Vehicle Service and Preventive Maintenance Tracker

This system provides a centralized repository for tracking automotive service history, upcoming maintenance intervals, and total cost of ownership. It is designed to be updated immediately following any service event or repair. By maintaining this log, you ensure warranty compliance, improve resale value, and track part longevity.

Field Definitions

• Date: [YYYY-MM-DD] Format. Use a Date-formatted cell.
• Service Description: Brief summary of work performed (e.g., Oil Change, Battery, Tires).
• Mileage: Numerical value representing the odometer reading at the time of service.
• Cost: Currency format. Total amount paid including taxes and labor.
• Service Provider: Name of the mechanic, dealership, or "Self" if performed by the owner.
• Status: Dropdown selection: [Completed], [Pending], [Scheduled].

Essential Formulas

Calculate Total Maintenance Expenditure:

=SUM(D2:D100)

Calculate Average Mileage Between Services:

=(MAX(C2:C100)-MIN(C2:C100))/COUNT(C2:C100)

Highlight Pending Items: Use a Conditional Formatting rule on the "Status" column where the cell text contains "Pending" to fill with [Yellow] background.

Data Validation and Formatting Rules

1. Status Dropdown: Select the "Status" column, go to Data Validation, and set criteria to "List of items": Completed, Pending, Scheduled.
2. Date Validation: Set the "Date" column to "Date" format to ensure consistent sorting and filtering by calendar year.
3. Cost Formatting: Apply "Accounting" or "Currency" number format to the "Cost" column to ensure all entries align by decimal point for readability.
