Extended Product Information

FAQs

Is this oil compatible with manual transmissions?

It is designed for gear and axle use; check your owner's manual to confirm if your manual transmission requires an API GL-5 lubricant.

Can I mix this with other gear oils?

It is generally recommended to avoid mixing different oil brands or specifications to maintain the integrity of the additive package.

Does this meet Volkswagen standards?

Yes, it is recommended by Granville for VW specifications G 052 190 and G 052 518.

What does GL-5 mean?

GL-5 is an API service classification for gear lubricants designed for high-speed/shock-load and low-speed/high-torque conditions.

How often should I change this oil?

Always follow the service intervals specified in your vehicle's maintenance manual rather than a set mileage for the oil itself.

Is this product synthetic or mineral-based?

Granville EP 75W/85 is a fully synthetic lubricant.

Troubleshooting

Increased gear noise after oil change

Verify the fill level is correct according to the manufacturer specifications and check that the oil grade matches your vehicle requirements.

Difficulty shifting gears

Ensure the oil is appropriate for the transmission type; some synchronizers require specific viscosity or friction modifiers not found in all GL-5 oils.

Pros and Cons

Pros

  • Excellent protection under high shock and load
  • Effective at managing component heat build-up
  • Meets rigorous international OEM standards
  • Suitable for high-speed and high-torque applications

Cons

  • Not suitable for transmissions requiring non-GL-5 oils
  • Requires professional handling to avoid environmental contamination
  • Must be checked against specific vehicle manual for exact fitment

Setup, Compatibility & Care

Before changing your gear oil, consult your vehicle's service manual to confirm the required oil specification. This fluid is compatible with systems requesting API GL-5. Ensure the vehicle is on a level surface and the drivetrain is at a manageable temperature. When performing the change, use a clean pump or funnel to fill the transmission or differential until it reaches the fill-plug level. Always dispose of used oil at an authorized recycling facility. Keep containers sealed tightly in a cool, dry place to prevent moisture contamination.
