Factors Responsible for Poor Fuel Economy in a Car

A lot of factors affect the fuel economy of a car.

However, a sudden drop in fuel economy clearly indicates that the car has some mechanical malfunctions which need immediate attention.

So, everyone should be aware of the reasons behind the poor fuel economy in a car.

DEGRADED MOTOR OIL

Motor oil lubricates and minimizes friction among different components of the engine.

Properly lubricated engine works more efficiently and consumes less fuel.

However, motor oil degrades over time due to the extreme temperature and contamination.

Degraded oil should be replaced after a certain time interval.

Skipping an oil change not only affects the performance of the engine but also increases fuel consumption.

TIRE PRESSURE AND TREAD DEPTH

Underinflated or overinflated tires with an inadequate amount of tread depth adversely affects the fuel economy of a car.

So, tires should be properly inflated and should have an optimum amount of tread depth to run smoothly without consuming more fuel.

FAULTY FUEL INJECTION SYSTEM

Clogged or defective fuel injection system does affect the fuel economy of a car.

Besides, errors in the engine control unit or ECU also negatively affects the fuel economy of a car.

AGGRESSIVE DRIVING

Driving habit of a person does affect the fuel economy of a car.

So, it is highly recommended to avoid aggressive driving habits to get proper fuel economy as well as to avoid fatal collisions.

CLOGGED FILTERS

Air and motor oil filter used in the engine protects it from different types of contaminants.

However, accumulation of foreign bodies and contaminants in such kinds of filters not only affects the fuel economy but also affects the performance of the engine.

IRREGULAR MAINTENANCE

Maintenance is the key to keep a car in working order.

However, irregularities in the maintenance of a car not only triggers major mechanical failure but also affects the fuel economy of a car.

There are several other factors which affect the rate of fuel consumption in a car.

Poor gas mileage indicates that the engine or other components associated with it have some deformities which need immediate attention.
