Driving Habits to Maximize Fuel Efficiency

Driving style is one of the most significant factors affecting fuel consumption. Small changes in how you operate your 2021 Acura ILX can lead to substantial improvements in fuel economy.

1. Accelerate Smoothly and Gradually

Aggressive acceleration wastes fuel by demanding more power from the engine than necessary. Instead, apply the accelerator smoothly and gradually, allowing the engine to operate efficiently within its optimal RPM range. This approach reduces fuel consumption and wear on engine components.

2. Maintain Steady Speeds

Driving at a steady speed, especially on highways, improves fuel efficiency. Use cruise control when possible to maintain consistent speeds, reducing unnecessary acceleration and deceleration. Avoid rapid speed changes that require extra fuel.

3. Anticipate Traffic Flow

Look ahead to anticipate stops and slowdowns. Gradually easing off the accelerator instead of braking abruptly conserves momentum and fuel. This technique also reduces wear on your brakes and tires.

4. Limit Idling Time

Idling consumes fuel without moving the vehicle. Turn off the engine during long stops, such as waiting in a drive-thru or at a railroad crossing. Modern engines like the ILX’s restart smoothly and quickly, minimizing inconvenience.

5. Use Air Conditioning Wisely

Air conditioning increases engine load and fuel consumption. Use it sparingly, especially at lower speeds. At highway speeds, open windows can cause aerodynamic drag, so balancing AC use and window position is key for optimal efficiency.

Vehicle Maintenance Tips for Fuel Economy

Proper maintenance ensures your Acura ILX operates at peak efficiency. Neglected maintenance can lead to reduced fuel economy, higher emissions, and costly repairs.

1. Regular Oil Changes

Engine oil lubricates moving parts, reducing friction and wear. Dirty or degraded oil increases engine resistance, reducing fuel efficiency. Follow Acura’s recommended oil change intervals using the specified synthetic oil grade to maintain optimal engine performance.

2. Keep Tires Properly Inflated

Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check tire pressures monthly and inflate them to the manufacturer’s recommended levels, found on the driver’s door jamb or owner’s manual.

3. Use the Correct Grade of Motor Oil

Using the recommended oil viscosity and grade ensures the engine runs smoothly. Higher viscosity oils can increase internal friction, negatively affecting fuel economy.

4. Replace Air Filters Regularly

A clean air filter ensures proper airflow to the engine, improving combustion efficiency. A clogged air filter restricts airflow, causing the engine to consume more fuel. Inspect and replace the air filter at scheduled intervals or more frequently in dusty environments.

5. Maintain the Fuel System

Fuel injectors and the fuel system should be kept clean to ensure efficient fuel delivery. Use quality fuel and consider fuel system cleaners periodically to prevent buildup that can impair performance.

6. Check and Replace Spark Plugs

Worn or fouled spark plugs can cause misfires and incomplete combustion, reducing fuel efficiency. Replace spark plugs according to the maintenance schedule to maintain optimal engine performance.

Optimizing Aerodynamics and Reducing Weight

Reducing aerodynamic drag and vehicle weight can significantly impact fuel consumption, especially at higher speeds.

1. Remove Excess Cargo and Roof Racks

Extra weight requires more energy to move, increasing fuel consumption. Remove unnecessary items from your trunk and backseat to lighten the vehicle. Also, remove roof racks or carriers when not in use to reduce wind resistance.

2. Close Windows at High Speeds

Open windows increase aerodynamic drag, forcing the engine to work harder. At highway speeds, keeping windows closed and using the climate control system is more efficient than driving with open windows.

3. Use Aerodynamic Accessories

If you use accessories like mud flaps or spoilers, ensure they are designed to minimize drag. Consult with your Acura dealer for approved aerodynamic enhancements that do not compromise fuel economy.
