Your mechanic asks "When was the last oil change?" and you can't answer. Maintenance records are scattered across paper receipts, spreadsheets, and driver memories. Without systematic tracking, you can't prove compliance or plan preventive maintenance. A proper maintenance logbook captures every service, repair, and inspection in one place.

What To Track In Your Maintenance Logbook
Track #1
Preventive Maintenance Services
Oil changes, filter replacements, fluid checks, tire rotations. Log date, mileage/hours, parts used, labor cost, next service due. Creates predictable maintenance schedule and prevents missed services.
Frequency:
Based on hours/miles or manufacturer schedule
Track #2
Repairs & Breakdowns
Unplanned repairs, component failures, emergency fixes. Document issue, root cause, parts replaced, downtime hours, total cost. Identifies recurring problems and high-cost vehicles requiring replacement.
Key Info:
What failed, why failed, cost to fix
Track #3
Safety Inspections
Pre-trip DVIRs, annual inspections, DOT compliance checks. Record inspection date, inspector name, defects found, repairs completed, sign-off. Proves compliance during audits and protects against liability.

Frequently Asked Questions
Q
What information must be in a maintenance logbook?
At minimum: vehicle identification, service date, mileage/hours, service description, parts used, labor performed, vendor/technician name, and cost. For DOT compliance, include inspection records with dates and findings. More detail is better—you can't over-document maintenance.
Q
How long should I keep maintenance records?
DOT requires 1 year minimum for inspection records. Best practice: keep entire vehicle lifetime plus 3 years after disposal. Needed for warranty claims, resale value proof, liability defense, and historical cost analysis. Digital records make permanent storage easy.
Q
Can I use a simple Excel spreadsheet as my logbook?
Yes for small fleets (1-10 vehicles). Excel works if you're disciplined about updating it after every service. Limitations: no automatic reminders, manual calculations, no photo attachments, risk of file corruption or loss. For 10+ vehicles, digital platforms save significant time.
Q
What's the difference between digital and paper logbooks?
Paper/Excel: Free, manual entry, no alerts, can be lost. Digital: Automated data entry from service invoices, instant PM reminders, cloud backup, photo attachments, integration with telematics and fuel cards. Small fleets can use paper; medium-large fleets need digital for efficiency and compliance.
