Best Lubricants by Application and Business Type

Best engine oil for fleets and performance shops

Mobil 1 C40 GT 0W-40 offers wide temperature protection for mixed-duty fleets and dealer prep, while Mobil 1 0W-40 Supercar supports high output engines with strong film strength and clean operation for performance service.

Best EP grease for construction and material handling

Molykote BR2 Plus EP Grease maintains a protective film under shock loads on bearings, bushings, and pivot points, which makes it a reliable choice for loaders, forklifts, and plant equipment.

Best assembly paste for manufacturing and fabrication

Molykote G-N Plus Metal Assembly Paste improves torque consistency and resists fretting on press fits, splines, and threaded joints, which helps reduce rework and eases disassembly on production lines.

Best chain lubricant for transportation and powersports

Chain Lube with Shockproof forms a tacky, water resistant film that reduces fling and corrosion on drive chains, which is ideal for logistics fleets, motorcycles, and off-road vehicles.

Best insulating compound for utilities and instrumentation

Molykote 4 Electrical Insulating Compound provides a moisture barrier and dielectric protection on connectors and gaskets, which supports reliable operation for telecom, utility, and marine applications.

Best corrosion protection for marine, storage, and outdoor assets

Boeshield T-9 leaves a protective film that displaces moisture and helps prevent rust on tools, fixtures, and equipment in damp or salt-air environments.

Best hydraulic fluid for shop service and mobile equipment

PresurFlo ISO 46 Hydraulic Fluid balances cold start flow with film strength under heat and load, which is well suited for lifts, presses, and off-road hydraulics.

FAQ

What is the difference between grease, paste, and assembly lube

Grease suspends oil in a thickener for long stay lubrication on bearings and pivot points. Paste contains solids for boundary protection in high load and low speed conditions. Assembly lube protects fresh builds during initial startup when oil flow has not yet stabilized.

Can one 0W-40 cover both fleet and performance needs

Yes. Premium synthetics such as Mobil 1 0W-40 Supercar handle cold starts and high temperature operation, which makes them practical for dealer prep, mixed fleets, and performance builds where the spec allows.

When should I choose an EP grease over a standard multipurpose grease

Use an EP grease like Molykote BR2 Plus when equipment sees shock loads, contamination, or heavy duty cycles such as loader arms, pivot pins, and industrial bearings.

Where does an assembly paste make the biggest difference

Assembly pastes such as Molykote G-N Plus help on splines, press fits, and fasteners that require controlled torque and predictable disassembly during service.

How do I choose a chain lubricant for mixed weather use

Look for a chain lube that resists water washout and stays tacky, such as Chain Lube with Shockproof, to reduce fling and keep corrosion at bay in wet conditions.

What products help with electrical moisture protection

A silicone dielectric compound such as Molykote 4 creates a water resistant barrier on connectors, terminations, and gaskets without curing hard.

How should bulk lubricants be stored

Keep sealed containers in a cool, dry place away from sunlight. Rotate stock by date code, keep lids clean, and avoid mixing different chemistries in open containers.

Why buy lubricants by the case or pallet

Multipacks reduce cost per unit, standardize chemistries across teams, and ensure availability for service intervals, which cuts downtime and simplifies procurement.
