If you ride your ATV through mud, water crossings, dust, and snow, ordinary chassis grease washes out fast and leaves your bearings, ball joints, and CV boots running dry. The right grease stays put under pressure, shrugs off water, and holds up to the heat that builds in hard-working wheel bearings. The wrong one turns to soup at the first deep puddle and lets components grind themselves to failure.
We greased up wheel bearings, A-arm bushings, steering posts, prop shafts, and splined shafts across several quads and side-by-sides to see which products actually clung on after repeated water and mud exposure. Below are seven greases that earned their spot, ranked from our top overall pick down, with honest notes on where each one shines and where it falls short.

1. Lucas Oil Red N Tacky Grease: Best Overall
Lucas Red N Tacky is the grease we reach for first on an ATV, and the name tells you why. The tackifier package makes it genuinely stringy and sticky, so when you spin a wheel bearing or work a steering post it grabs the metal and stays there instead of flinging off the moment the wheels start turning. That clinginess is exactly what you want on a machine that vibrates hard and gets blasted with water and grit on every ride.
In wet testing it resisted washout better than most general-purpose greases, and the lithium complex base gave it solid load and temperature margin for wheel bearings and ball joints. The honest downside is the mess. That signature red dye stains everything it touches, and because it is so tacky it does not wipe up cleanly. It is also not a moly-fortified paste, so for splined CV shafts and drive splines you may still want a dedicated moly product. For everything else on the quad, it is hard to beat.
- Heavy tackifier makes it cling to bearings and pins instead of slinging off
- Strong water washout resistance for mud and creek crossings
- Smooth NLGI 2 consistency pumps easily through a hand grease gun
Pros: Exceptional stickiness that stays put under load and vibration; Holds up well in wet and muddy riding conditions; Works for nearly every grease point on the machine
Cons: The bright red color stains hands and clothing; Tacky texture can be messy to wipe up if you over-apply
2. Bel-Ray Waterproof Grease: Best Waterproof
Bel-Ray earned its reputation in the dirt bike and marine world, and that pedigree shows when you take an ATV through water. This grease is engineered to stay an emulsion-resistant grease even when submerged, so wheel bearings and pivot points keep their protective film after creek crossings that would thin out a cheaper product. If your riding involves serious water, this is the one that gives the most confidence.
It pumps and packs nicely, clings well, and holds up to the heat and load of hard trail use. The main drawbacks are practical rather than performance related. It usually ships in smaller containers, so if you grease a fleet of machines you will burn through it faster, and it is not always sitting on a local shelf the way the big auto brands are. For the rider who values true waterproofing above all else, those are easy trade-offs to accept.
- Built specifically for powersports and marine wet environments
- Aluminum complex thickener resists emulsifying when water gets in
- Clings tightly to bearings, pivots, and cables
Pros: Outstanding resistance to water and mud washout; Trusted powersports brand with a long track record; Stays stable across a wide temperature range
Cons: Comes in smaller tubs than many general greases; Tougher to source locally than mainstream auto-parts brands
3. Maxima Waterproof Grease: Best for Wet Riding
Maxima built this grease around a calcium sulfonate complex, and that chemistry brings two things ATV owners care about: real water resistance and standout corrosion protection. On parts that sit wet between rides, like wheel bearings and steering components, that anti-rust performance helps prevent the pitting and seizing that ends bearing life early. It also carries a high dropping point, so it does not melt and run out of a bearing that has been working hard on a long ride.
In use it stays put well, resists washout, and inspires confidence on machines that live in mud and snow. The honest weaknesses are minor. As a dedicated powersports product it sits at the higher end for value, and the thick, rich texture can feel stiff to push through a grease gun when temperatures drop near freezing. Warm the tube or the gun and that complaint mostly disappears. For wet-climate riders, it is a genuinely strong choice.
- Calcium sulfonate base delivers strong rust and corrosion protection
- High dropping point handles hot wheel bearings without thinning
- Formulated for powersports bearings, pivots, and linkages
Pros: Excellent corrosion protection for parts exposed to water; Resists melting out under high bearing temperatures; Stays tacky and in place under vibration
Cons: Premium powersports pricing relative to bulk auto grease; Thicker feel can be harder to pump in cold weather
4. Mobil 1 Synthetic Grease: Best Synthetic
If your ATV sees big temperature swings, from freezing winter trails to baking summer dunes, Mobil 1 Synthetic Grease is built for that range. The synthetic base oil stays fluid in the cold so it keeps protecting at startup, and it resists oxidation and breakdown in the heat, which means it holds up longer between greasing than many conventional products. For high-load wheel bearings on a hard-ridden quad, that stability is a real advantage.
Where it gives a little ground is raw water resistance. It is a capable, well-rounded grease, but against purpose-built waterproof powersports greases it does not cling quite as stubbornly through repeated deep water crossings. It also carries a premium over basic lithium grease. For riders who prioritize temperature range and long life over maximum mud-and-water staying power, it is an excellent and easy-to-find pick.
- Full synthetic base oil for broad hot and cold performance
- Strong oxidation stability extends regrease intervals
- Good mechanical stability under shock loads
Pros: Excellent performance across temperature extremes; Long service life thanks to synthetic stability; Readily available from a trusted name
Cons: Water washout resistance trails dedicated marine greases; Costs more than conventional lithium grease
5. Star Brite Waterproof Marine Grease: Best Value
Star Brite comes from the marine world, where staying waterproof is non-negotiable, and that focus transfers neatly to ATVs. Fortified with PTFE, it lays down a slick, protective film on wheel bearings, grease fittings, and pivots while resisting the water and even salt that would strip a lesser grease away. If you also tow your quad on a trailer, the same tub handles your trailer hubs, which makes it a practical do-it-all choice.
It earns the value badge because it delivers genuine waterproofing without a premium powersports price, but there are limits. It is tuned more for water and corrosion resistance than for the very highest bearing temperatures, so for race-pace, heat-soaked hubs a high-dropping-point grease has the edge. The texture is also a touch thinner and less aggressively tacky than the stringiest greases here. For everyday wet-weather trail riding, it punches well above its cost.
- PTFE fortification adds extra surface protection
- Marine formulation designed to resist water and salt
- Clings well to bearings, fittings, and trailer hubs too
Pros: Strong water resistance at a friendly value; PTFE content boosts anti-wear protection; Doubles for your ATV trailer bearings
Cons: Not specifically rated for highest-heat bearing duty; Thinner feel than some heavy tacky greases
6. Polaris Premium All Season Grease: Best OEM
There is something reassuring about greasing a Polaris machine with grease that Polaris formulated for it. This all-season product is built around the exact service points an ATV has, from wheel bearings to A-arm bushings to prop shafts, and it strikes a sensible balance between pumping easily in the cold and staying put when bearings heat up. For owners who like to keep everything by the book, especially during a warranty period, it removes any doubt about compatibility.
The trade-offs are about access and value rather than capability. As an OEM product it tends to cost more per ounce than aftermarket greases that perform similarly, and it is most readily found through dealer channels rather than the shelves of a general retailer. It is not dramatically more waterproof than the best aftermarket options either. But as a known-good, manufacturer-blessed grease for routine all-season service, it does exactly what it promises.
- Engineered by an ATV maker for ATV grease points
- All-season formula balances cold pumpability and hot stability
- Matches manufacturer service recommendations
Pros: Designed specifically for quad and side-by-side service; Good all-around water and temperature performance; Keeps warranty-minded owners aligned with OEM specs
Cons: Pricier per ounce than aftermarket equivalents; Easiest to find through dealers rather than big retailers
7. Valvoline Crimson General Purpose Grease: Best All-Purpose
Valvoline Crimson is the dependable workhorse of this lineup. As a lithium complex grease with a high dropping point, it shrugs off heat well and protects wheel bearings, suspension pivots, and steering components on an ATV just as capably as it handles the family truck. The vivid crimson color is genuinely useful in the shop, since you can see at a glance exactly where you have applied it and confirm full coverage on a fitting.
It is an all-purpose grease rather than a specialist, and that is both its strength and its limit. The water resistance is respectable for general riding, but it does not cling through deep, repeated water crossings the way the marine-focused greases here do. If most of your fittings, your quad, your mower, and your trailer should all run the same grease, this is a sensible single tube to standardize on. For the rider who wants one cartridge that does almost everything well, it closes out the list nicely.
- Lithium complex base with a high dropping point
- Bright crimson color makes coverage easy to see
- Adaptable across automotive, ATV, and equipment fittings
Pros: Reliable everyday protection for most grease points; Strong heat resistance for the price; Widely available in convenient cartridges
Cons: Water resistance is good but not marine-grade; Less specialized than dedicated powersports greases
Frequently Asked Questions
What kind of grease is best for ATV wheel bearings?
For ATV wheel bearings, look for an NLGI 2 grease with strong water washout resistance and a high dropping point, since wheel bearings get both wet and hot. A tacky lithium complex grease like Lucas Red N Tacky or a dedicated waterproof powersports grease such as Bel-Ray or Maxima is ideal. These cling to the bearing under high speed and vibration and keep their protective film even after you splash through water, which is exactly what wheel bearings need to avoid premature wear and seizing.
Can I use regular automotive grease on my ATV?
You can use quality automotive lithium complex grease on many ATV points, and a product like Valvoline Crimson works fine for general lubrication. The catch is environment. ATVs see far more water, mud, and dust than a typical car, so a grease that is merely good enough for a sealed automotive chassis can wash out of an exposed quad fitting. If you ride through water or mud regularly, a marine-grade or powersports-specific waterproof grease will protect your bearings and pivots much longer than basic automotive grease.
Do I need special moly grease for CV joints and splined shafts?
For CV joints, drive splines, and slip yokes, a moly-fortified grease or moly paste is the preferred choice because the molybdenum disulfide handles the sliding, high-pressure contact those parts experience. Many of the greases in this guide are excellent general-purpose and wheel-bearing greases but are not heavy moly products. A good approach is to keep one quality waterproof grease for bearings and pivots and a separate moly paste for CV and spline service. Always check your owner manual, since some manufacturers specify a particular product for these points.
How often should I grease my ATV?
A good rule of thumb is to grease the fittings every time you wash the machine or after any ride that involved deep water or heavy mud, and at minimum at every oil change or service interval. Water and grit are the enemies of ATV grease, so frequent riders in wet conditions should regrease often, pumping fresh grease through each fitting until clean grease pushes out the old, contaminated grease. Sealed wheel bearings without fittings should be inspected and repacked or replaced according to your service schedule or whenever you feel roughness or play.
Is waterproof grease really necessary for an ATV?
If you only ride on dry trails and never cross water, a standard high-quality grease will serve you well. But for the vast majority of ATV owners who deal with mud, puddles, creek crossings, snow, or washing the machine down regularly, waterproof grease is well worth it. Water-resistant greases like Bel-Ray, Maxima, and Star Brite resist emulsifying and washing out, which keeps a continuous protective film on your bearings and joints. That directly translates to longer component life and fewer expensive bearing or ball joint replacements down the road.
Our Verdict
For most ATV owners, Lucas Oil Red N Tacky Grease is our top pick thanks to its outstanding stickiness, strong water resistance, and ability to handle nearly every grease point on the machine. If your riding is especially wet, our runner up, Bel-Ray Waterproof Grease, is the one to grab for its marine-grade, emulsion-resistant protection that simply refuses to wash out. Pair either with a dedicated moly paste for your CV joints and splines, grease often, and your bearings and pivots will reward you with many trouble-free miles.
