Frequently Asked Questions

How do I find my car's MPG?

Check your owner's manual, the sticker on the driver's door, or websites like fueleconomy.gov. Real-world MPG is often 10-15% lower than EPA estimates.

What affects fuel efficiency?

Speed, tire pressure, AC usage, cargo weight, driving style, and terrain all affect fuel efficiency. Highway driving is typically more efficient.
