Optimise Your Fuel Efficiency: The Definitive Guide

Inflation has risen considerably year after year since the onset of the pandemic and due to the global political climate, resulting in a renewed focus on fuel efficiency. These cost increases, including car and oil prices, have particularly affected UK car owners. Furthermore, there is growing public awareness of the escalating challenges of global warming and how cars contribute to them.

Car utilisation is seeing a significant shift from fuel-hungry vehicles to the use of fuel-efficient vehicles in the UK. In this guide, learn the true meaning of what fuel efficiency means, how to increase fuel efficiency, and much more.

Defining Fuel Efficiency

Maximising a car’s mileage through smart maintenance and thoughtful usage is the fundamental concept of fuel efficiency. Each car manufacturer approaches vehicle economy differently to strike a balance. Some brands prioritise high power output, even at the expense of fuel efficiency, while others focus on affordability over performance.

A car owner’s responsibility is to make an effort to maximise their vehicle’s fuel efficiency to its fullest potential. Now, let’s explore some of the ways to optimise your cars.

Maintain Your Vehicle

Every car requires a consistent maintenance schedule that an owner must follow diligently to ensure fuel efficiency does not decline. Here are some engine checkpoints that directly affect your vehicle’s mileage:

• Fuel-Air Mixture: Check the fuel injectors, air filters, and sensors to ensure the combustion cycle occurs correctly. If not, ask for an engine repair from Acton Service Center to enhance your car’s fuel efficiency.
• Lubrication: Properly lubricating critical components ensures the engine does not suffer from issues like knocking. Inefficient engine operation, including valve misfires and degraded spark plugs, can result from improper lubrication.
• Cooling Issues: Overheating, caused by a lack of coolant or a worn-out radiator, can lead to the car automatically reducing power output to manage overheating, which can be detrimental to the vehicle.
• Fuel Leakage: Any leaks or clogs in the fuel or exhaust system lead to fuel wastage and significantly decrease your car’s fuel efficiency.

A proper car diagnosis and regular servicing scheduling can identify all engine issues. Get comprehensive full car servicing at ASC for an affordable car ownership journey.

Drive Efficiently

While your engine might be performing smoothly, how you drive can be a critical reason behind the lagging fuel efficiency. Habits like speeding, sudden braking, and pushing the car to its limits can be personally fulfilling but lead to higher fuel consumption and wear. Try to drive more relaxed and avoid constant revving, high acceleration, and deceleration.

If you maintain a steady speed at all times, your car will reward you with long-term savings and less waiting time at the fuel pump.

Plan Your Trips

Every car manufacturer has a separate mileage rating for city and highway driving, with the differences being quite significant. Lower speeds, as well as frequent stop-and-go traffic on city roads, contribute to decreased fuel efficiency. In contrast, highways allow smoother rides, and higher speeds are more favourable for fuel economy.

Plan your journey according to real-time traffic updates and weather conditions, and avoid congested routes.

Reduce Weight and Drag

The UK is a hub for campers and off-roading enthusiasts who embark on trips to remote locations. Many owners install large steel racks on their cars and load them with unnecessary items. All the additions and added weight can start to affect the car’s performance and gas mileage over a period.

Start by identifying potential areas where the car can be lighter and more aerodynamic to reduce wind drag. When you’re not going on trips, remove the racks and ensure your vehicle carries only the necessary items.

Do Not Idle Your Car

When you’re at a stoplight or stuck in traffic, turn off the car whenever an opportunity arises. An idling car engine consistently consumes fuel and rapidly depletes the gas tank. If you are using the AC to cool the vehicle, consider alternately turning it off and on at 5-10 minute intervals.

It is considered one of the most common ways to increase car fuel efficiency.  

Proper Tire Pressure

Rolling resistance refers to the friction generated between the tires and the road. An average car tire is filled with air between 24 and 36 PSI (Pounds per Square Inch) to ensure it is adequately inflated and provides the lowest rolling resistance.

Every drop in tire pressure increases the resistance by at least 1.4%, directly proportional to an increase in fuel consumption. Consistently check your tire pressure to ensure it is optimally inflated within the recommended PSI range.

AC Functioning

The impact of air conditioning (AC) on your comfort within a car can be significant. The cabin can feel like an unbearable hotbox in the summer without a fully functioning cooling system. In the winter, the AC unit plays a vital role in moderating temperatures and preventing the cabin windows from fogging.

The downside of the AC unit is that it can directly increase fuel consumption by a substantial margin of 20 percent. Balancing the use of AC conditioning can be quite a challenge; therefore, here are some ways to optimise the cooling in your car’s interior:

• Ensure your vehicle is parked in shaded areas during the summer and open regions during the winter.
• Open all the windows and doors to allow trapped heat to escape from the car.
• Avoid opening windows too frequently when using the AC on long trips.
• Ensure that no debris or blockage stuck in the AC unit.
• Recirculate the cold air in the car to reduce strain on the air conditioning system.

Steady RPM

Ensure that the tires’ rolling resistance remains controlled by maintaining optimal tire pressure. Additionally, you can further reduce rolling resistance by keeping the RPM (Revolutions Per Minute) at proper levels at all times.

Ideally, your car must operate within the ideal range of 1500-3000 RPM to maintain a healthy balance between performance and fuel efficiency.

Conclusion

You have now learned about the various ways to increase fuel efficiency, and it will ensure fuel savings for the lifespan of a car.

Remember: Your driving style and the car’s state are interlinked as mechanical wear and tear progressively increase. Maintain a healthy balance between performance and conservative driving when navigating different road conditions.
