Frequently Asked Questions
Which is more accurate – miles or kilometers?
Both unit systems are equally accurate. The calculator uses precise conversion factors (1 mile = 1.60934 km, 1 gallon = 3.78541 liters) for all calculations.
Can I calculate fuel efficiency in liters per 100 km?
While we display km/l by default, you can convert to l/100km by dividing 100 by your km/l result. Example: 10 km/l = 10 l/100km.
How often should I check my vehicle’s mileage?
For most drivers, checking every 2-3 fill-ups provides meaningful data. Business users may want to track every trip for accurate records.
Why does my calculated mileage differ from the manufacturer’s claim?
Manufacturer tests use ideal conditions. Real-world factors like traffic, terrain, and driving habits affect actual mileage.
Fuel-Saving Tips
- Maintain proper tire pressure (can improve mileage by up to 3%)
- Remove excess weight (100 lbs reduces efficiency by about 1%)
- Use cruise control on highways
- Avoid aggressive acceleration and braking
- Follow recommended maintenance schedules
