Free Printable Fuel Economy Tracking Sheet (PDF)

This is a free, one-page printable fuel log in PDF format. Each row is one fill-up: date, odometer reading, gallons (or liters), price per unit, total cost, and MPG for the tank. When MPG starts drifting down for no obvious reason — tire pressure, air filter, dragging brake — a written log catches it before your dashboard would.

How to use this sheet

  1. Print the PDF and keep it in the glove box with a pen.
  2. At every fill-up, log date, odometer, gallons, and price — takes ten seconds at the pump.
  3. Subtract the previous odometer to get miles this tank; divide by gallons for MPG.
  4. After a few tanks, you'll have a baseline. Watch for drift downward — that's usually the earliest sign something needs attention.
  5. Keep the sheet for tax records if the vehicle is used for business or self-employed work.

Questions

Is this log really free?

Yes. The PDF is free to download and print — no sign-up, no email.

Do I need to fill up to full every time?

For MPG accuracy, yes — 'full-to-full' fill-ups give the cleanest numbers. Partial fills muddy the miles-per-gallon math, though total cost tracking still works.

Why track MPG when the car shows it on the dash?

Dashboard MPG readouts are computed and can drift or reset. A written log is your own baseline — if the car says 30 MPG but your log says 26, the log is usually right.

Is there an app version?

Yes — MotorLog for iPhone logs fill-ups with automatic MPG, service records, and repairs, and exports a clean history PDF. Core is free, no account needed, data stays on your device.

Want the log to analyze itself?

MotorLog for iPhone tracks the same things in seconds and shows you the patterns — free core, no account, and everything stays on your device.
