Standard consumer credit cards capture (only the merchant name and total dollar amount). Commercial fleet cards capture Level III data , which tracks the exact product purchased down to the line item. This includes the number of gallons, the cost per gallon, and the National Association of Convenience Stores ( NACS ) product code.
At its core, is a safety and functional classification. It breaks down into two distinct parts:
For each fuel entry include:
Many large truck stops and fleet fueling networks run proprietary software logic (such as WEX Cross Roads or EFS SecureFuel ). These closed-loop systems often reserve specific data fields for internal tracking or regional discount programs. If an off-network or third-party card tries to read or execute a transaction using these reserved pathways, the gateway returns a exception. 3. Overly Restrictive Fleet Spending Controls
. It serves as a placeholder or "reserved" data field within a standardized communication protocol (such as those used by Gilbarco Veeder-Root undefined fuel-reserved for proprietary
By restricting fuel specs to "proprietary," manufacturers ensure that only they (or authorized partners) can service the machinery and sell the necessary fuel, maintaining a controlled service ecosystem. 3. What to Do When You See This Alert
However, the practice of reserving fuel for proprietary use also raises concerns regarding market competition, equity, and environmental sustainability. When a significant portion of the fuel supply is reserved for exclusive use, it can limit access to energy resources for other stakeholders, potentially stifling competition and hindering economic growth. Moreover, the prioritization of proprietary fuel reserves over public or external access can exacerbate existing energy inequalities, particularly in regions where energy access is already limited. Standard consumer credit cards capture (only the merchant
Often, this state is normal during specifically scheduled operations. If it appears unexpectedly, it could indicate a malfunction in the sensor system or a failure in the dual-fuel management system.
If this occurred on a private fleet site, confirm if the "Proprietary" code is intended for specific internal tracking that requires special authorization on the user's fleet card profile. FLEET CARDS – REPORTING OF ALTERNATIVE FUELS At its core, is a safety and functional classification
Unlike standard OBD-II codes (such as P0171 or P0420), this message indicates that data from the fuel telemetry system is encrypted, locked, or unrecognized by third-party diagnostic tools. Understanding the Error Breakdown
