What the site covers
The guides cover the parts of fuel economy that owners can understand and influence: what affects mileage, driving habits, tire pressure, maintenance, weather and seasons and tracking your own numbers. There is also a page of common myths and a general guide to electric range.
Who it's for
Everyday drivers who want to spend less on fuel, understand why their mileage moves around, or get a feel for how electric cars use energy. No mechanical knowledge is assumed. Where a job needs tools or training, we say so.
How we handle facts
We use figures that official sources such as the US Department of Energy and the EPA publish, and we round them. When results vary with the vehicle or conditions, we say "about" and give a range rather than a single number. The example fill-up log on the home and tracking pages uses made-up numbers to show the arithmetic. It doesn't describe a real car.
Rules and ratings change. Fuel blends, testing methods and tax mileage rates are all updated from time to time, so we explain how things work and point you to the source that keeps the current figure.
What we don't do
- We don't sell anything, run ads or use partner links.
- We don't list fuel or electricity prices, which change constantly and differ by place.
- We don't rate vehicles or recommend brands, products or shops.
- We don't give tax, legal or financial advice. For mileage records used for taxes, check the IRS or a tax professional.
Where to check details
- Your owner's manual for tire pressure, oil grade, fuel grade, charging advice and the service schedule.
- The door-jamb placard for tire pressures.
- fueleconomy.gov, run by the US Department of Energy and the EPA, for official vehicle ratings and fuel-saving guidance.
- A qualified mechanic for warning lights, brakes, steering and anything that affects safety.
A note on safety
No fuel saving is worth a safety risk. We never suggest drafting behind trucks, coasting in neutral, switching off the engine while moving or overinflating tires. Drive at speeds that suit the road and conditions.
