Product Information

Full details

Liqui Moly Classic Transmission Oil SAE 90 is a mineral-based lubricant for manual transmissions in classic vehicles and motorcycles. It offers reliable lubrication, minimizes wear, and ensures smooth gear shifts, providing long-term protection for vintage drivetrains. While ideal for older vehicles, its specific mineral base may not be suitable for all modern transmissions requiring synthetic fluids.

FAQs

Is this oil suitable for all classic cars?

It is designed for manual transmissions in classic vehicles and motorcycles, but you must verify that your specific vehicle's manual recommends an SAE 90 mineral-based transmission oil. Always consult your owner's manual or a specialist.

Can I use this in a modern car with a manual transmission?

Generally, no. Modern transmissions often require synthetic oils with different additive packages. Using this mineral-based oil in a vehicle that specifies synthetic could lead to poor performance or damage. Always refer to your vehicle's specifications.

What does SAE 90 mean?

SAE 90 refers to the viscosity grade of the oil according to the Society of Automotive Engineers (SAE) standards. It indicates a specific thickness and flow rate suitable for certain operating temperatures and gearboxes.

How often should I change my transmission oil?

Refer to your vehicle's service manual for the recommended interval. For classic vehicles, a common interval is every 30,000 to 50,000 miles, or every few years, depending on usage and manufacturer recommendations.

Will this oil protect against rust if my classic car is stored for long periods?

Yes, the corrosion protection additives in this oil are formulated to help protect internal transmission components from rust and corrosion, even during storage periods when moisture can be a factor.

How much oil do I need for a standard manual transmission?

The exact amount varies by vehicle. Typically, manual transmissions hold between 1.5 to 3 liters (quarts). Consult your vehicle's owner's manual for the precise capacity.

Troubleshooting

Difficulty shifting gears, especially when cold.

Ensure the correct SAE viscosity and oil type (mineral-based SAE 90) are used. Verify the transmission is filled to the correct level. Cold weather can naturally make shifting stiffer; this oil is designed to mitigate that, but extreme cold may still have an effect.

Transmission noise (whining or grinding).

Check the oil level; low oil can cause noise. If the noise persists after confirming the correct oil level and type, it may indicate internal wear or damage that requires professional inspection.

Oil leak from transmission seals.

This oil is not typically a cause of leaks unless overfilled. If leaks occur, it is likely due to degraded or damaged seals, which should be replaced by a qualified mechanic.

Pros and Cons

Pros

  • Provides excellent lubrication for manual transmissions in classic vehicles.
  • Offers robust protection against rust and corrosion.
  • Contributes to smoother gear shifting.
  • Helps to minimize wear on critical transmission components.
  • Specifically formulated for the demands of older vehicles.

Cons

  • Not suitable for modern transmissions that require synthetic oil.
  • Mineral-based formula may not offer the same extreme temperature performance as synthetics.
  • Requires checking vehicle compatibility before use.

Setup, Compatibility & Care

Compatibility:

This transmission oil is specifically formulated for manual transmissions in classic vehicles and motorcycles. Always consult your vehicle's owner's manual or a qualified mechanic to confirm that an SAE 90 mineral-based transmission oil is the correct specification for your specific make and model. It is generally not recommended for modern transmissions that specify synthetic or lower viscosity fluids.

Setup (Oil Change Procedure):

  1. Ensure the transmission is at operating temperature for easier draining. Safely lift the vehicle to access the drain plug.
  2. Locate and remove the transmission drain plug. Allow the old oil to drain completely.
  3. Clean and reinstall the drain plug with a new washer if required.
  4. Locate and remove the fill plug.
  5. Using a pump or funnel, fill the transmission with the correct amount of Liqui Moly Classic Transmission Oil SAE 90 until it reaches the bottom of the fill plug hole. The required quantity is typically specified in your vehicle's manual.
  6. Clean and reinstall the fill plug.
  7. Lower the vehicle and dispose of the old oil responsibly.

Care:

Store the oil in a cool, dry place, away from direct sunlight and extreme temperatures. Keep the container tightly sealed to prevent contamination. Regular transmission fluid checks and changes, as recommended by your vehicle manufacturer, are crucial for maintaining transmission health.
