Frequently Asked Questions — Mileage Blocker USA
Everything you need to know about mileage blockers, CAN-Bus filters and our products. Can’t find your answer? WhatsApp us 24/7 →
Do mileage blockers really work?
Yes. A quality vehicle-specific mileage blocker from Mileage Blocker USA works by intercepting the speed signal at the CAN-Bus level before it reaches any of your vehicle’s modules. Zero miles are added to your odometer, trip meter or any stored ECU memory while the device is active. Read our full guide here.
Are mileage blockers legal in the USA?
Mileage blockers are legal to buy and own in the USA. They are designed for legitimate use including dyno testing, track days, vehicle transport and off-road driving on private land. They must not be used to misrepresent a vehicle’s mileage when selling. Read more about legality here.
Can a mileage blocker be detected by diagnostics?
A quality vehicle-specific mileage blocker cannot be detected by standard OBD diagnostic scanners. Our devices intercept the speed signal across ALL vehicle modules simultaneously — no data mismatches, no fault codes, no warning lights. Full explanation here.
Will a mileage blocker damage my car?
No. Our devices are plug-and-play — no wires are cut, no circuits modified. Unplug it and your car returns to 100% factory condition instantly. Read the full answer here.
Is a mileage blocker the same as odometer correction?
No — they are completely different. A mileage blocker temporarily pauses mileage recording in real time. Odometer correction permanently changes historical mileage data — this is illegal in all 50 US states. See the full comparison.
How do I install a mileage blocker?
All our mileage blockers are fully plug-and-play. No cutting wires, no soldering, no specialist tools. Most installations take under 30 minutes. Full step-by-step installation guide here.

We supply vehicle-specific mileage blockers for over 40 car brands including BMW, Mercedes, Audi, Porsche, Ford, Chevrolet, Toyota, Lexus, Lamborghini, Ferrari, Rolls Royce, Tesla and many more. Browse all compatible vehicles here.
How long does shipping take to the USA?
All orders ship free via FedEx and arrive in 1-3 business days anywhere in the USA — all 50 states including Hawaii and Alaska.
Do you offer a warranty?
Yes — every device includes a full 12-month warranty covering all manufacturing defects. If your device develops a fault within 12 months we replace it free of charge, no questions asked.
Can I use a mileage blocker on a track day?
Yes — track day use is one of the most common legitimate uses. Running your car on circuit adds high-stress miles that don’t reflect real-world road use. A mileage blocker keeps those track miles off your odometer history.
Does a mileage blocker work on electric vehicles?
Yes. We supply EV-specific mileage blockers for Tesla, Audi E-Tron, BMW i-Series, Mercedes EQC/EQS, Porsche Taycan and more — each engineered for the vehicle’s specific EV CAN-Bus architecture.
What is a CAN-Bus filter?
A CAN-Bus (Controller Area Network Bus) filter intercepts signals on your vehicle’s internal communication network. A CAN-Bus mileage blocker specifically intercepts the speed signal that would normally increment your odometer — preventing mileage from being recorded across all modules simultaneously.
Can I remove the mileage blocker after use?
Yes — simply unplug it and your vehicle returns to factory state instantly. No traces, no codes, no reset required.
How long does a mileage blocker last?
Our automotive-grade devices are built to last many years under normal use. Every device comes with a 12-month warranty. Full durability guide here.
