Range Rover bad gas mileage – causes of bad MPG

Several factors can cause a Range Rover to have poor gas mileage, including its weight, engine size, driving habits, maintenance issues, tire condition, and aerodynamics.

Range Rovers are renowned for their luxurious features and powerful engines, but sometimes they don’t deliver the fuel efficiency we expect.

In this article, we will explore the various causes of bad gas mileage in Range Rovers, offering insights and solutions to help you improve your vehicle’s fuel economy.

What models are affected?

Common causes of bad gas mileage

There are several factors that can contribute to poor gas mileage in Range Rovers.

Understanding these causes can help you diagnose and address the issue effectively.

1. Engine problems

A poorly functioning engine can significantly impact fuel efficiency.

Issues such as worn piston rings, faulty spark plugs, or malfunctioning ignition coils can lead to decreased gas mileage.

It’s crucial to address these engine problems promptly to restore optimal performance and fuel economy.

2. Fuel system issues

Problems within the fuel system can also contribute to bad gas mileage.

Clogged fuel injectors, a dirty air filter, or a malfunctioning oxygen sensor can disrupt the air-fuel mixture, resulting in decreased fuel efficiency.

Regular maintenance of the fuel system components will help prevent these issues.

3. Tire maintenance

Believe it or not, the condition of your tires can affect your Range Rover’s gas mileage.

Underinflated tires create more rolling resistance, causing the engine to work harder and consume more fuel.

Proper tire inflation and regular tire rotations can help optimize fuel economy.

4. Driving habits

Your driving habits play a significant role in determining your Range Rover’s gas mileage.

Aggressive driving, excessive idling, and rapid acceleration can all negatively impact fuel efficiency.

By adopting more fuel-efficient driving techniques, such as maintaining a steady speed and avoiding abrupt changes, you can improve your Range Rover’s gas mileage.

5. Weight and cargo

Carrying unnecessary weight in your Range Rover can increase fuel consumption.

Extra cargo stored in the vehicle adds unnecessary burden and reduces fuel efficiency.

Periodically decluttering your vehicle and removing any excess weight can help enhance your gas mileage.

6. Fuel quality and octane rating

Using lower-quality fuel or a lower octane rating than recommended by the manufacturer can lead to decreased fuel efficiency.

Range Rovers are designed to perform optimally with specific fuel requirements, and deviating from these recommendations can have adverse effects on gas mileage.

7. Maintenance neglect

Regular maintenance is crucial to maintain your Range Rover’s fuel efficiency.

Neglecting routine maintenance tasks such as oil changes, air filter replacements, and spark plug inspections can result in decreased gas mileage.

Following Land Rover’s recommended maintenance schedule ensures your vehicle’s longevity and optimal performance.


Can a dirty air filter cause bad gas mileage?

Yes, a dirty air filter can restrict airflow to the engine, disrupting the air-fuel mixture. As a result, the engine may need to work harder, leading to decreased fuel efficiency.

How often should I change my Range Rover’s spark plugs?

The frequency of spark plug replacement depends on various factors such as the make and model of your Range Rover, driving conditions, and the type of spark plugs used.

Does bad fuel quality affect gas mileage?

Yes, using low-quality fuel or fuel with a lower octane rating than recommended can negatively impact your Range Rover’s fuel efficiency. It is advisable to use fuel that meets or exceeds the manufacturer’s recommendations for optimal performance and gas mileage.

Is it true that aggressive driving reduces fuel efficiency?

Yes, aggressive driving behaviors such as rapid acceleration, frequent braking, and speeding can all lead to decreased fuel efficiency. Maintaining a steady speed, avoiding sudden acceleration or braking, and following speed limits can help improve gas mileage.

How often should I rotate my Range Rover’s tires?

Tire rotation is typically recommended every 5,000 to 7,500 miles or as specified by your vehicle’s manufacturer. Regular tire rotation helps promote even tread wear, which can contribute to better fuel efficiency.


When it comes to bad gas mileage in Range Rovers, several factors can be at play.

It’s essential to diagnose the underlying causes accurately and address them promptly.

By keeping up with regular maintenance, adopting fuel-efficient driving practices, and addressing any engine or fuel system issues, you can improve your Range Rover’s gas mileage and enjoy a more efficient and cost-effective driving experience.
