Motorists can reduce petrol and diesel fuel use by 25% by removing one item

Drivers could cut petrol and diesel fuel consumption by as much as 25% by getting rid of one item, according to leading experts. Analysis from motor insurance specialists GoSkippy stressed that removing a car roof rack may make a massive difference. Roof racks can be important accessories for cyclists heading on long trips or holidays as the weather gets warmer.

However, many individuals will leave their roof racks installed on their vehicles long after a holiday having a major impact on fuel use. Experts encouraged individuals to not use their car as a “dumping ground” with weight playing a major impact on how much petrol or diesel is burned.

GoSkippy explained: “The heavier your car is, the more fuel is consuming. A lot of us might use our car as a bit of a dumping ground for things we don’t need immediately.

“By having a clear out, you can reduce the overall weight your car needs to propel up the road.

“This could be small things like rubbish and clothes or larger things like removing a roof rack when it’s not being used.

“Speaking of roof racks, one study found having a roof rack on your car may be costing you as much as 25% more in fuel! So, it’s worth thinking if it’s something you really need on your journey.”

The actual benefit enjoyed by motorists once they remove a roof rack is likely to vary from vehicle to vehicle.

According to Motorway, roof racks can affect fuel consumption by anywhere from 5% to 15%.

The motoring specialists explained that the tool will tend to increase the surface area on top of a vehicle.

This can significantly increase aerodynamic drag which will lead to more air resistance around the vehicle.

To counter this, car engines have to work harder to maintain the same speed which burns more fuel.

Motorway added: “Increased aerodynamic drag forces the engine to use more fuel to maintain speed, particularly at motorway speeds.

"Even when empty, a roof rack can reduce efficiency due to its effect on airflow and increased resistance. With this in mind, it’s worth removing the rack when you don’t need to use it.”
