What Is a Reduction Gear Oil Service

This service involves draining the old oil from the reduction gearbox and replacing it with fresh, high quality oil designed to protect and lubricate the internal gears.

As oil ages, it loses its effectiveness. Replacing it at the right interval helps maintain smooth operation, reduces internal friction, and supports the long term health of the drivetrain.

During this process, it is common to find fine metal particles within the old oil. This is a natural result of wear over time. If left unchanged, these particles continue to circulate through the system, increasing wear and potentially leading to more serious mechanical issues.

When Should It Be Done?

As a general guideline, we recommend replacing the reduction gear oil every 40,000 miles.

Waiting until you notice noise or vibration from the drivetrain can often mean damage has already started to occur. Carrying out this service proactively is a cost effective way to avoid more significant repairs later on.

If your vehicle has not had this service before, it is well worth adding it to your maintenance schedule – get a free quote today.

Why This Service Is Important

Regular reduction gear oil servicing helps to:

  • Protect internal components from premature wear
  • Support efficient power delivery
  • Reduce the risk of drivetrain noise or vibration
  • Identify early signs of potential issues
  • Maintain long term reliability

This is a simple but highly effective way to protect some of the most expensive components in your electric vehicle.
