Experts reveal the secret fuel thief that is costing motorists hundreds a year Irish drivers are losing hundreds of euros annually to a hidden drain on their fuel economy, according to motoring experts. The culprit isn’t just aggressive driving or idling—it’s a combination of overlooked habits that silently erode mileage and inflate costs at the pump. Simple driving habits are costing Irish motorists up to €300 a year in fuel, RSVP Live reports. These include carrying unnecessary weight in the boot, driving with underinflated tyres, and using roof racks or bike carriers when not in use. Each of these factors increases aerodynamic drag or rolling resistance, forcing the engine to perform harder and burn more fuel. Experts from the Irish Mirror highlight that removing roof racks when not needed can save up to 10% on fuel consumption, as they significantly disrupt airflow over the vehicle. Similarly, keeping tyres inflated to the manufacturer’s recommended pressure improves fuel efficiency by reducing resistance—underinflated tyres can increase fuel use by as much as 3%. Carrying extra weight, such as golf clubs, tools, or luggage left in the car permanently, also has a measurable impact. For every 50kg of unnecessary weight, fuel consumption can rise by approximately 2%. Over a year, this adds up to significant avoidable expense, particularly for drivers who frequently build short trips where engines operate less efficiently. Motoring specialists from The Journal advise that combining several slight inefficiencies—like driving with a roof box, underinflated tyres, and excess weight—can compound losses, pushing annual fuel waste beyond €300 for the average Irish motorist. Addressing these issues requires no mechanical expertise; simple checks before each journey can yield noticeable savings. The solution lies in routine vehicle maintenance and mindful loading. Experts recommend checking tyre pressure monthly, removing external accessories when not in use, and regularly clearing out the boot of non-essential items. These small adjustments, when practiced consistently, can restore lost efficiency and keep more money in drivers’ pockets. As fuel prices remain volatile, eliminating these avoidable drains offers a practical way for Irish motorists to reduce costs without changing their vehicles or driving routines. The savings are real, immediate, and within reach—starting with a glance at the tyre gauge and a quick clear-out of the car.
