Best Wheel Bearing Grease – Ultimate Guide [Incl. Boat Trailers]

If you’ve just got yourself a used trailer or you need to maintain your current one, then you’ll need to get some good wheel bearing grease.

Why? Well, it’s simple. A good wheel bearing grease is a necessity for any wheels. This is because the bearings are in continuous use whilst you’re driving. A good grease can ensure that your bearings remain undamaged, and if you neglect them, then this can cause you problems further down the line.

Though the majority of wheel bearing greases are very similar, there are a few differences between them that you’ll want to know.

What’s the Best Wheel Bearing Grease in General?

The likelihood is that you don’t need a specific grease unless you’ve got a certain need. The majority of greases are interchangeable, but you need to consider what the best grease for your needs is. If you’re using the grease for bearings that won’t be moving much and are big and bulky, then you’ll want to opt for a heavy duty grease. Whereas if you’re looking for grease for your car brake bearings, then there are better options out there. Let’s have a look at some of the better options that are available.

Valvoline VV Series

Valvoline General Purpose Amber Grease 1 LB
  • Auto & Truck Maintenance
  • Country of manufacture: United States
  • Manufacturer: VALVOLINE
  • Product packaging may vary

I’ve been using Valvoline products for a long time and they’re still producing some my favorite products today.

Valvoline is one of the more well known names within the car maintenance industry, and their greases have been used worldwide. But does that necessarily make them the best option?

Well, if you’re looking for something that’s multi use, then you can opt for the Valvoline VV608 (link to Amazon) as your grease of choice. It’s great for a variety of uses, especially for vehicles and trailers.

If you’re looking for something a little more heavy duty, then you might be better off going for the Valvoline VV986 (link to Amazon). I personally use the VV986 for all of my vehicles (there’s 4 in the family) and some of my trailers too. I like it because it’s ideal for heavier loads and can take a lot of pressure, even with high and low temperatures.

Ideal for: Disc Brake Wheel Bearings, Car Suspension.

Lucas Heavy Duty

Lucas Oil 14.5 Ounce 10301 Heavy Duty Grease, 14.5 oz,Green
  • Lasts four times longer than regular grease
  • Virtually waterproof
  • All temperature stable
  • Exceeds lube for life specifications
  • Ultimate grease for high speed bearings

Lucas Heavy Duty Grease is certainly another option that you’ll want to consider if you’re looking for a grease that works with larger machinery.

With higher speed bearings, you’ll need something that’s going to last a little longer. While regular grease like the Valvoline should work fine, it’s not going to last long with the friction between the metals. You’ll find yourself having to grease up the bearings often, which can be a bit of a nightmare – you don’t want to spend your time re greasing your bearings consistently. But if you go for a heavy duty grease, then that grease is undoubtedly going to last longer.

When I’ve used this heavy duty grease, I haven’t had to consider greasing my bearings again for at least 6 months, but usually I make it an annual thing.

If you’re interested to read more about how the Lucas Heavy Duty compares to Lucas’ Red N Tacky, I wrote an article right here that goes into detail about those two offerings.

Ideal for: Trucks, Farm Equipment.

Mag 1 High Temp

Mag 1 723 High-Temp Disc Brake Wheel Bearing Grease - 14 oz.
  • The product is Mag1 HiTemp Brake Grease
  • Easy to use
  • The product is manufactured in China
  • Provides good pumpability in both hot and cold operating temperatures
  • Excellent resistance to water and water washout

I think I’d be doing Mag 1 an injustice by not mentioning their wheel bearing grease. It’s undoubtedly one of the more popular greases available on the market, so it’s definitely worth considering it if you need something that’s trusted by the market. I still have a tub of Mag 1 hanging around the workshop. And do you know why?

Well, it’s because you can use it on pretty much anything. There’s nothing that you can’t use this wheel bearing grease with, so it’s definitely worth considering it if you want something that is multipurpose. It works with a wide range of temperatures – even though it’s advertised as being a high temperature grease, it’s also very resistant to low temperatures too.

Another awesome choice for anyone looking for a solid wheel bearing grease that you can use for other stuff too, then you should consider Mag 1.

Ideal for: Multi Use.

What is the Best Boat Trailer Wheel Bearing Grease?

I have a multitude of different trailers that I use – I’m an outdoors nut, so I need a large amount of different trailers for all the things that I own (boat trailers, kayak trailers etc).

Depending on the type of trailer that you have, you may want a different option that suits you. For Marine greases, you’ll want to opt specifically for this type of grease as opposed to an all-purpose grease. This is because these marine greases are designed to work well no matter how we they get, whereas other greases may be affected by being submerged in water.

First, let’s start with my go to trailer grease that I use on a regular basis.

Lucas Oil Marine Grease

Lucas Oil 10320 Marine Grease; Multi-Purpose;14 Ounce
  • Brand: Tie Down Engineering
  • Part Number: 11008
  • Lucas Marine Grease 14 Oz
  • Great For Any Outdoor Enthusiast

You might be after something heavy duty that you can use for all your marine equipment – whether it be your boat itself, the trailer or your other on water stuff (water skis etc). If you want something that you can use for any of these things, then it might be worth opting for the Lucas Oil Multi Use Marine Grease. There are few more robust greases on the market than this one.

It’s made with a special lithium complex that you won’t find with other greases – using lithium helps to make it more substantial and less reactive with the metal that it comes in contact with. It has a weld point of 620kg – three times the recommended minimum. This means that you can be sure you won’t need to worry about the grease washing away when it’s underwater.

All in all, this is a fantastic option if you’re looking for a good marine boat trailer grease that isn’t particularly expensive, either. I also have another marine grease that I use occasionally and to be honest, there isn’t too much of a difference.

Ideal for: Boat Trailers.

CRC Marine Wheel Bearing Grease

  • Country Of Origin : United States
  • The Package Height Of The Product Is 4 Centimeters
  • The Package Length Of The Product Is 22 Centimeters
  • The Package Width Of The Package Is 16 Centimeters

Although CRC aren’t as well known in the grease industry as some other products that I’ve listed, they are undoubtedly one of the best options if you’re looking for some grease for your boat trailer. You might know CRC for more commonly producing brakes, which is one of their specialty products.

Why? Well, this particular grease used an extremely well refined oil as its base for conception. The grease is defined as tacky, which it is – making it really easy to apply, even for the novice wheel bearing greaser. Another thing that I like about this wheel bearing grease is that it’s blue – this means that you can see is very visibly when you’re applying it to your vehicle.

If you’re looking to completely prevent rust – a common problem with boat trailers – then you’ll want to opt for something highly refined like this CRC Marine Grease.

Ideal for: Boat Trailers.

Is Grease the Best Lubrication for Ball Bearings?

If you’re looking to lubricate your ball bearings, then the majority of people will tell you that you should get some grease for them. But, grease isn’t always necessarily the best option to lubricate your ball bearings. There are other options which might be more suited to your ball bearings, so it’s worth considering them as an alternative.

The reality is that around 90% of ball bearings are best off using grease as a lubricant. The other 10%, you would be better off using a good quality oil instead of the grease.

One of the main reasons that grease is a better choice than using an oil is that it will undoubtedly last a longer time than oil. Grease will have a longer lifespan in your wheel bearings than oil, which will need changing far more regularly than using grease.

Larger bearings generally need lubricating more often, so it doesn’t necessarily matter that the oil will run out quickly as they need more maintenance. Larger bearings usually work with larger machinery so they need to be faster – which makes oil a more suitable choice.

The consensus is that if you’re greasing your own bearings, then it’s a better option to go for a good quality grease as this will last longer. You won’t need to worry about using oil, or other solid film lubrications, if you’re just dealing with a regular bearing.

Why you shouldn’t use copper ‘grease’ for your bearings

It’s a common misconception that copper ‘grease’ is actually a grease that you can use for your bearings. It isn’t. 

Copper grease is actually an anti seize, and it’s definitely not intended to be used as a lubricant for your bearings. While you can use copper grease on your brakes in some circumstances, it’s definitely not intended to be used on your wheel bearings. Doing this is a good way to destroy your wheel bearings completely, or at least make them more clunky. I wrote more about copper grease as an anti seize in this article right here.

It’s a much better idea to get a grease specifically designed for your needs, and this really isn’t as difficult as it sounds. If you need something for your boat trailer, get marine grease. If you need something for your brake pads, then get the best grease for your brake pads, which I wrote all about here. Simple.


Of the greases that I actually use for my products, these 3 are undoubtedly my favorite. The Valvoline has been my number one grease for all my trailers for many years, and I’ve still never found an issue with their products. For my boat trailers, I prefer to opt for something waterproof, so I have both the CRC and the Lucas Oil products – they both work well.
