6 Greases and Lubricants for Squeak-Free Machinery
Mobil 1 Synthetic Grease covers wheel bearings and chassis points across the widest temperature range. Lucas Oil X-Tra Heavy Duty Grease handles high load and water washout. Super Lube Synthetic Grease with PTFE is the safer pick for household and food area use.
Mobil 1 Synthetic Grease is the general purpose tub worth keeping on the shelf, backed by Lucas Oil X-Tra Heavy Duty for wet, high load work and Super Lube with PTFE for anything around the house. Between those three, most bearings, hinges, slides and joints get covered.
This category confuses people because products that look interchangeable often are not. Mixing incompatible thickeners can turn two good greases into a runny mess, and a penetrating oil is not a lubricant at all despite sitting on the same shelf. We ranked these on NLGI grade, thickener chemistry, working temperature range, water washout resistance and the specific jobs each is built for.
The shortlist, ranked
Mobil 1 Synthetic Grease
This lithium complex grease uses a synthetic base oil, giving it a wider usable temperature range than conventional greases and better resistance to breaking down under repeated heat cycles. Wheel bearings, chassis points, universal joints and general automotive work all suit it. Owners report it stays put rather than flinging 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
- Costs more 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 explains why it shows up on boat trailers, farm machinery and anything that gets hosed down. Shock loading does not squeeze it out of a bearing the way it would a thinner grease. Wet, dirty or heavily loaded environments are where it earns its keep over a simply hot one.
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
Clear and odourless, this synthetic grease suspends PTFE particles and carries an NSF H1 rating for incidental food contact. Kitchen equipment, garage door tracks and anything indoors are natural fits. It will not stain, will not smell, and will not attack most plastics or rubber, and owners report a small tub lasting 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
White lithium grease comes out of this aerosol as a thin liquid, then thickens as the carrier evaporates, letting it creep into a hinge, latch or gate mechanism a finger or grease gun cannot reach. Squeaking door hinges, garage tracks and tailgate latches are the fastest fixes it offers. Owners reach for it first for exactly those occasional jobs.
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
A high dropping point and heavy extreme pressure additives define this synthetic grease, developed for constant velocity joints, racing wheel bearings and anything under sustained heat. It runs thicker and more specialised than a general purpose grease. Reach for it 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 at a specialist price point
- More than most road cars need
B’laster PB Penetrating Catalyst
PB Blaster works as a penetrating catalyst rather than a lubricant, creeping into rusted threads to break the corrosion bond so seized bolts come loose. It belongs on this list because it has to come out before any grease goes on. Patience matters most, since soaking, waiting and tapping the fastener works better 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 needs ventilation
3-IN-ONE Multi-Purpose Oil
Small hinges, tool pivots, locks, fans and bicycle components often need a light mineral oil rather than grease, since grease attracts dust and gums up fine mechanisms. A precision drip spout has put this oil exactly where it belongs for over a century. It is the cheapest useful product on this list.
Pros
- Precise application on small parts
- Does not gum up fine mechanisms
- Very low cost and long shelf life
Cons
- Washes and drips off exposed parts
- No use at all under load or heat
Before you buy
What NLGI grade and thickener type actually mean NLGI grade describes consistency, running from 000, nearly fluid, up to 6, block hard. NLGI 2 is the automotive standard for wheel bearings and chassis points. Lithium and lithium complex thickeners mix safely with each other, but calcium sulphonate, polyurea and clay based greases often do not. Clean old grease out completely rather than pumping new grease on top when switching types.
Best grease for heavy loads and wet conditions Water washing lubricant out of a bearing calls for a tacky, water resistant option like Lucas X-Tra Heavy Duty. Trailer bearings, farm equipment and anything hosed down regularly need that resistance most. Shock loading adds another reason to choose a tackier formulation over a standard lithium grease.
Best grease for high heat and household use Heat that liquefies grease calls for a high dropping point synthetic like Red Line CV-2, built for CV joints and racing bearings. Indoors, food areas and plastics call for a different product entirely, since petroleum greases can swell rubber and stain surfaces. Super Lube with PTFE covers that household side safely.
Penetrants, oils and greases solve different problems A penetrating catalyst such as PB Blaster breaks rust bonds and evaporates rather than lubricating anything long term. A light oil suits low load moving parts, while grease holds oil in place under load. Free a seized part with a penetrant first, 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. Purge the old grease out completely first if you are unsure.
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 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. Squeaking over bumps, stiff steering and visible dry or rusty joints all signal you have left it too long. 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.
Grease vs oil, which do I need for a squeaky hinge?
A light oil like 3-IN-ONE suits most hinges, since grease attracts dust in exposed mechanisms. Reach for grease only where a load bearing joint needs oil held in place under pressure.
Our pick
Mobil 1 Synthetic Grease belongs on the shelf as the default for bearings and chassis work. Add Lucas Oil X-Tra Heavy Duty for a trailer or anything that lives outdoors in the wet. Super Lube with PTFE covers indoor and food area jobs, and a can of PB Blaster earns its space before any of them, since seized fasteners come first.
