What is a Mileage Blocker?

A Mileage Blocker is a device designed to stop the odometer from recording mileage during vehicle testing. This tool ensures that no additional mileage is logged while performing diagnostics, making it essential for accurate testing without affecting the car's recorded mileage.

How does a Mileage Blocker work?

A Mileage Blocker works by temporarily interrupting the signal between the vehicle's speed sensors and the odometer, effectively freezing the mileage count. This allows you to conduct performance tests without adding extra miles to the odometer.

Is the Mileage Blocker easy to install?

Yes, Mileage Blockers are designed for easy installation. They feature a plug-and-play system that requires no special tools or technical expertise, allowing you to install the device in minutes.

Can a Mileage Blocker be detected during a vehicle inspection?

No, a properly installed Mileage Blocker is undetectable during routine vehicle inspections. It operates without leaving any traces, ensuring that the vehicle's original mileage remains unaffected.

Is the Mileage Blocker compatible with all vehicle models?

Mileage Blockers from Dynotest are compatible with a wide range of vehicle models. We offer specific versions of the device tailored to different car brands and models, ensuring seamless integration with your vehicle's electronics.

Why should I use a Mileage Blocker during vehicle testing?

Using a Mileage Blocker during vehicle testing prevents unnecessary mileage from being added to your car. This is crucial for maintaining accurate mileage records, especially for professionals in the automotive industry who require precise data for diagnostics and performance tuning.

Will using a Mileage Blocker affect my car’s performance?

No, using a Mileage Blocker will not affect your car’s performance. The device only pauses the odometer, ensuring that no mileage is recorded during tests without interfering with the vehicle’s functionality.

Can I use the Mileage Blocker for long-term use?

Mileage Blockers are intended for temporary use during specific testing and diagnostic procedures. It is important to deactivate the device after testing to resume normal mileage recording.

Do Mileage Blockers comply with legal regulations?

The legality of Mileage Blockers varies by jurisdiction. They are typically intended for off-road testing and diagnostics only. It is essential to check local laws and regulations before using the device on public roads.
