Fuel efficiency determines how often you must fill up your car and its environmental impact. If you notice a sudden drop in gas mileage, it’s essential to speak with an auto technician about possible causes. You don’t want to waste money on gas or increase your carbon footprint, so consider the following issues.

Why Your Car’s Mileage Is Dropping

1. Failing Fuel Injector

The fuel injector is responsible for driving gas into the engine, so when it fails or leaks, your car’s mileage will suffer. Faulty injectors are also accompanied by the inability to start your vehicle, poor idling conditions, and an overall decrease in performance. These indicators lead to severe problems, so it’s important to see an auto technician.

2. Using the Wrong Oil

The wrong or outdated motor oil won’t properly lubricate the engine’s parts, gradually decreasing fuel efficiency and mileage. Schedule an oil change every 7,500-10,000 miles, although some vehicles require one every 3,000 miles. Consult the vehicle’s manual for the recommended distance before an oil change and speak with an auto repair professional.

3. Bad Driving Habits

Sometimes, it’s the driver, not the car, causing the drop in fuel efficiency. Accelerating too quickly, revving your engine, and driving aggressively will waste fuel. Drive carefully and patiently to help increase your gas mileage.

4. Using the Wrong Tire Pressure

Tire pressure is precisely determined so that tires maximize energy use. When tires are under-inflated, they’ll require more fuel to function, wasting gas. Check your tire’s recommended pressure — located below the tread on the side— and inspect them once a month with a handheld gauge.

5. Bad Oxygen Sensors

Oxygen sensors regulate how much air is mixed in with the fuel. When levels are off, it drastically impacts fuel efficiency—sometimes by 20%. If there’s a drop in gas mileage, auto technicians will scan for any issues with the car’s connection to the sensors.
