How do I split gas money fairly with passengers?

Divide the total trip fuel cost by the total number of travelers (including the driver). Our calculator automatically shows the cost per passenger and the total amount saved.

How does driving speed affect fuel consumption?

Highway driving at 120 km/h consumes up to 20% to 25% more fuel than driving at 80–100 km/h due to aerodynamic drag. Maintaining smooth acceleration and proper tire pressures significantly cuts fuel expenses.
