For businesses utilizing mileage for services like pay-per-mile insurance or vehicle maintenance tracking, accurate mileage verification is crucial. OBD-II (On-Board Diagnostics II) ports are often mentioned in this context, leading to a common question: Can You Get Mileage From Obd2? While OBD-II ports offer a wealth of vehicle data, understanding their capabilities and limitations regarding mileage is essential. This article delves into whether OBD-II can accurately provide mileage data and explores superior alternatives for reliable mileage verification.
Decoding OBD-II and Mileage Data Access
The OBD-II system is primarily designed for vehicle diagnostics and monitoring emissions. It collects data from various sensors throughout the car, providing insights into engine performance, emissions control systems, and more. While the OBD-II system does track data related to vehicle operation, it’s important to understand how it handles mileage.
Contrary to common assumptions, OBD-II ports do not directly provide the odometer reading as displayed on your car’s dashboard. Instead, OBD-II devices, such as dongles, typically estimate mileage based on trip data and GPS location. These devices infer the distance traveled by tracking the start and end points of journeys and using location data to calculate the approximate miles driven.

This indirect method of mileage calculation introduces several limitations when relying solely on OBD-II for accurate mileage verification.
The Shortcomings of OBD-II for Reliable Mileage Tracking
While OBD-II dongles offer some level of mileage estimation, they fall short when precise and dependable mileage verification is needed, particularly for applications like insurance and usage-based services. Here’s why:
Inaccuracy of Estimated Mileage Readings
As mentioned earlier, OBD-II mileage from dongles is not a direct odometer reading. It’s an approximation derived from location data and trip calculations. This estimation process is inherently prone to inaccuracies. Factors like GPS signal variations, urban canyons, and even the algorithms used by different dongles can lead to discrepancies. Furthermore, if a dongle incorrectly registers the beginning or end of a trip, even minor errors can compound into significant mileage miscalculations over time. For applications demanding precise mileage, these inaccuracies can be problematic.
Practical Issues and Potential for Failure
OBD-II dongles, being hardware devices, are susceptible to practical issues and failures that can disrupt mileage tracking. Installation can be cumbersome for some users, requiring them to physically plug the device into the OBD-II port. A loose connection can lead to intermittent data collection or complete device failure. Accidental dislodging of the dongle is also a common occurrence. Moreover, some OBD-II devices can draw excessive power from the car’s battery, especially when the vehicle is parked, potentially leading to battery drain and customer dissatisfaction. These reliability concerns make OBD-II dongles less than ideal for consistent and hassle-free mileage verification.
Vulnerability to Tampering and Mileage Fraud
A significant drawback of OBD-II dongles is their susceptibility to intentional tampering. Policyholders or individuals seeking to manipulate mileage data can easily unplug the dongle before long trips to avoid accurate tracking. While some systems might detect device disconnection, the delay in detection allows for mileage fraud to occur. By the time the dongle is reconnected, a considerable distance might have been driven without being recorded. This creates opportunities for premium leakage in insurance and undermines the integrity of mileage-based services.

Privacy Considerations and User Trust
In an era of increasing privacy awareness, OBD-II dongles raise privacy concerns among users. These devices often operate as “black boxes,” lacking transparency regarding the data they collect, how it’s transmitted, and how it’s utilized by insurance companies or service providers. This lack of transparency can breed skepticism and mistrust among policyholders who are wary of constant tracking and potential misuse of their data. Building customer trust is paramount, and the opaque nature of OBD-II dongles can hinder this process.
Cost and Logistical Expenses
Implementing OBD-II dongle solutions involves significant costs beyond just the device itself. Businesses must procure the dongles, manage inventory, handle shipping to customers, and deal with replacements for damaged or lost devices. If customers switch providers before the hardware costs are recouped, it leads to financial losses. These logistical and hardware-related expenses make OBD-II dongles a less cost-effective solution compared to software-based alternatives.
The Advantages of Car APIs for Superior Mileage Verification
Modern car APIs (Application Programming Interfaces) offer a compelling software-based alternative that overcomes the limitations of OBD-II dongles for mileage verification. By directly accessing vehicle data through the car manufacturer’s cloud, APIs provide a more accurate, reliable, and user-friendly solution.
Accurate and Direct Odometer Readings via APIs
Unlike OBD-II estimations, car APIs can retrieve the actual odometer reading directly from the vehicle’s computer system. This ensures highly accurate mileage data, eliminating the inaccuracies inherent in estimation methods. With precise odometer readings, businesses can offer fair and accurate pricing, and customers can be confident in the mileage data being used.
Streamlined User Experience and Enhanced Reliability
Car APIs offer a frictionless and reliable user experience. The onboarding process is entirely software-based and can be completed within a few clicks through a mobile or web application. Users simply connect their car account and grant permission for data access. There’s no need for hardware installation, shipping delays, or concerns about device failures. This ease of use significantly improves customer satisfaction and reduces drop-off rates during onboarding.
Tamper-Proof and Secure Mileage Data
Car APIs provide tamper-resistant mileage verification. The system can regularly and automatically retrieve odometer readings directly from the vehicle. This eliminates the possibility of users manipulating or hiding mileage data, ensuring data integrity and preventing mileage fraud. Businesses can rely on API-driven mileage verification for accurate and trustworthy data.
Privacy-Focused and Transparent Data Access
Car APIs prioritize user privacy and transparency. Reputable API platforms employ granular permission systems, allowing users to see exactly what data is being requested (e.g., odometer, location, fuel level). Users have full control over granting or denying access to specific data points. This transparency builds trust and addresses privacy concerns associated with hardware-based solutions.
Cost-Effective and Scalable Solution
Car APIs offer a cost-effective and scalable pricing model, typically based on SaaS (Software as a Service). Businesses avoid the upfront and ongoing costs associated with hardware, shipping, and replacements. API solutions scale easily with business needs, providing a more efficient and economical approach to mileage verification.
Conclusion: Embracing Modern Solutions for Mileage Verification
While OBD-II ports and dongles might seem like a viable option for mileage verification at first glance, their limitations in accuracy, reliability, security, and user experience become apparent upon closer examination. For businesses requiring precise and dependable mileage data, car APIs emerge as the superior solution. They offer accurate odometer readings, enhanced user experience, robust security, and cost-effectiveness. As the automotive industry becomes increasingly connected, embracing software-driven solutions like car APIs is the future of reliable and efficient mileage verification.
For businesses seeking to leverage the power of car APIs for mileage verification and other vehicle data needs, exploring platforms like Smartcar can be a valuable step. These platforms offer comprehensive API solutions to access vehicle data with user consent, enabling innovative and efficient services.
