Product Information

Full details

This guide is for automotive enthusiasts and mechanics seeking to enhance manual transmission performance and longevity. Driven Racing Oil STF offers superior protection against extreme heat, friction, and wear, leading to improved gear shifting and lower operating temperatures. A key consideration is that it is a specialized fluid, not a universal replacement for all transmission types.

FAQs

What vehicles is Driven Racing Oil STF designed for?

It is designed for manual transmissions in vehicles from GM, Chrysler, Honda, and Mini Cooper, particularly those requiring ATF, multi-viscosity, or straight-grade motor oil specifications, and where high heat protection is needed.

Can I use this fluid in an automatic transmission?

No, this product is specifically formulated for manual transmissions and synchronized gearboxes. It is not intended for use in automatic transmissions.

How often should I change my transmission fluid?

Consult your vehicle's owner's manual for the recommended service interval. For performance or severe driving conditions, more frequent changes may be beneficial.

What does 'yellow metal compatibility' mean?

It means the fluid is formulated to be safe for components made of brass, bronze, and other 'yellow metals' commonly found in manual transmission synchronizers and other parts.

How does STF reduce operating temperatures?

By reducing friction between moving parts, less energy is converted into heat, thus lowering the overall operating temperature of the transmission.

What is the viscosity of this fluid?

Driven Racing Oil STF is designed to meet various viscosity requirements and is compatible with fluids specified as multi-viscosity or straight grade. Refer to your vehicle's manual for specific viscosity needs.

Where can I purchase Driven Racing Oil STF?

This product is available through authorized Driven Racing Oil dealers and select online automotive parts retailers.

Troubleshooting

Difficulty shifting gears after fluid change

Verify the correct fluid type was used and that the transmission was filled to the proper level. Ensure no air pockets remain.

Transmission fluid leaks

Check that the drain plug and fill plug are properly tightened. Inspect seals and gaskets for damage.

Increased transmission noise

Ensure the correct fluid viscosity was chosen for the application. Check for any internal transmission component wear, as fluid alone cannot fix mechanical damage.

Fluid appears contaminated

This may indicate internal transmission wear or seal failure. Consider a full transmission inspection and flush.

  • Availability may be limited compared to conventional fluids

Setup, Compatibility & Care

Compatibility:

  • Verify your vehicle's service manual to confirm if your manual transmission is designed to accept Automatic Transmission Fluid (ATF), multi-viscosity, or straight-grade motor oil specifications. This fluid is specifically formulated for *manual* transmissions.
  • Ensure compatibility with synchronized transmissions and associated components, including yellow metals.
  • Exceeds requirements for GM, Chrysler, Honda, and Mini Cooper synchronized transmissions.

**Setup (Fluid Change):

  1. Ensure the transmission is at a moderate operating temperature (not hot).
  2. Locate and remove the transmission drain plug.
  3. Allow all old fluid to drain completely.
  4. Reinstall the drain plug securely.
  5. Locate and remove the transmission fill plug.
  6. Using a fluid pump, fill the transmission with Driven Racing Oil STF until the fluid level reaches the bottom of the fill hole.
  7. Reinstall the fill plug securely.
  8. Dispose of old fluid responsibly.

Care:

  • Store the fluid in a cool, dry place away from direct sunlight.
  • Keep the container tightly sealed when not in use to prevent contamination.
  • Regularly check transmission fluid levels and condition as per your vehicle manufacturer's recommendations.
