Seamless fuel transaction data flow from Comdata cards to maintenance tracking
Connect to Comdata's data export system to automatically import every fuel purchase daily. Each transaction includes date, time, station location, vehicle number, driver ID, gallons, price per gallon, total cost, and odometer reading. Transactions link automatically to vehicles by card assignment or unit number. Historical data from the past 12 months imports during setup for complete fuel history visibility.
Automatically calculate MPG by comparing Comdata purchases to GPS odometer data or manual entries. Cost per mile metrics combine fuel expenses with mileage for true operating costs. Fleet dashboards display average MPG, total spend, and efficiency comparisons. Anomaly detection flags unusual consumption patterns—sudden MPG drops indicate maintenance needs like dirty filters, tire issues, or engine problems.
Link Comdata data to maintenance activities to identify cost patterns. Track fuel costs before and after repairs to validate effectiveness. Fraud detection compares purchase locations to GPS positions—alerts trigger when purchases occur far from vehicle locations. Monitor for suspicious activity like multiple fill-ups in short periods or after-hours transactions. Driver-specific cards provide accountability and identify training needs.

Stop collecting handwritten receipts and typing data into spreadsheets. Comdata integration automatically imports every purchase with complete details. Save 8-12 hours weekly on manual entry. Eliminate data entry errors from illegible receipts or lost paperwork. Daily import keeps fuel data current without administrative delay.
Declining fuel efficiency signals maintenance problems before breakdowns occur. MPG drops of 10-15% indicate dirty air filters, low tire pressure, failing oxygen sensors, or engine issues. Catch problems early through automated monitoring and proactive alerts. Correlate fuel consumption with maintenance history to validate repair effectiveness. Use fuel data to optimize preventive maintenance intervals.
Cross-reference Comdata purchase locations with GPS vehicle positions to detect fraud instantly. Alerts trigger when purchases occur 50+ miles from vehicle location. Identify unauthorized after-hours purchases or weekend fill-ups. Monitor for excessive fill-up frequency indicating theft or siphoning. Driver-specific cards provide accountability. Spending controls and merchant restrictions prevent unauthorized purchases.

Oxmaint imports Comdata transaction data through automated file exports. Transaction data includes date, time, location, driver, vehicle, gallons, price, cost, and odometer reading. Transactions match to fleet vehicles automatically. Historical data from the past 12 months imports during setup. Integration takes 3-5 business days with Comdata account credentials and file export configuration.
MPG calculation compares fuel purchases to vehicle mileage. With GPS integration, Oxmaint uses GPS odometer readings for automatic calculation. Without GPS, drivers enter odometer at pump or manually. System calculates: (Current Odometer - Previous Odometer) ÷ Gallons. Historical trending tracks 30-day, 90-day, and 12-month averages. Anomaly alerts trigger when MPG drops 10-15% below normal.
Declining fuel efficiency indicates maintenance problems. Sudden MPG drops of 10-15% signal dirty air filters, low tire pressure, failing oxygen sensors, clogged fuel injectors, or transmission issues. Oxmaint correlates MPG trends with maintenance history—if MPG doesn't improve after service, additional problems exist. Proactive monitoring catches issues before breakdowns, reducing emergency repairs.
Yes. With GPS integration, Oxmaint cross-references purchase locations with vehicle positions. Fraud alerts trigger when purchases occur 50+ miles from vehicle location. Additional detection includes: excessive fill-up frequency, unusually large purchases, after-hours transactions, and suspicious patterns. Driver-specific cards show who made each purchase. Comdata's spending controls and merchant restrictions prevent unauthorized purchases.
Reports include: Fuel Expense Summary (total spend, gallons, price trends), MPG Analysis (efficiency by vehicle/driver), Cost Per Mile Analysis, Driver Fuel Efficiency Reports, Exception Reports (anomalies and unauthorized purchases), Budget Variance Reports, and Transaction Detail Exports. All reports export to Excel, PDF, or CSV.
Comdata offers nationwide acceptance at 14,000+ locations, competitive fuel discounts, enhanced fraud protection with driver ID verification, Level 3 transaction detail, and robust reporting.
