Grease and Lubricants for Bearings, Hinges and Joints
Mobil 1 Synthetic Grease is our top all-round choice for wheel bearings and chassis points thanks to its wide temperature range. Lucas Oil X-Tra Heavy Duty Grease handles high load and water washout, while Super Lube Synthetic Grease with PTFE is the safest pick for household and food-area use.
Mobil 1 Synthetic Grease is the general purpose grease we would keep on the shelf, with Lucas Oil X-Tra Heavy Duty for punishing wet and high load work and Super Lube with PTFE for anything around the house. Between those three, most bearings, hinges, slides and joints are covered.
This category confuses people because the products are not interchangeable even though they look it. Mixing incompatible thickeners can turn two good greases into a runny mess, and a penetrating oil is not a lubricant at all despite living on the same shelf. We ranked these on NLGI grade, thickener chemistry, working temperature range, water washout resistance and the specific applications each is formulated for.
The shortlist, ranked
Mobil 1 Synthetic Grease
Mobil 1 Synthetic Grease is a lithium complex product built on synthetic base oil, which gives it a wider usable temperature range than conventional greases and better resistance to breaking down under repeated heat cycles. It suits wheel bearings, chassis points, universal joints and general automotive work. Owners report it stays in place rather than throwing out of a hub on long hot runs.
Pros
- Handles wide temperature swings well
- Resists oxidation and hardening over time
- Suitable for disc brake wheel bearings
Cons
- Higher outlay than conventional lithium grease
- Overkill for slow speed household hinges
Lucas Oil X-Tra Heavy Duty Grease
Lucas built this grease around tackiness and water washout resistance, which is why it turns up on boat trailers, farm machinery and anything that gets hosed down. It stays put under shock loading rather than being squeezed out of a bearing. Based on specifications it is the pick when the operating environment is wet, dirty or heavily loaded rather than simply hot.
Pros
- Excellent resistance to water washout
- Very tacky so it stays in the bearing
- Handles shock loading well
Cons
- Stringy and messy to apply neatly
- Attracts dirt on exposed pivots
Super Lube 21030 Synthetic Grease with PTFE
Super Lube is a clear, odourless synthetic grease with PTFE particles suspended in it, and it carries an NSF H1 rating for incidental food contact, which makes it the sensible choice for kitchen equipment, garage door tracks and anything indoors. It does not stain, does not smell and will not attack most plastics or rubber. Owners report a small tub lasts for years of household use.
Pros
- Safe around food areas and plastics
- Clear and odourless, does not stain
- One tub covers a huge range of jobs
Cons
- Not intended for high load wheel bearings
- Small tub sizes for the outlay
WD-40 Specialist White Lithium Grease Spray
This is white lithium grease in an aerosol, which solves the problem of getting grease into a hinge, latch or gate mechanism you cannot reach with a finger or a gun. It sprays as a thin liquid, then thickens as the carrier evaporates, so it creeps into the joint before setting. Owners report it is the fastest fix for squeaking door hinges, garage tracks and tailgate latches.
Pros
- Reaches joints a grease gun cannot
- Creeps in then thickens to stay put
- Convenient for occasional jobs
Cons
- Not for high speed or high load bearings
- Overspray needs masking on painted surfaces
Red Line 80401 CV-2 Grease
CV-2 is a synthetic grease with a high dropping point and heavy extreme pressure additives, developed for constant velocity joints, racing wheel bearings and anything that sees sustained heat. It is thicker and more specialised than a general purpose grease. This is what to reach for when a normal grease keeps liquefying and escaping the joint.
Pros
- Stays in place at sustained high temperature
- Strong extreme pressure protection
- Very long service intervals in hard use
Cons
- Specialist product with a specialist outlay
- More than most road cars need
B’laster PB Penetrating Catalyst
PB Blaster is a penetrating catalyst rather than a lubricant, formulated to creep into rusted threads and break the corrosion bond so seized bolts come loose. It belongs in this list because it is the product that has to come out before any grease goes on. Owners report the trick is patience: soak, wait, tap the fastener, and repeat rather than reaching straight for a breaker bar.
Pros
- Genuinely effective on rusted fasteners
- Very widely available and inexpensive
- Works on exhaust bolts and suspension hardware
Cons
- Not a lubricant, offers no lasting protection
- Strong odour and needs ventilation
3-IN-ONE Multi-Purpose Oil
For small hinges, tool pivots, locks, fans and bicycle components, a light mineral oil is often the right answer and grease is simply wrong, because grease attracts dust and gums up fine mechanisms. 3-IN-ONE has done this job for over a century with a precision drip spout that puts oil exactly where it goes. It is the cheapest useful thing in this list.
Pros
- Precise application on small parts
- Does not gum up fine mechanisms
- Very low outlay and long shelf life
Cons
- Washes and drips off exposed parts
- No use at all under load or heat
Before you buy
NLGI grade describes thickness, not quality The NLGI scale runs from 000, which is almost fluid, up to 6, which is block hard. NLGI 2 is the automotive standard and what you want for wheel bearings and chassis fittings. NLGI 0 and 1 suit centralised lubrication systems and cold climates where a stiffer grease will not pump. The grade tells you nothing about how good the grease is, only how stiff it is.
Thickener type decides what you can mix Lithium and lithium complex are the common automotive thickeners and are broadly compatible with each other. Calcium sulphonate, polyurea and clay-based greases often are not, and mixing incompatible thickeners can cause the grease to soften and run out of a bearing. When switching types, clean the old grease out rather than pumping new on top.
Match the product to the failure mode you are fighting If water washes lubricant out, choose the tacky, water resistant option like Lucas X-Tra Heavy Duty. If heat liquefies it, choose a high dropping point synthetic like Red Line CV-2. If dust is the problem, use a light oil rather than any grease. Reaching for the same tub for everything is why joints keep failing.
Penetrants, lubricants and greases do different jobs A penetrating catalyst such as PB Blaster breaks rust bonds and evaporates. A light oil lubricates low load moving parts. A grease holds oil in place under load. Many people use one aerosol for all three and then wonder why the hinge squeaks again next month. Free the part with a penetrant, clean it, then apply the correct grease or oil.

Questions worth asking
Can I mix two different greases?
Only if the thickeners are compatible. Lithium and lithium complex generally mix without problems. Polyurea, calcium sulphonate and clay greases often do not, and an incompatible mix can lose consistency and run out of the bearing. Where you are unsure, purge the old grease out completely before adding new.
What NLGI grade do I need for wheel bearings?
NLGI 2 is the standard for automotive wheel bearings and chassis grease points. In very cold climates NLGI 1 pumps more readily. Always check what the vehicle manufacturer specifies, particularly for disc brake wheel bearings, which need a grease rated for the higher temperatures that brakes generate.
Is WD-40 a lubricant?
The original WD-40 Multi-Use Product is primarily a water displacing penetrant with light lubricating properties, not a long term lubricant. For lasting protection, use the right product for the job: white lithium grease for hinges and latches, silicone for rubber, and proper bearing grease for loaded rotating parts.
Which grease is safe around food?
Look for NSF H1 registration, which covers incidental food contact. Super Lube Synthetic Grease with PTFE carries that rating, which is why it suits kitchen appliances, mixers and food handling equipment. Standard automotive greases should never be used anywhere food might contact them.
How often should I grease chassis fittings?
Follow the manufacturer’s service schedule, which on older vehicles with grease nipples is often every oil change or every few thousand miles. Signs you have left it too long include squeaking over bumps, stiff steering and visible dry or rusty joints. Trailer bearings that get submerged need attention far more often.
Can grease damage rubber or plastic parts?
Some can. Petroleum based greases can swell or degrade certain rubbers and plastics. If you are lubricating a rubber bushing, a plastic gear or a window seal, use a silicone grease or a product explicitly rated as plastic and elastomer safe such as Super Lube.
Does grease go bad in storage?
It can separate over long storage, with oil pooling on top of the thickener. A small amount of separation can be stirred back in. If the grease has hardened, dried out or smells strongly rancid, replace it. Keep tubs sealed and out of direct heat, and most greases last several years.
How do I remove old grease before applying new?
For bearings, wash the old grease out with a solvent-based brake or parts cleaner, then dry completely before packing new grease in. For pivots and joints, wipe out what you can reach and flush the rest. Never leave solvent residue in a bearing, as it thins the new grease.
Our pick
Keep Mobil 1 Synthetic Grease on the shelf as the default for bearings and chassis work, and add Lucas Oil X-Tra Heavy Duty if you run a trailer or anything that lives outdoors in the wet. Super Lube with PTFE covers everything indoors and around food areas, and a can of PB Blaster earns its space long before any of them, because seized fasteners come first.
