    Best Grease Reviews & Recommendations 2020

    Best Overall

    The Valvoline Synpower Grease is one synthetic grease that can take heavy loads and still preserve its effectiveness. This is due to the fact that it’s a moly-fortified grease, meaning that the product has great film strength to endure lots of weight. It’s best used in the ball joints of heavy-duty trailers and trucks. It’s also fortified for extreme pressure and can be used on most farm equipment, including farm tractors. 


    The product is heat-fortified and remains stable with no bleeding or hardening issues at temperatures ranging between minus 60 to 425 degrees Fahrenheit. It also includes rust and oxidation inhibitors to preserve the life of the metal it’s applied on. Lastly, the grease is relatively thin and pumps well out of a regular grease gun. 


    Despite all the fortification that the Valvoline grease enjoys, the components can still separate after prolonged storage. You may notice a leaking bottle if it sits for too long on the shelf. Moreover, it’s not designed for marine use.

    Best Value

    The Lucas Oil Heavy-Duty grease is something you need in your corner if you reside in areas where the temperatures go above 110 degrees Fahrenheit. It remains stable at all temperatures without bleeding or drying. The manufacturer includes a polyurea base to make the product last four times longer than regular grease.


    The grease is virtually waterproof and plastic-safe. It can be used as a lubricant in steering systems, U-joints, and any other mechanical joint. It’s a great choice for high-speed bearings, heavy-duty farm equipment, and construction equipment.


    Unfortunately, it’s not the best product for extreme pressure conditions, such as an automotive brake system. What’s more, it may not last on marine equipment that’s frequently exposed to large amounts of water and salt. The components may also separate when mixed with a lithium complex.

    Honorable Mention

    The Maxima Waterproof Grease is a smooth, dark blue, lithium-based, multi-purpose grease. It’s designed with a high-density polymer that helps the grease to remain stable at temperatures ranging from minus 20 to 560 degrees Fahrenheit. During such conditions, it won’t thin or harden under normal usage. 


    The grease works to lubricate metal surfaces to reduce friction, while at the same time efficiently resisting water or moisture penetration. It’s further engineered with non-leaded extreme pressure additives to preserve its protective properties under high-load carrying and shock-loading conditions. What’s more, it features rust and corrosion inhibitors for superior performance under harsh operating conditions. 


    However, the grease comes in a semi-solid state in a jar and applying it can be messy, especially when you try to stuff it in a grease gun. It’s also quite sticky and attracts dirt and grit, which may thin it and reduce its effectiveness as a lubricant.

    Benefits of Grease 

    • Reduce friction. The primary use of grease is to reduce the friction of moving parts. If moving metal parts are left to slide over each other without lubrication, it will lead to faster wear and consequently mechanical failure of the components. For instance, an unlubricated bike chain will eat at the gears and eventually snap. 
    • Protection. Grease forms a protective layer on metal parts and keeps out water, dust, and other contaminants that may damage the parts. It also seals in the old grease and any oils that were pre-applied for lubrication. 
    • Reduce noise. Wheel bearings, bike chains, and gears can get noisy if not lubricated. Packing the parts with grease helps the moving parts to slide over each other more quietly. 
    • Smooth operation. Grease maintains the mechanical stability of the applied surfaces and facilitates the smooth movement of the moving parts. Since you don’t have to worry about rust, friction, or corrosion, you can expect your equipment to work efficiently during slow operation or high-pressure conditions. 

    Types of Grease 

    Ion-Based

    The ion bases used to make grease are mainly sodium, aluminum, calcium, barium, and lithium. The grease could contain about three percent of the base and the other portion is acquired from mineral oils, vegetable oils, synthetics, or other additives. The end result is typically a multi-purpose grease with a high tolerance for extreme temperatures and great water-resistance. 

    Marine

    Marine grease is typically used on marine equipment owing to its water- and salt-repellent properties. It’s commonly used to facilitate gliding movements when metal is operating underwater, like an anchor chain for instance. It can also be used on motorcycle chains,  steering cables, door hinges, and disc brakes. 

    Moly EP

    Moly EP grease is made from molybdenum disulfide. The compound gives the final product a high melting point and corrosion resistance. The EP on the name stands for extreme pressure, denoting that the grease can tolerate extreme pressure conditions. It’s mostly used on metal surfaces subjected to heavy loads or high pressure such as wheel bearings or ball joints. 

    Disc and Drum

    Disc and drum grease is water-resistant and formulated with a high melting point. It can withstand extreme temperatures generated from fast-moving wheels and instant pressure exerted by the brakes. It can be used on the wheel bearings of almost any vehicle.

    Grease Pricing

    • Under $20: Grease products are typically priced according to its properties and the size of the bottle. For that reason, this price range includes small bottles and tubes of general-purpose greases ranging from 3.5 to 14 ounces. Most of the grease bottles don’t come with an aerosol tip and you'd have to purchase an application gun separately. 
    • Over $20: This price range includes some high-performance greases and some of the products in the lower price range but in larger containers. For the high-end options, you can expect greases with high melting points, recommendable viscosity ratings, and superb water and dirt repulsion capabilities. 

    Key Features

    Temperature Stability 

    Poor-quality grease hardens in low temperatures and bleeds at high temperatures. That can be messy and wasteful. You want a grease that remains stable even when the temperatures dip below minus 40 degrees Fahrenheit, and can withstand the highest temperatures in your region.

    Pressure Performance 

    Too much pressure can cause grease to thin or shear. This can happen during shock loading or when you apply emergency brakes. Under such conditions, the greased parts come in contact and corrode each other. Your best bet would be to use EP greases that have graphite or molybdenum disulfide, which bonds to the metal surface to prevent contact during extreme pressure conditions. 

    Viscosity 

    Viscosity is a measure of the ability of a fluid to resist flow. For an automotive grease, you need something soft that can lubricate and facilitate easy movement of the mechanical parts. Figuring that viscosity is measured at a rate of zero to six, the grease should be at a two. This would feel like soft peanut butter when rubbed on your hands. 

    Water Resistance 

    When metal parts are in constant contact with each other, the last thing they need is water since it can cause the parts to rust and fall apart. This is why you need a water-resistant grease that forms a protective film on the applied surface to keep the water out. 

    Other Considerations

    • Additives: Grease with extra additives like copper or ceramic powder can improve its high-temperature performance, and protect from component damage throughout their service life. Glycerol additives can help with low-temperature tolerance. 
    • Versatility: Choose a greasing product that can suit different applications. You can have one product that can be used on your automobiles, farm equipment, and domestic appliances. 
    • Ease of Application: Prioritize greases that come with spray applicators or tubes that can be easily loaded into a grease gun for easy application. If it comes in a jar, ensure that it’s not too sticky or drippy for application. 
    • Shelf Life: In case you are buying in bulk, choose a product with a long shelf life. Consider how often you will be using the grease and choose a product that fits that time frame. Otherwise, you will be left with leaking products on the shelf.

     Tips

    • A water-resistant grease will offer effective shielding against water drops and moisture. This property also helps to protect the metal parts more effectively against corrosion.
    • A grease that can withstand extreme temperatures will not break down easily. Temperatures in automobile bearings can get high, so choose a grease that can operate within a large temperature range.
    • The viscosity of grease makes it thin or extremely thick. For automotive use, a viscosity rating of two is an ideal choice, as it makes application easy.

    FAQs

    Q: What are multipurpose greases?

    A: These greases combine some of the best properties of other special greases. This makes them suitable for a wide variety of applications. Lithium-based greases are popular as multipurpose grease.

     Q: How long can I store unused grease?

    A: When stored for long periods under poor conditions, grease can go bad. Often the oil and solids in the grease separate, making it unusable. Check the guidelines from the manufacturer for storing the grease.

     Q: Can I mix two types of grease?

    A: It is best not to mix two different types of grease. In many cases, thickeners and additives in two different greases can be incompatible with each other. This will make the mixture ineffective as a lubricant.
