Malang, en.SERU.co.id – Heading home for Eid (mudik Lebaran) can be much more fuel-efficient—and kinder to your wallet and the environment—by adopting eco-driving habits. This approach significantly lowers fuel consumption and vehicle emissions. Experts emphasize that the key lies in driving style and smart vehicle management during long journeys.
Fauzan Ammar Putra, a lecturer in Mechanical Engineering at Universitas Muhammadiyah Malang (UMM), explains that fuel efficiency heavily depends on how drivers operate their vehicles. Keeping the engine performing optimally is crucial for long-distance travel like mudik.
“Eco-driving essentially means maintaining stable engine operation, especially at ideal RPM ranges, for more efficient combustion and reduced fuel use,” said Fauzan on Friday, March 20, 2026.
He stresses the importance of constant speed. Sudden acceleration and drastic speed changes are major culprits in wasting fuel. Proper gear usage is also vital—holding low gears too long forces the engine to work harder and burn more energy.
“Regulating RPM is equally critical. Engines have an ideal RPM range for efficient performance. Too high increases fuel consumption; too low strains the engine,” he added.
An often-overlooked habit is driving with windows open. Aerodynamically, this increases drag, requiring more power. Fauzan recommends using air conditioning wisely, preferably in recirculation mode, for better efficiency.
Meanwhile, ITB automotive expert Yannes Martinus Pasaribu highlights three main factors for energy efficiency during mudik: driving style, vehicle condition, and load management. Aggressive driving can reduce fuel efficiency by 15–30% on highways and 10–40% in heavy traffic.
“Sudden acceleration, high speeds, and abrupt braking are primary causes of fuel waste. Stop-and-go traffic without anticipation further spikes consumption,” he explained.
Technically, Yannes stresses pre-trip vehicle maintenance: regular servicing, timely oil changes, and clean air filters keep the engine optimal.
“Tire pressure is essential too. Properly inflated tires reduce rolling resistance—the force from tire deformation on the road,” he noted.
Drivers should also manage vehicle load wisely. Excess weight increases fuel use and risks engine overheating. Even an empty roof rack adds wind resistance and should be avoided.
“Vehicles with cruise control should use it to maintain steady speeds on toll roads,” he concluded. (aan/rhd)
