Product Information
Full details
The Fuchs Titan Race Syn 5 75W90 is a fully synthetic gear oil designed for high-performance manual transmissions and final drives. Its key benefit is providing optimal power release and 'stay in grade' performance, even in cold conditions, ensuring your drivetrain operates efficiently. A potential caveat is its specific API GL5 rating, meaning it should only be used where this specification is explicitly required.

FAQs
What is the primary benefit of using a fully synthetic gear oil like Syn 5?
Fully synthetic oils offer superior thermal stability, oxidation resistance, and wear protection compared to conventional mineral-based oils. They maintain their performance characteristics over a wider temperature range.
Can I use Fuchs Titan Race Syn 5 in my car if it specifies API GL-4 oil?
It is generally not recommended to use an API GL-5 oil in a gearbox designed for API GL-4, as the extreme pressure additives in GL-5 can sometimes be corrosive to the softer yellow metals (like brass or bronze) used in synchronizer rings of GL-4 specific transmissions. Always refer to your vehicle manufacturer's recommendation.
How often should I change the gear oil in my manual transmission?
Consult your vehicle's owner's manual for the recommended service interval. For performance vehicles or those subjected to hard use (e.g., track days, towing), more frequent changes are advisable.
What does 'stay in grade' performance mean?
'Stay in grade' means the oil maintains its specified viscosity (in this case, 75W90) under extreme operating conditions of heat and pressure, providing consistent lubrication and protection.
Is the 1-litre bottle sufficient for a full gearbox oil change?
The capacity of manual transmissions varies significantly. The 1-litre bottle is convenient for top-ups or for smaller gearboxes. You will need to check your vehicle's specific fluid capacity to determine if multiple bottles are required for a full oil change.
Will using Syn 5 improve my fuel economy?
By reducing internal friction within the drivetrain, lubricants like Syn 5 can contribute to slight improvements in fuel efficiency compared to less advanced or degraded oils. However, this effect is secondary to its primary role of protection.
Troubleshooting
Difficulty shifting gears, especially when cold.
Ensure the correct viscosity (75W90) and specification (API GL-5) have been used. Verify the gearbox has been filled to the correct level. Older transmissions may benefit from a period of use to allow the oil to fully lubricate components.
Gear whine or noise has increased after oil change.
Confirm that the correct API GL-5 specification was used. GL-5 oils contain EP additives that may react differently with certain yellow metals found in older synchronizers or bearings compared to GL-4 oils. Check compatibility with your specific gearbox.
Oil level appears too high or too low after filling.
Re-check the fill procedure. Most manual transmissions are filled to the level of the fill plug hole. Ensure the vehicle is on a level surface during filling and that all excess oil has drained out before replacing the fill plug.
Pros and Cons
Pros
Excellent low-temperature fluidity for smooth shifting.
Superior protection against wear in high-stress applications.
Maintains performance consistency across a wide temperature range.
Contributes to drivetrain efficiency by reducing friction.
Cons
Specific API GL5 rating may not be suitable for all vehicle applications.
Fully synthetic formulation may be priced higher than conventional alternatives.
Requires careful application to ensure compatibility with specific gearbox materials.
Setup, Compatibility & Care
Compatibility:
Primary Use: Recommended for manual transmissions and final drives that explicitly require an API GL-5 specification lubricant.
Viscosity: Suitable for vehicles specifying a SAE 75W90 gear oil.
Verification: Always consult your vehicle's owner's manual or manufacturer's specifications to confirm the correct lubricant type and viscosity grade before use.
Setup/Application:
Ensure the vehicle's drivetrain components (gearbox, differential) are at ambient temperature before draining.
Drain the old lubricant completely.
Refill with the new Fuchs Titan Race Syn 5 to the manufacturer-recommended level, typically indicated by a fill plug.
Use appropriate sealing methods for drain and fill plugs as per vehicle manufacturer guidelines.
Care:
Storage: Store the 1-litre bottle in a cool, dry place, away from direct sunlight and extreme temperatures. Keep the cap tightly sealed.
Fluid Changes: Adhere to the manufacturer's recommended intervals for gear oil changes. Performance driving may necessitate more frequent changes.
