Why Differential Servicing Matters

Posted on: June 10th, 2025 by NEAT

Why Differential Servicing Matters – Don’t Skip It!

Your vehicle’s differential is essential for transferring power to the wheels, especially when turning or when grip levels change. In VAG vehicles (particularly those equipped with quattro or Haldex all-wheel-drive systems) the differential works hard behind the scenes to ensure balanced traction, stability, and control in all driving conditions. The differential is the gear train that allows the wheels on a drive axle to rotate at different speeds when cornering. This prevents the wheels from scrubbing or skidding.

Over time, the differential oil begins to degrade. It collects debris and loses its ability to lubricate and protect the internal gears properly. When this happens, you may experience symptoms such as; whining noises, clunky gear engagement, vibration during acceleration, or even full mechanical failure if left unaddressed. Replacing or rebuilding a failed differential can be extremely expensive. Often far more than the cost of routine maintenance.

What is recommended?

That’s why we strongly recommend differential servicing every 40,000 miles or as advised by the manufacturer. The service includes draining the old fluid, inspecting for signs of contamination or metal particles, and refilling with high-quality differential oil suited to your drivetrain. For Haldex-equipped vehicles, changing the fluid and replacing the filter is crucial. Skipping this step can lead to pump failure or issues with AWD engagement. Problems that could have been easily avoided.

Whether your vehicle is stock or tuned, keeping your differential properly serviced helps preserve smooth power delivery. As well as enhancing grip, and protecting against premature wear. It’s a small investment that pays off in performance, reliability, and peace of mind.

Brake Fluid Servicing

Posted on: February 3rd, 2021 by NEAT

Our brake fluid servicing starts at £55 with the option to upgrade to Millers Oils Racing Brake Fluid.

We recommend carrying out a brake fluid service every 2 years, regardless of mileage. This is a preventative measure to ensure the correct running of your vehicle. Brake fluid is hygroscopic, which means it attracts moisture. As you can imagine that does not do your vehicle any favours. With many parts of the braking system being metal. It can lead to corrosion of the metal components if not regularly maintained.

Over time the brake fluid also becomes contaminated with metal particles, reducing the boiling point of the fluid and in turn reducing the braking power of the car.

The upgrade to using Millers Oils is beneficial as the it has a dry boiling point of up to 310 degrees. As opposed to the standard fluid minimum of 230 degrees. This in turn provides exceptional resistance to vapour locking and good compressibility for an improved brake feel. Brake fluids play a key role in driver experience and vehicle feedback. Therefore Millers Oils motorsport brake fluids maintain their viscosity even at high temperature and are robust against water absorption to ensure consistent performance.

Upgrade to Millers Oils for an extra £25.
