MG Mileage Blocker – Features, Benefits, and Responsible Use

Whether you’re testing or tuning your MG vehicle, it’s essential to prevent unnecessary mileage from being recorded during diagnostics. A mileage blocker is the safest and most effective tool for the job. It’s designed to pause mileage tracking in real time — ideal for workshops, off-road environments, or controlled test sessions.

In this guide, we’ll explain how the MG mileage blocker works, when you should use it, and why it’s a superior alternative to odometer rollback tools.

What Is an MG Mileage Blocker?

The MG mileage blocker (also known as a kilometre stopper) is a plug-and-play device that prevents your car from recording distance travelled while active. Unlike odometer correction tools — which attempt to roll back mileage already stored — this device simply stops new mileage from being logged across all electronic control units (ECUs).

It leaves no digital trace when used properly and is built for ethical, legal use in non-public environments.

When Should You Use It?

This tool is designed for responsible use during:

• Post-service diagnostics

• Dyno or emissions testing

• Performance tuning

• ECU programming and calibration

• Workshop-based test drives

⚠️ Note: Using a mileage blocker on public roads or for resale manipulation is illegal. It’s intended solely for off-road or private use.

Key Features of the MG Mileage Blocker

• Stops mileage across all control units
  This device prevents mileage from being stored in any ECU — not just on the dashboard. Even advanced diagnostics tools won’t detect any distance travelled during use.

• App-based control with SKF Speed
  Easily activate or deactivate the blocker in real time using the SKF Speed App, available for iOS and Android devices.

• Fast, plug-and-play installation
  No wire cutting or special tools needed. Installs in under an hour using your MG’s original connectors.

• Tailored to MG models
  The blocker is built to work seamlessly with specific MG vehicles, such as the MG ZS, MG4, MG5, and MG HS, ensuring reliable performance.

• Control while in motion
  Activate the blocker while driving via your steering wheel buttons or directly through the app.

Why Choose a Mileage Blocker Over Odometer Rollback?

Odometer correction tools come with major drawbacks:

• They only change the dashboard reading — ECU mileage remains intact and detectable

• Improper use may cause system errors or permanent damage

• Using them for resale manipulation is illegal and punishable by law

The MG mileage blocker is non-invasive, safe, and offers a clean way to pause mileage — without changing historical data or compromising your vehicle’s systems.

Final Thoughts

The MG mileage blocker is a smart, safe, and legal solution for mileage control during diagnostics and off-road testing. Whether you’re servicing an MG ZS EV or tuning an MG4, this device offers full control over mileage tracking — with zero trace left behind.

Just remember: always use this tool ethically and within the bounds of the law.
