Always check the required Porsche gearbox oil specification and viscosity for the individual model before ordering.
Its special limited-slip additives help reduce friction and prevent stick-slip behaviour, while maintaining a stable lubricating film under demanding operating conditions.
The SAE 85W-90 formulation provides reliable wear protection and lubrication across varying operating temperatures.
What Does It Do?
This gear oil lubricates and protects gears, bearings and differential components, reducing friction and wear while supporting smooth operation of compatible limited-slip differentials.
Why Does Gear Oil Deteriorate?
Common causes include:
- High operating temperatures
- Heavy mechanical loading
- Contamination from internal wear
- Moisture ingress Extended service intervals
When Should It Be Replaced?
Replace according to the vehicle manufacturer's service schedule or when the lubricant becomes contaminated or degraded. Unusual differential noise or limited-slip chatter may indicate a need for inspection.
Specifications & Recommendations
- API GL5
- MIL-L 2105 D
- GM B 40 1010
- Volvo 97311
- ZF TE-ML 05C / 21C
- DAF
The latter manufacturer specifications are LIQUI MOLY recommendations rather than formal approvals.
Porsche Compatibility & Installation
Suitable for Porsche differential or axle-drive applications only where the manufacturer specifies a compatible GL5 LS SAE 85W-90 lubricant.
Always confirm the correct specification, filling quantity and service interval before use. This oil is not a universal replacement for Porsche manual gearbox or PDK transmission fluids.
LIQUI MOLY Limited-Slip Differential Oils & Gear Lubricants
LIQUI MOLY Hypoid Gear Oil GL5 LS SAE 85W-90 is formulated for high-load axle drives with or without limited-slip differentials, particularly where LS additives are required.
Its mineral-based formulation provides reliable lubrication, excellent wear protection and reduced friction under demanding conditions.
