Specification: API GL5
Application: Compatible manual transmissions, transaxles and final drives without limited-slip differentials

What Does Fully Synthetic Gear Oil GL5 75W-90 Do?

Gear oil lubricates and protects the moving components inside manual transmissions, transaxles and differential assemblies.

These components operate under significant mechanical pressure and rely on the correct lubricant to reduce friction, control wear and maintain smooth operation.

LIQUI MOLY Fully Synthetic Gear Oil SAE 75W-90 is designed to:

• Lubricate gears, shafts, bearings and other moving components
• Provide excellent protection against wear
• Maintain a strong lubricating film under high mechanical loads
• Reduce friction and gearshift resistance
• Help minimise transmission noise
• Protect internal components against corrosion
• Maintain stable viscosity across changing temperatures
• Resist oxidation and premature ageing
• Support reliable operation under demanding driving conditions

Its fully synthetic formulation helps maintain consistent lubrication even when exposed to substantial temperature fluctuations.

Why Is High-Quality Gear Oil Important?

Manual gearboxes, transaxles and final drives rely on the correct lubricant to protect their internal components and maintain reliable operation.

Gear teeth and bearings are subjected to repeated mechanical loading, particularly during acceleration, deceleration and high-speed driving.

Using an unsuitable or deteriorated lubricant can contribute to increased friction, gear wear, transmission noise and difficult gear changes.

LIQUI MOLY Fully Synthetic Gear Oil GL5 75W-90 is formulated to provide excellent high-pressure protection and stable friction characteristics in compatible transmissions.

Why Choose Fully Synthetic SAE 75W-90 Gear Oil?

Fully synthetic gear oils offer excellent temperature stability and resistance to ageing compared with conventional mineral-based lubricants.

The SAE 75W-90 viscosity grade provides effective lubrication across a broad operating temperature range.

Benefits include:

• Reliable lubrication during cold starts
• Excellent protection at high operating temperatures
• Strong resistance to mechanical stress
• Consistent viscosity characteristics
• Reduced transmission noise
• Smooth gearshift operation in compatible gearboxes
• Excellent long-term wear protection

The correct viscosity and specification must always be selected according to the vehicle or transmission manufacturer's requirements.

Why Does Gear Oil Deteriorate?

Transmission and differential oils are exposed to heat, pressure and repeated mechanical loading throughout their service life.

Over time, these conditions can reduce the lubricant's protective properties.

Common causes of deterioration include:

• Prolonged exposure to high operating temperatures
• Oxidation and ageing of the oil
• Contamination from normal gear and bearing wear
• Heavy driving loads and repeated acceleration
• Moisture entering the transmission housing
• Incorrect oil levels Extended service intervals
• Use of an unsuitable lubricant specification

Deteriorated gear oil can contribute to increased noise, difficult gear changes and premature wear of internal transmission components.

When Should Gear Oil Be Replaced?

Gear oil should be replaced according to the vehicle or transmission manufacturer's recommended service schedule.

The appropriate interval depends on the gearbox design, operating conditions and vehicle usage.

A transmission or differential inspection may be required if the vehicle develops:

• Increased gearbox or final-drive noise
• Difficult or notchy gear changes
• Unusual whining or rumbling sounds
• Visible transmission oil leaks
• Contaminated or degraded lubricant
• Excessive metallic particles in the drained oil
• A scheduled gearbox or differential service

These symptoms may also indicate mechanical wear or other faults, so replacing the lubricant alone may not resolve the problem.

Porsche Manual Gearbox & Transaxle Applications

LIQUI MOLY Fully Synthetic Gear Oil GL5 SAE 75W-90 may be suitable for selected Porsche manual gearbox, transaxle or final-drive applications where the manufacturer specifies an API GL5 SAE 75W-90 lubricant.

However, transmission lubricant requirements vary considerably between models and gearbox generations.

This product must not be assumed suitable for every Porsche manual transmission, differential or transaxle.

In particular, some synchronised manual gearboxes require specific friction characteristics or lubricant approvals that differ from conventional API GL5 gear oils.

Always confirm the correct oil specification using the Porsche workshop information or the relevant gearbox manufacturer's recommendations.

This product is intended for compatible assemblies without limited-slip differentials. Where a limited-slip differential requires a dedicated LS lubricant, a suitable limited-slip gear oil should be selected instead.

Application & Service Instructions

Always follow the vehicle or transmission manufacturer's instructions regarding the correct oil specification, filling quantity and service interval.

Drain the existing gear oil using the recommended service procedure and inspect the old lubricant for signs of contamination or excessive wear.

LIQUI MOLY confirms that this product is miscible with residual mineral-based oil remaining in transmissions and axle drives during an oil change.

However, the correct lubricant specification must still be observed.

Fill the transmission or differential to the manufacturer's specified level and inspect for leaks following servicing.

Dispose of used gear oil responsibly through an approved waste oil collection facility.

MoS2 forms a highly resistant lubricating film across rubbing and sliding metal surfaces inside the engine. Combined with the 10W-40 semi-synthetic base oil, this provides rapid lubrication during cold starts and helps reduce friction once the engine reaches operating temperature

What Does MoS2 Leichtlauf 10W-40 Do?

Engine oil creates a lubricating film between moving components, reducing direct metal-to-metal contact and helping control friction, heat and wear.

LIQUI MOLY adds MoS2 solid lubricant to provide an additional high-load lubricating film on internal friction surfaces. This is particularly beneficial during starting and warm-up, under heavy engine loads and in stop-start driving conditions.

The formulation is designed to provide:

• Excellent protection against wear
• Rapid lubrication after a cold start
• Reduced internal friction
• Good cold-start behaviour
• Excellent engine cleanliness
• Stable viscosity
• Good resistance to ageing
• Excellent emergency-running properties
• Reduced oil and fuel consumption

LIQUI MOLY describes the oil as a special development combining low-friction engine oil technology with the additional protection of MoS2 solid lubricant.

Why Use MoS2 Engine Oil?

Molybdenum disulphide is a solid lubricant that forms a protective lubricating film on metal surfaces. This provides an additional layer of protection alongside the conventional oil film.

This makes MoS2 Leichtlauf particularly suitable for engines where reducing friction and protecting heavily loaded internal components are priorities.

The oil can be used in petrol and diesel engines and has been tested for both turbocharger and catalytic converter compatibility. LIQUI MOLY particularly recommends it for vehicles without a diesel particulate filter.

Its formulation provides a stable lubricating film even under demanding operating conditions, with an increased proportion of wear-protection components. It also offers strong cleaning and dispersing properties to help prevent sludge formation and keep contaminants suspended within the oil.

What Does Touring High Tech HD 30 Do?

Touring High Tech HD 30 lubricates and protects the internal moving components of older petrol and diesel engines where an SAE 30 single-grade oil is specified.

Unlike a multigrade oil such as 20W-50, SAE 30 has a single viscosity classification. This makes it particularly relevant to classic engines and mechanical assemblies originally designed to operate with a straight-grade lubricant.

LIQUI MOLY states that the oil provides high wear resistance, excellent cleaning, good ageing stability, high shear stability and reliable lubrication.

Why Choose Touring High Tech HD 30?

This oil is particularly useful where the engine or equipment manufacturer specifically calls for a mildly blended SAE 30 lubricant.

Key benefits include:

• Mineral-based formulation
• SAE 30 single-grade viscosity
• High wear resistance
• Stable lubricating film under demanding conditions
• Helps prevent sludge formation
• Excellent cleaning properties
• Very good dispersing properties
• High shear stability
• Good ageing stability
• Suitable for petrol and diesel engines
• Suitable for naturally aspirated and turbocharged applications
• Tested for catalytic converter compatibility

LIQUI MOLY describes Touring High Tech HD 30 as particularly suitable for older vehicles and assemblies and confirms compatibility with turbochargers.

How Does LIQUI MOLY Touring High Tech HD 30 Differ?

LIQUI MOLY Touring High Tech HD 30. It is a SAE 30 mineral single-grade oil. It carries ACEA E2 and API SJ/CF/CF-4 specifications and is designed for classic engines and older assemblies requiring a mildly blended straight-grade oil.

LIQUI MOLY MoS2 Low-Friction 20W-50. It is a mineral-based multigrade oil containing molybdenum disulphide (MoS2) solid lubricant. It is intended for petrol and diesel engines, including turbocharged engines, particularly under demanding operating conditions. LIQUI MOLY recommends it for ACEA A3/B4 and API SL applications.

LIQUI MOLY Classic Motoroil SAE 20W-50 HD. This is also a mineral multigrade oil, but unlike MoS2 Low-Friction 20W-50 it is specifically formulated as a mildly blended classic vehicle oil rather than an MoS2 friction-reducing formulation. It is designed for classic cars and motorcycles with oil .

In simple terms:

• SAE 30 single-grade mineral oil for older engines and assemblies specifically requiring SAE 30.
• SAE 20W-50 mineral multigrade with MoS2 solid lubricant, aimed at strong wear protection under demanding conditions.
• SAE 20W-50 mineral multigrade specifically formulated for classic engines with an oil filter.

They should not be treated as interchangeable purely because they are mineral-based oils. The correct choice depends on the viscosity and specification required by the engine manufacturer.

Suitable Applications

LIQUI MOLY specifies Touring High Tech HD 30 for petrol and diesel engines and particularly for older vehicles and assemblies. It can also be used in turbocharged applications where the required oil specification matches.

For classic Porsche applications, always check the engine manufacturer's required viscosity and specification. An SAE 30 straight-grade oil should only be selected where this viscosity is appropriate for the particular engine and operating conditions.

Classic Porsche SAE 30 Mineral Engine Oils

Single-grade mineral engine oils remain relevant for classic vehicles and older mechanical assemblies originally designed around traditional lubricant specifications.

LIQUI MOLY Touring High Tech HD 30 combines an SAE 30 viscosity with modern additive technology while retaining the mineral-based, mildly blended formulation required by certain older engines. Its cleaning and dispersing properties help combat sludge formation, while increased wear-protection components help maintain a reliable lubricating film under demanding operating conditions.
