What Grease Should I Use for My Car? - Types, Uses and Advice

Grease is a complex blend of base oils, thickeners and performance additives. Because of this, there is no single product that works for every job on a vehicle. Understanding car grease types explained is essential if you want to avoid premature wear or component damage.

Modern vehicles (especially those with higher temperatures, tighter tolerances and advanced braking systems) make choosing the correct grease more important than ever in 2026.

Mythbusting: what is multipurpose grease?

Multipurpose grease is widely sold, but it is often misunderstood. Despite the name, it is not suitable for every automotive application.

What is multipurpose grease used for?

In general, multipurpose grease is best for light-duty, low-stress areas such as:

• Door latches and hinges
• Locks and hinges
• Tow balls (light lubrication only)
• Basic mechanical joints with low heat exposure

It is often used because it is convenient, not because it is always correct.

Limitations of multipurpose grease

Multipurpose grease can vary significantly in quality:

• Some use basic soap thickeners with minimal additives
• Others use more advanced lithium-based formulations
• Performance at high temperature can be inconsistent

Because of this variation, assuming it works everywhere can cause issues in modern vehicles.

When a specialist grease is better

In many cases, a dedicated product is safer and more effective:

• Wheel bearings → high-load, high-temperature grease
• Brakes → specific brake-safe lubricants
• Electrical connectors → dielectric products

For example, complex lithium or calcium-based products may be better suited for wheel bearings, especially where water resistance matters.

What is copper grease used for in cars?

Copper grease is an anti-seize compound rather than a true lubricant.

Typical copper grease uses include:

• Exhaust bolts and high-temperature fasteners
• Metal-to-metal non-moving joints
• Areas requiring future disassembly

However, there are important limitations:

• It is not suitable for rubber components
• It can interfere with ABS wheel speed sensors
• It should NOT be used on modern braking friction surfaces

For braking systems, modern workshops increasingly prefer dedicated brake grease types or ceramic alternatives instead.

If you’re unsure, our guide on brake servicing explains where lubrication is and isn’t appropriate.

What is ceramic grease?

Ceramic grease is a modern alternative to copper grease.

Key benefits:

• High-temperature resistance
• Non-metallic (safe for sensors and electronics)
• Suitable for braking system components

In 2026, ceramic compounds are increasingly preferred in workshops due to compatibility with ABS and stability systems.

What is silicone grease?

Silicone grease is made from silicone oil and a thickener.

It is commonly used as silicone grease for cars in:

• Rubber seals and O-rings
• Sliding caliper components (non-friction areas)
• Plastic-to-metal interfaces

It is not suitable for high-load bearings or metal-on-metal heavy stress applications.

What is dielectric grease?

Dielectric grease is designed specifically for electrical systems:

• Protects connectors from moisture and corrosion
• Prevents oxidation on terminals
• Does not conduct electricity

It is widely used in modern vehicles with increasing electronic complexity.

What are EP greases (extreme pressure)?

EP (extreme pressure) greases contain additives such as molybdenum disulphide.

Typical EP grease applications include:

• CV joints
• High-load sliding mechanisms
• Shock-loaded mechanical joints

However:

• Not ideal for very high temperatures
• Not suitable for exposed wet environments in many cases

What is rubber grease?

Rubber grease is designed for compatibility with rubber components:

• Suspension bushes
• Brake assembly rubber parts
• Seals and grommets during installation

It is often used as an assembly lubricant to prevent tearing or binding.

What are PTFE or white greases?

White greases typically use calcium-based thickeners and PTFE additives:

• Good water resistance
• Long-lasting lubrication film
• Ideal for locks, hinges and light mechanisms

Can I mix different types of grease?

Mixing greases is generally not recommended.

Risks include:

• Breakdown of thickener structure
• Reduced lubrication performance
• Chemical incompatibility between additives

In modern vehicles, mixing different products can also lead to contamination of sealed systems such as wheel bearings or braking components.

As a rule:

• Stick to one specified grease type per application
• Clean old grease before applying new product
• Follow manufacturer guidance

What happens if I use the wrong grease?

Using the wrong grease can cause serious issues:

• Premature wear of components
• Brake contamination or reduced braking performance
• Swelling or degradation of rubber parts
• Electrical faults in sensitive systems

For example:

• Copper grease on ABS-related components may cause sensor issues
• General multipurpose grease in wheel bearings may fail under heat
• Wrong grease in seals can cause leaks or sticking

Choosing correctly is a key part of modern vehicle maintenance and an important part of any automotive grease guide.

Where NOT to use grease

Some areas of a vehicle should never be lubricated unless specifically specified:

• Brake friction surfaces (pads/discs)
• Tyres or tyre bead contact areas
• ABS sensors or wheel speed rings
• Engine combustion components
• Electrical fuse contacts (unless dielectric grease is specified)

Incorrect application can compromise safety systems and braking performance.
