Welcome back to our educational blog series, “Driving to Save Petrol.” In our previous post, we delved into fuel-saving driving techniques that can significantly reduce petrol consumption. However, adopting efficient driving habits is just one piece of the puzzle. Another equally critical aspect is vehicle maintenance. Proper care and regular maintenance can vastly improve your car’s fuel efficiency, saving you money and extending the life of your vehicle. Let’s explore how keeping your car in top shape can lead to better fuel economy.
1. Keep Your Tires Properly Inflated
Tire pressure plays a pivotal role in fuel efficiency. Under-inflated tires can increase rolling resistance, forcing your engine to work harder and, as a result, consume more fuel. According to studies, for every 1 PSI drop in the average pressure of your tires, your car’s gas mileage can decrease by 0.2%. Ensuring your tires are inflated to the manufacturer’s recommended levels can improve your vehicle’s fuel efficiency by up to 3%. Regular checks, ideally once a month, can keep your tires at their optimal pressure.
2. Regular Engine Checks and Oil Changes
The heart of your vehicle, the engine, requires regular check-ups to run efficiently. Worn spark plugs, sticky valve springs, or a clogged fuel injector can impair your car’s performance and fuel economy. Additionally, using the right type of oil can make a significant difference. Modern engines are designed to operate with specific oil viscosities. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1-2%. Regular oil changes, as recommended by your vehicle’s manufacturer, ensure that your engine runs smoothly, minimizing unnecessary fuel consumption.
3. Air Filter Replacement
A dirty air filter restricts the flow of air to the engine, which can harm performance and efficiency. Replacing a clogged air filter on older vehicles with carbureted engines can improve their fuel efficiency by as much as 14%. In modern fuel-injected cars, while the impact on fuel economy might be less, a clean air filter is crucial for optimal engine performance and longevity.
4. Minimize Vehicle Load and Drag
Extra weight demands extra energy to move. Every additional 100kg in your vehicle could reduce your KPL (kilometers per liter) by about 1%. It’s advisable to keep your trunk and rear seat clear of unnecessary items that add weight. Similarly, accessories like roof racks can create aerodynamic drag, which further reduces fuel efficiency. Removing these when not in use can improve your fuel economy, especially at highway speeds.
Implementing Maintenance for Fuel Efficiency
These maintenance tips are not just about saving fuel; they’re also about preventative care, which can save you from costly repairs down the line. By keeping your vehicle well-maintained, you ensure it runs as efficiently as possible, reducing your petrol costs and contributing to environmental conservation.
Join us for the next installment of our series, where we will dive into the intricacies of petrol grades and how choosing the right type can affect your car’s performance and fuel consumption. Remember, every step towards more efficient vehicle use not only helps your wallet but also the planet.
