According to data from the International Lubricant Standardization and Approval Committee (ILSAC), using the recommended engine oil can improve fuel efficiency by up to 3–5% and extend engine life by several years. With hundreds of oil types, grades, and formulations available on the market, understanding how to select the correct engine oil is crucial for maintaining your car’s performance.

Understanding Oil Viscosity

One of the most important factors in choosing engine oil is viscosity, which refers to how thick or thin the oil is. Viscosity is indicated by numbers like 5W-30, 10W-40, or 0W-20.

• The first number (e.g., 5W) indicates the oil’s flow at low temperatures, ensuring your engine is protected during cold starts.
• The second number (e.g., 30) represents the oil’s thickness at operating temperature, providing adequate lubrication under heat and pressure.

For most modern vehicles, multi-grade oils like 5W-30 or 0W-20 are recommended, offering protection across a wide range of temperatures. Always refer to your vehicle’s owner manual to identify the correct viscosity rating. Using oil with incorrect viscosity can increase engine wear or reduce fuel efficiency.

Synthetic vs. Conventional Oil

Engine oils are generally divided into conventional, synthetic, and semi-synthetic types.

• Conventional oil is suitable for older vehicles with standard engines and provides basic lubrication at a lower cost.
• Synthetic oil offers superior performance in extreme temperatures, better oxidation resistance, and enhanced engine cleanliness. It is recommended for modern vehicles, high-performance cars, and long oil change intervals.
• Semi-synthetic oil combines the benefits of both, offering improved protection over conventional oil while being more affordable than full synthetic.

In 2024, synthetic oils accounted for more than 60% of passenger vehicle oil sales worldwide, reflecting their increasing importance for modern engines.

Considering Engine Type and Mileage

The type of engine and the car’s mileage also influence the oil choice.

• Gasoline engines typically require lighter oils like 0W-20 or 5W-30.
• Diesel engines often need heavier oils or oils specifically formulated to handle soot and high compression.
• For high-mileage vehicles, oils with additives that reduce leaks and oil consumption can prolong engine life.

Using the correct formulation ensures optimal lubrication, prevents sludge buildup, and maintains engine efficiency.

Additives and Special Formulations

Modern engine oils include various additives that improve performance:

• Detergents keep engine parts clean by preventing deposits.
• Anti-wear agents reduce friction on moving components.
• Viscosity index improvers ensure consistent performance across temperature ranges.
• Corrosion inhibitors protect metal surfaces from rust.

Some oils are specifically designed for turbocharged engines, high-performance vehicles, or hybrid systems. Always check the API (American Petroleum Institute) and ACEA (Association des Constructeurs Européens d’Automobiles) ratings to ensure compatibility with your engine.

Changing Oil Regularly: Key to Longevity

Even the best oil loses effectiveness over time. Most manufacturers recommend oil changes every 5,000–10,000 miles for synthetic oils and every 3,000–5,000 miles for conventional oils, depending on driving conditions. Severe driving situations—like frequent stop-and-go traffic, towing, or extreme temperatures—may require more frequent changes.

Regular oil changes prevent sludge accumulation, maintain fuel efficiency, and protect engine components, ensuring long-term reliability. Skipping oil changes is one of the most common causes of premature engine failure.

Check the Oil Level with the Dipstick

Most cars have a dipstick that allows you to measure the oil level and condition. To use the dipstick, follow these steps: Warm up your engine: Drive your car for a few minutes to warm up the engine, as this will help the oil flow more easily and provide a more accurate reading. Turn off the engine: Allow your engine to cool down for a minute before opening the hood. Locate the dipstick: Find the dipstick, which is usually marked with a bright handle, often yellow or orange.

This video can explain it more:

Remove the dipstick and wipe it clean: Pull it out and wipe off any oil on it with a clean cloth or paper towel. Reinsert the dipstick: Put it back into the tube and push it all the way down. Check the oil level: Remove the dipstick again and examine the oil level. There should be markers on the dipstick indicating the minimum and maximum levels. If the oil level is below the minimum mark, your car may need more oil, and it’s a good sign that it’s time for an oil change.

Inspect the Oil’s Condition

The color and texture of your oil can also help you determine if it’s time for an oil change. Color: Fresh oil is typically amber or light brown. If the oil looks dark brown or black, it’s a sign that it’s become dirty and may need to be changed. Consistency: Rub the oil between your fingers to check its texture. If it feels gritty or has small particles in it, it’s likely time for a change. Clean oil should feel smooth and slightly oily without any noticeable debris.

Look for the Oil Change Light

Many modern cars are equipped with an oil change light on the dashboard. If this light turns on, it’s a signal from the vehicle’s computer that it’s time to change the oil. Keep in mind that this light may also be triggered by factors like time or mileage, so be sure to follow the manufacturer’s recommended schedule.

If you drive your car frequently, the alternator will keep the battery charged. But if you don’t drive often, the battery may lose its charge. If your car sits for long periods, it’s a good idea to start it up every few days to keep the battery active. Alternatively, consider using a battery maintainer or trickle charger, which is a device that helps maintain the charge without overcharging the battery.

Limit Short Trips and Keep the Battery Clean and Secure

Dirt and grime can build up on the battery, which may cause it to discharge faster. Clean the battery case regularly with a damp cloth to remove dirt, and ensure that the battery is secured in its holder. A loose battery can cause vibrations that may damage the internal components of the battery.

Dirt and grime can build up on the battery, which may cause it to discharge faster. Clean the battery case regularly with a damp cloth to remove dirt, and ensure that the battery is secured in its holder. A loose battery can cause vibrations that may damage the internal components of the battery.

Frequent short trips where the engine doesn’t run long enough to fully recharge the battery can wear down the battery over time. If possible, try to combine errands or take longer drives. This allows the alternator to recharge the battery fully, which helps preserve its life.

Keep the Battery in a Cool, Dry Place

Extreme temperatures can shorten the life of a car battery. In hot weather, the heat can cause the battery fluid to evaporate, and in cold weather, the battery can freeze, especially if it’s already weak. If you live in an area with extreme weather, consider getting a battery with higher cold-cranking amps or installing an insulated battery blanket to protect it.

By following these simple steps, you can extend the life of your car battery, ensuring that your vehicle continues to start smoothly and reliably, even with frequent use. Regular maintenance and paying attention to your car’s battery will save you money and hassle in the long run.

Changing your engine oil is necessary for a number of reasons: Oil lubricates engine parts to prevent metallic friction, oil ensures perfect engine compression, oil evacuates impurities and deposits them in the oil filter and oil cools the engine

When should I change my oil?

You should change your car’s oil when the “oil pressure” light on your dashboard comes on. The frequency of oil changes depends on a number of factors: The year your vehicle was put on the road, the number of kilometers driven, engine type gasoline or diesel and type of driving.

How often should I change my oil? As a general rule, a gasoline car needs its oil changed every 10 to 15,000 km. Our advice for diesel cars is to change the oil every 7,000 km. Generally speaking, the older your car, the more frequent the service. The oil filter should be changed at every oil change and every 30,000 km at the latest.

For peace of mind, we recommend that you change your car’s oil at least once a year. It’s a good thing that oil changes are often included in your car’s manufacturer’s service, so make the most of it!

How do I change my oil?

Before starting the oil change, make sure the car is parked on a level surface to facilitate the draining of used oil and the subsequent filling of the tank. Here are the main steps in the oil change process: Let the used oil drain into the oil pan; Replace the drain plug gasket with a new one, if necessary; Remove the oil filter and replace it with a new one; Replace the drain plug when draining is complete;

Fill the tank with new oil using the funnel, taking care not to exceed the maximum volume indicated on the dipstick or in the vehicle service booklet.

Why change your oil?

It’s important to change the oil in your vehicle for a number of reasons: Keeping engine parts running smoothly. As a general rule, the engine converts the reciprocating motion of the pistons into a circular movement, thus enabling the thermal energy generated to be used to propel the vehicle. To achieve this conversion, the engine is equipped with several small moving parts which rub against each other at very high temperatures. So, without the right engine oil for trucks and heavy-duty vehicles, or a quality engine oil for light-duty vehicles, the friction between these parts could create scratches or abrasions, eventually preventing the engine from running smoothly.

Extending engine life: As you use your vehicle, dust particles and other residues accumulate in the oil filter as the oil evacuates them. So, when you change your oil and filter, your engine is free of all the dirt that can shorten its life. Reduce corrosion: Over time, the consistency of the oil in your vehicle changes, becoming more liquid and less viscous. This reduces its effectiveness against humidity, opening the door to rust. Changing your oil helps reduce the risk of engine corrosion.

When should I have my oil changed?

 The frequency of oil changes can vary from one vehicle to another. Ideally, you should follow the manufacturer’s recommendations and those of your authorized service center. With the development of increasingly high-tech cars, the frequency of oil changes has become extremely variable. For some cars, it may be 5,000 kilometers, for others 50,000 kilometers. That’s why some groups are equipping their vehicles with a system capable of assessing oil quality and indicating when a check-up is required. Examples include Renault, BMW and Mercedes. However, there are a number of criteria that influence the frequency of oil changes. One of these is the fuel used. As a general rule, we recommend that you change the oil in a diesel engine every 5,000 to 7,000 kilometers. In the case of gasoline engines, this operation is generally carried out every 10,000 to 15,000 kilometers. To find out how many kilometers you need to change your oil, you also need to take into account how your car is used. A vehicle that is mainly driven in the city will need an oil change more regularly than one that is driven on the freeway.

This video can explain it more:

Should I have my oil changed every year?

 Whether or not you should have your oil changed every year depends on a number of factors. As a general rule, if your car doesn’t cover a large number of kilometers each year, an annual oil change is recommended. This ensures that the engine remains in good working order, even if the mileage recommended by the manufacturer is not reached.

However, for newer cars or vehicles that are driven a lot, the frequency of oil changes may be dictated by the vehicle’s service book or dashboard, which indicates when an oil change is required. In these cases, the interval can vary between 10,000 and 30,000 km. It should also be noted that the type of fuel used influences the frequency of oil changes. Diesel engines may require oil changes more frequently than gasoline engines. In short, each vehicle has its own specificities, and it is always advisable to refer to the manufacturer’s recommendations to determine the right interval for an oil change.

Before immobilization

Do not leave your car outside: the first question to ask is: where will you park your car during this period? It is highly recommended to leave your vehicle indoors, away from dust and, in winter, snow, rain and cold. Preferably, park your car in a heated garage and not too wet. If you do not have a garage at your disposal, cover your car with a cover. In summer, this will protect your car from the sun, which tends to damage joints and tarnish colors. Throughout the year, it will prevent corrosion caused by moisture and air pollution.

This video can explain it more:

 Clean your car: Car Cleaning Once you have found the place where you will park your car, you will first have to clean it. It is very important to start by washing and drying the body, especially in case you plan to cover your car with a protective cover. Indeed, if the body of your vehicle is covered with dust and other dirt, the installation of a cover could scratch the paint. Also remember to clean your rims. If possible, apply an anti-rust product on your rims as well as on other parts not covered with paint.

Fill the fuel tank and check your brake and cooling fluids

If you leave the fuel tank empty for the duration of the immobilization, dust and other particles will settle to the bottom and may form a mud-like layer inside the tank. When you want to restart your vehicle, the engine will draw from this layer of mud and will be quickly damaged. However, it is not useful to fill your gas tank to the maximum, on the contrary. Gasoline loses in quality over time, so it’s better to fill your tank half when your vehicle is not driving, and then top it up before you hit the road. This will allow the «recent» gasoline to mix with the one that was already present in the tank, thus enhancing the qualities of the latter. It should also be noted that condensation may appear on the walls of the tank that are not in contact with gasoline. To avoid this phenomenon, we strongly recommend that you fill your tank half full with premium fuel.

Brake liquidity is recommended to replace your brake and cooling fluids with new liquid. Provide coolant four seasons, which is resistant to both frost and corrosion. Conversely, the antifreeze present in the coolant for the winter causes corrosion risks.

Tips for consuming less with an automatic gearbox

Whether for yourself or for the fleet of vehicles belonging to your company, association or local authority, there are a number of easy-to-apply techniques for reducing fuel consumption when driving an automatic car.

Accelerate gradually: On manual cars, it may be advisable to accelerate quickly in order to stabilize your speed quickly and waste less fuel. With automatic gearboxes, the opposite is true. You don’t need to rev up to reach cruising speed. As the gears change automatically, you should accelerate gradually. What’s more, even if you push the accelerator pedal to the limit, your vehicle won’t accelerate, and your fuel consumption will increase drastically.

Choose the latest automatic transmission models

There was a time when automatic gearboxes were known to consume much more fuel than manual gearboxes. This is less and less true. The latest automatic gearboxes are much more fuel-efficient than their predecessors.

This video can explain it more:

If you decide to buy a car, it’s better to invest a little more and get a recent model. In addition to adopting eco-driving habits, your investment will pay for itself over time. Remember: when the time comes to buy a car, look at the vehicle’s year on the market. Over the years, manufacturers have had to adapt to more and more ecological standards, making car boxes more economical.

Choose the automatic D or Drive program

The auto gearbox system is not the same as that of manual gearboxes. If you want to learn how to consume less with an automatic gearbox, we strongly recommend using program D. D or Drive mode is the forward driving position. This is where the gears are shifted.

Some cars have a sport mode. Logically, if you’re looking to reduce fuel consumption, this is not the program to choose. Likewise, shifting into neutral is not recommended when driving. It tends to interfere with engine braking as the engine revs down. Remember: to reduce fuel consumption with an automatic gearbox, choose mode D and not mode S or N when the vehicle is in motion.
