Fuel Tracking Guide
How to Keep Track of Fuel Expenses
Tracking fuel expenses helps you understand the true cost of running your vehicle. Most drivers underestimate their monthly fuel spend because they do not record every fill-up consistently.
The Right Way to Track Fuel Expenses
- Record your odometer reading at every fill-up — not just when the tank is full
- Log the exact fuel quantity in litres or gallons
- Enter the price you paid — not the pump price
- Note whether it was a full or partial fill-up
- Attach your receipt for accurate business or tax records
- Review your monthly totals at the end of each month
How to Calculate MPG (Miles Per Gallon)
MPG measures how many miles your vehicle travels on one gallon of fuel. A higher MPG means better fuel efficiency and lower running costs.
MPG Formula
MPG = Miles Driven ÷ Gallons Used
Example: If you drove 300 miles and used 10 gallons, your MPG is 30. FuelEx calculates this automatically after every fill-up — no manual maths needed.
Example calculation
Miles driven
300 miles
Gallons used
10 gallons
Your fuel economy
30 MPG
300 miles ÷ 10 gallons
How to Calculate Fuel Cost Per Mile
Fuel cost per mile tells you exactly how much your vehicle costs to drive each mile or kilometre — one of the most useful numbers for budgeting.
Fuel Cost Per Mile Formula
Cost Per Mile = Total Fuel Cost ÷ Miles Driven
Track your running costs
FuelEx calculates your fuel cost per mile and per kilometre automatically. You can view this for each fill-up and as a monthly average.
What is a Good MPG for a Car?
Most modern petrol cars average between 25–40 MPG. Diesel vehicles typically achieve 35–55 MPG. SUVs and trucks average 15–25 MPG. Hybrid vehicles can exceed 50 MPG.
Petrol cars
25–40 MPG
Diesel vehicles
35–55 MPG
SUVs and trucks
15–25 MPG
Hybrid vehicles
50+ MPG
A consistent drop in your MPG over time can signal tyre pressure issues, engine problems, or driving habit changes. FuelEx helps you spot this early.
