Frequently Asked Questions

What is MPG and how does it relate to l/100km?

MPG (miles per gallon) is the US/UK fuel efficiency measure. To convert: l/100km = 235.215 / MPG. A car with 30 MPG uses about 7.8 l/100km.

How much can I save with a more fuel-efficient car?

Upgrading from 10 l/100km to 6 l/100km saves 40% on fuel. At €1.50/liter and 15,000 km/year, that's €900/year savings.

Does driving style affect fuel consumption?

Yes, aggressive driving (rapid acceleration, speeding) can increase fuel consumption by 15-30%. Steady speeds and anticipating traffic save fuel.

Is diesel more economical than gasoline?

Diesel engines are typically 15-20% more fuel-efficient, but diesel fuel may cost more. Calculate total cost based on local prices and your driving distance.
