How To Get More Mileage With Regular Servicing

In today’s world of rising fuel prices and growing environmental concerns, fuel efficiency is no longer just a bonus—it’s a necessity. Every car owner seeks ways to get more mileage from every litre of fuel, and while there are many strategies to improve fuel economy, regular car servicing remains one of the most effective and often overlooked solutions.

This article explores how regular vehicle maintenance can lead to better fuel efficiency, prolong vehicle life, and save money in the long run. Whether you drive a hatchback, a luxury SUV, or a commercial vehicle, the principles of regular servicing apply to all.

The Link Between Regular Servicing and Fuel Efficiency

Vehicles are machines made of complex, interdependent systems. Over time, wear and tear, friction, and lack of proper care can reduce a vehicle's performance. When a vehicle is not serviced regularly, it has to work harder to perform the same functions, which often translates to higher fuel consumption.

Routine servicing ensures all major components are functioning efficiently. This includes:

• Engine performance checks
• Oil and filter changes
• Tyre inspection and alignment
• Air and fuel system cleaning
• Spark plug replacements

When these systems work at optimal levels, the engine doesn’t overwork, which means it burns fuel more efficiently, giving you better mileage per litre.

Engine Health and Its Impact on Mileage

Oil Change and Lubrication

One of the most fundamental aspects of a car service is engine oil replacement. Engine oil lubricates the engine’s internal parts, reducing friction and wear. Over time, oil becomes thick, dirty, and less effective, leading the engine to work harder than necessary.

Using the recommended grade of engine oil and changing it at regular intervals helps maintain smooth engine operation, reduces internal resistance, and improves fuel economy.

Air Filter Maintenance

The air filter plays a crucial role in maintaining the right air-fuel mixture in the combustion chamber. A dirty or clogged air filter restricts airflow, causing the engine to burn more fuel to generate power.

During servicing, technicians inspect and replace air filters as required, which helps maintain ideal combustion conditions and thus improves fuel efficiency.

Spark Plug Efficiency

Worn-out or faulty spark plugs can lead to incomplete combustion, resulting in poor engine performance and fuel wastage. Regular inspection and timely replacement of spark plugs during service intervals ensure consistent and complete combustion, which translates into better mileage.

Tyres: The Unsung Hero of Fuel Efficiency

Tyre Pressure and Alignment

Under-inflated tyres are a major culprit in poor mileage. When tyre pressure is low, rolling resistance increases, meaning the engine needs more power—and more fuel—to move the car.

During regular servicing, tyre pressure is checked and corrected. Wheel alignment is also examined, as misaligned wheels create unnecessary drag and reduce fuel efficiency.

Tyre Rotation and Tread Wear

Regular tyre rotation ensures even wear, which helps maintain consistent handling and optimal road grip. Proper grip reduces slippage and enhances the vehicle’s ability to move efficiently, minimizing fuel wastage.

Fuel System Maintenance

The fuel injectors, fuel pump, and fuel lines play a direct role in how your vehicle consumes petrol or diesel. Over time, fuel systems may develop deposits that block injectors and reduce pressure, leading to inefficient fuel delivery.

Fuel Injector Cleaning

Professional servicing often includes fuel injector cleaning, which removes carbon and dirt build-up. Clean injectors ensure precise fuel delivery and optimal spray patterns, improving combustion efficiency and reducing fuel consumption.

Replacing Fuel Filters

Fuel filters trap impurities and contaminants. If not replaced regularly, they can restrict fuel flow to the engine. Regular servicing includes checking and replacing fuel filters, which helps maintain a clean and steady fuel supply to the combustion chamber.

The Role of the Exhaust System in Mileage

Your vehicle’s exhaust system, including the catalytic converter and oxygen sensors, influences mileage more than most people realize.

A malfunctioning exhaust system can lead to incorrect air-fuel ratios and cause the engine to burn more fuel. During servicing, these components are checked for blockages or leaks that might hinder performance. A clean, properly functioning exhaust system ensures optimal emissions and supports better fuel efficiency.

Importance of Regular Software Updates

Modern vehicles use engine control units (ECUs) and onboard computers to manage fuel injection, ignition timing, and throttle response. Manufacturers regularly release software updates to improve fuel efficiency and performance.

During servicing, technicians check for and apply the latest ECU updates, ensuring your car runs on the most fuel-efficient parameters available.

Battery Condition and Mileage

While the battery doesn’t directly influence fuel consumption, a weak or failing battery puts more load on the alternator. This increased resistance means the engine must work harder to power electrical systems, consuming more fuel in the process.

Regular servicing includes a battery health check, ensuring that your vehicle’s electrical system is operating efficiently and without unnecessary strain on the engine.

Transmission and Lubricants

Whether manual or automatic, the transmission system must operate smoothly for optimal performance. Transmission fluid reduces friction and allows for seamless gear shifts.

If the fluid is old, burnt, or low, the transmission may slip or delay gear shifts, making the engine work harder. Servicing involves checking and changing transmission fluid when required, which contributes to better mileage and driving comfort.

Maintaining the Cooling System

An overheating engine runs inefficiently and can consume more fuel. The cooling system, including the radiator, coolant, and thermostat, keeps the engine at the ideal operating temperature.

During servicing, technicians inspect coolant levels and flush the system if necessary. A well-maintained cooling system ensures the engine runs efficiently, helping reduce fuel consumption.

Avoiding Short-Term Fixes and DIY Risks

Many drivers try to improve mileage by using aftermarket fuel additives or DIY hacks without understanding the vehicle's mechanics. While some additives can be helpful, they should never be used as substitutes for professional servicing.

Unqualified maintenance can lead to long-term damage and decreased mileage. Professional service centres have the tools, experience, and knowledge to diagnose issues accurately and apply proven maintenance practices.

Economic and Environmental Benefits

Cost Savings Over Time

Regular servicing may seem like an expense, but it results in substantial cost savings over time. Improved mileage means fewer fuel stops and less strain on the engine, leading to fewer breakdowns and costly repairs.

Lower Carbon Footprint

An efficiently serviced vehicle produces fewer emissions. By getting more mileage from the same amount of fuel, you are reducing your carbon footprint and contributing to a greener environment.

Choosing the Right Service Centre

Selecting a reputable and well-equipped service centre is key to ensuring quality work. Certified service stations follow manufacturer guidelines, use genuine parts, and keep a detailed history of your vehicle’s maintenance. This not only improves mileage but also maintains your car’s resale value.

Look for service centres that offer:

• Transparent pricing
• Digital service records
• Skilled technicians
• Warranty on services
• Customer support

Conclusion

Getting more mileage from your vehicle is not about using shortcuts—it’s about consistent care and timely attention. Regular servicing plays a crucial role in maintaining all the systems that influence fuel consumption, from the engine to the tyres and beyond.

While many drivers focus on fuel brands or driving styles to improve mileage, neglecting routine maintenance is a major mistake. Make vehicle servicing a priority, not just a formality, and your car will reward you with better fuel economy, smoother performance, and a longer lifespan.
