❓ FAQ
Why is my MPG lower than EPA rating?
EPA tests use controlled conditions. Real-world factors like cold starts, short trips, AC use, traffic, and driving style typically reduce MPG 10-20%.
How often should I track MPG?
Track every fill-up for accurate data. Sudden drops in MPG can indicate maintenance issues like low tire pressure or clogged filters.
