Does prolonged lack of maintenance increase fuel consumption in cars?

Prolonged lack of maintenance does not increase fuel consumption in cars. Below is detailed information about automotive maintenance: 1. Overview: Automotive maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain components of a vehicle, also known as vehicle upkeep. Currently, automotive maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, among others. 2. Purpose: The goal of automotive maintenance is to keep the vehicle clean and in normal technical condition, eliminate potential hazards, prevent malfunctions, slow down the deterioration process, and extend the service life.
As a veteran driver with over a decade of experience, I firmly believe that prolonged neglect of maintenance will inevitably increase fuel consumption. Last time when my car exceeded its service interval, the engine oil had severely degraded, causing increased engine friction. The car ran roughly as if gasping for air, and the fuel gauge dropped alarmingly fast—costing me an extra 200 yuan in fuel expenses over just one month. Upon inspection, the air filter was also clogged with dust, restricting airflow and leading to incomplete combustion. Additionally, the worn-out spark plugs caused misfires, making acceleration sluggish. After servicing—replacing the engine oil and filters—fuel efficiency improved by 15% immediately, and the car ran much smoother. Remember, underinflated tires also increase rolling resistance, further raising fuel consumption. Regular maintenance not only saves money but also extends your car’s lifespan and prevents roadside emergencies. I advise new drivers to develop the habit of timely maintenance—don’t wait until major issues arise to regret neglect. This small investment pays off in the long run: fuel savings and a healthier car.
