Tires with the correct air pressure: if the tire pressure is low, it will cost the vehicle’s engine to work harder; the engine will spend more fuel and the vehicle will require more energy to move. The manufacturer recommends the ideal air pressure in the vehicle’s manual.
Avoid unnecessary overload: If your car is carrying unnecessary weight, it will make your car move slower; therefore, it consumes more gasoline. For example: specialists point out that the use of carrier on the roof could increase by up to 35% normal fuel consumption of the vehicle.
Using the fuel recommended by the manufacturer of the vehicle: This will help to keep the car in good performance.
Avoid moving with little fuel: Avoid having less than half of the fuel tank. If there is little fuel, the vehicle is running less efficiently.

Use continuous and long routes: Choose routes that allow you to maintain a constant speed and avoid making speed changes or gears very frequently. The first gear is that puts the vehicle in motion, so it consumes more fuel.
