241 Timken Brand Premium Red Type Wheel Bearing Grease is specially designed to deal with very high loads, high amounts of friction, and extreme heat, too.

Yes, things can get hot when the bearings get spinning, but this product is specially designed to handle that heat. It won’t get too hot and it won’t run off the bearings due to the heat.
 
Not only that, but Allstar ALL78241 Timken Brand Premium Red Type Wheel Bearing Grease is also water resistant, not waterproof, but water resistant. It should work fine for RVs and trailers, but don’t use it for marine applications.

On that same note, this product is also corrosion resistant, which definitely comes in quite handy.

Now, while this product can handle extreme temperatures, most types of weather, and heavy loads, beware that the container it comes in makes it a bit hard to apply, plus its consistency means that you might have to reapply it more often that you would like. 

Pros

  • Can resist extreme heat and friction
  • Works in most weather conditions
  • Multipurpose

Cons

  • Hard to apply
  • Need to be applied fairly often

Conclusion

When all is said and done, although it sounds odd to use marine grease for trailer bearings, it actually works really well due to the fact that marine grease resists water, heat, corrosion, and extreme temperatures.

So, when it comes down to it, we would recommend using any of the marine grease options we have reviewed before anything else.
