An NLGI #2 certified grease built to handle wheel bearings, boat trailers, and suspension duty without washing out.

This is the true all-rounder for anyone who works on cars, trucks, or marine equipment and wants one bucket that does it all without compromise. The AtomLube meets the NLGI performance classification GC-LB — that is the highest industry standard for both wheel bearing and chassis grease applications. It comes as a 2-pack of 14 oz. tubes, giving you twice the volume of many competitors, so you can load one into a grease gun and keep a spare on the shelf.

The adhesion is the key feature here: this grease develops strong stay-in-place power on metal surfaces even under high-pressure water spray, which is why buyers report using it on mowers and suspension parts without it slinging off. Unlike the thin spray of the WD-40 Specialist below, this is a heavy-duty NLGI #2 grease intended for a grease gun — not a quick lube can.

Owners mention it loads easily into a pneumatic grease gun and holds up well on lawn equipment, though one buyer simply called it “good grease” without elaboration. The catch: this is a lithium-based grease, so it should not be used on rubber brake caliper boots or plastic slider pins — that is where a ceramic or silicone grease like the Keze brake grease is safer.

A quick-drying silicone spray that slips into tight spots without leaving a greasy mess behind.

If your problem is a door seal that sticks to the frame, a wiper blade that chatters, or a plastic trim piece that squeaks against the dash, this is the lubricant you want. Unlike thick lithium greases that leave a visible residue, this silicone spray dries quickly and leaves no oily film — one reviewer noted it made his garage door open smoothly after a bracket broke from sticking rubber gaskets. The twin-pack gives you two 11 oz. cans, and each can has the Smart Straw that sprays two ways: a wide pattern or a precise stream.

At 12.8 ounces per can, the weight is similar to the 14-ounce tub of the Red And Tacky grease, but the comparison stops there — this is a completely different tool for a different job. The WD-40 Specialist formula is safe on rubber, vinyl, and plastic, which means you can use it on engine bay hoses and weatherstripping where a petroleum-based grease would cause swelling. It also waterproofs the surface, making it a good choice for outdoor locks, hinges, and even the rubber gasket on a kitchen disposal, as one reviewer found.

The honest limit: this is a light lubricant, not for heavy bearings or brake parts. One buyer mentioned it helps “remove dirt and makes things run smoothly,” but a loaded suspension joint needs a much thicker product like the AtomLube above. The spray can also runs out faster than a tub of grease if you are doing a large job.

A purple, paint-like grease that sticks to brake pins and sliders to stop squeals and prevent future seizing.

Dedicated brake grease is not a luxury — it is the difference between a brake job that takes 30 minutes and one that takes two hours with a torch. This Keze ceramic grease is formulated specifically for caliper pins, pad sliders, and brake hardware. Unlike a general-purpose lithium grease, it uses ceramic powder and synthetic MCA (a type of thickener) that does not swell rubber boots or evaporate under the high heat of hard braking.

Customers note exactly the outcome you want: “eliminated sticky calipers and uneven wear,” providing smooth, vibration-free braking with no squeaks. The bottle has a brush-top applicator, which makes zero-mess application onto pins and pad backs much easier than dipping your finger into a tub. At 8 oz, a single container lasts several brake jobs — one owner reported a small amount covers multiple jobs. The 8 oz volume matches the Keze copper anti-seize below, but do not swap them: the ceramic grease is for sliding surfaces, while the copper compound is for threaded fasteners that face 1800°F exhaust heat.

The slight catch: this is a liquid form that clings thickly, so you need to let it set before assembly if you apply heavily. Also, it is specifically a brake grease — not a multi-purpose lube for bearings or chassis points.

A thick, fortified lithium grease that clings to bearings even under extreme pressure and heat.

This Red And Tacky grease from GREASECO is exactly what its name promises — a heavy-duty, extra-tacky grease that stays put. It is built on a fortified ISO 460 base oil, which is heavier than the base oil many competitors use. That means it provides better extreme pressure and anti-wear protection for high-load components like wheel bearings, tie rods, ball joints, and CV joints. A buyer confirmed it: “thick, tacky lithium grease in 1 lb tub” that fixed squeaking control arms on a Tesla Model 3.

At 16 Fluid Ounces, compared to the 8 oz Keze copper grease below, this is a generous amount — one reviewer even joked that he bought a pound and “will never need to buy grease again.” It resists water and extreme temperatures, and the advanced EP (extreme pressure) additive package protects metal surfaces against shock loads. The box lists use across construction, mining, agriculture, marine, and dozens of other industries, showing its range.

The honest trade-off: a few buyers with chemical sensitivities report the fragrance is strong — one called it “a odor from hell” for those sensitive to it. Also, lithium grease is not for rubber brake caliper boots; stick to the Keze ceramic above for that job. If you need a heavy grease for suspension and bearings and do not mind the smell, this tub is a phenomenal value at 16 oz.

A tiny tube of synthetic grease that rescues sticky fans, keyboard stabilizers, and dry hinges.

Do not be fooled by the size — this 0.5 oz tube of Super Lube is the most versatile synthetic grease in many a toolbox. It is dielectric (non-conductive), waterproof, and rated as a food-grade lubricant, so you can use it on a kitchen blender, a 3D printer’s lead screw, or a vintage computer’s floppy drive mechanism without worry. Reviewers point out using it to fix a Bionaire tower fan after cleaning — “works like new, suitable for high-speed rotation and Arizona summers.”

Because it is synthetic, it resists breakdown better than petroleum-based greases and remains translucent white so it does not stain. You can use it on battery terminals, lawn mower linkage, and paddle boat pedals, as one customer observed, and it repels saltwater. The tube has a fine nozzle that helps apply a tiny amount precisely. This is the grease you pull out for one small job, not the big tub you use for a full bearing repack — the 16 oz Red And Tacky tub above contains 16 oz, whereas this tube is only 0.5 oz.

The obvious catch: at 0.5 oz, you will run out quickly if you try to use it for full axle or suspension work. It is perfect for the repair drawer, but not for a heavy brake job or boat trailer overhaul.

A copper-infused paste that keeps spark plugs and exhaust bolts from fusing to the engine block.

If you have ever snapped a bolt off in an aluminum cylinder head, the memory alone justifies this purchase. The Keze copper anti-seize is a highly refined blend of copper powder, lithium composite, and petroleum distillates that coats threads and mounting surfaces so they never gall or seize, even under extreme heat. It is rated from -30°F to 1800°F, meaning it handles both a frozen winter lug nut and the fiery heat of an exhaust manifold stud.

One buyer called it “the best anti seize lubricant,” using it on “exposed bolts, engine shaft, pto, and pulley bolts” with zero rust issues afterward. At 8 oz, compared to the 16 oz Red And Tacky tub above, but a little goes a very long way on threads. The bottle includes a brush applicator, making it easy to paint onto spark plug threads, lug nuts, oxygen sensor threads, and lawnmower fasteners. Unlike the ceramic brake grease from the same brand, this is for fasteners, not sliding brake components.

The only limitation is that copper anti-seize is electrically conductive, so you must avoid getting it on oxygen sensor tips or any electrical connection. Also, some modern car manufacturers recommend against copper-based compounds on certain fasteners — check your service manual. If you need a non-conductive alternative, the Super Lube silicone grease is a better fit.

A non-curing silicone paste that seals and lubricates O-rings from deep freeze to 500°F.

If you rebuild anything with an O-ring — a pool filter, a vacuum pump, a pneumatic tool — this grease is the right tool. It is a non-curing silicone compound, meaning it stays as a grease and never hardens into a gummy residue. It works across an enormous temperature range of -40°F to 500°F, so it handles both a frosty air compressor in winter and a hot water valve in summer. Because it is registered as an NSF H1 food-grade lubricant, you can also use it on food processing equipment and it is Kosher certified.

Buyers put it to work on wet/dry vac machines, plumbing fittings, and large pool filter O-rings, reporting that it “lasts and is stable without deteriorating rubber.” Unlike petroleum-based greases that cause rubber to swell, silicone grease preserves the elastomer — that is why it is the standard lubricant for the O-rings in your brake caliper and engine vacuum systems. At 14.1 oz in a canister, you get a large supply that is much cheaper per ounce than the small tubes, and one reviewer called it “easier to use than small tubes, and cheaper.”

The honest limitation: this is not a high-load chassis grease. It will not protect a wheel bearing or ball joint — that needs a lithium-based grease like the AtomLube or the Red And Tacky. It also does not have the extreme anti-seize properties of the copper-based Keze compound. This is purely a rubber-and-plastic specialist that does one job perfectly.
