Engine oil is one of the key elements that determine how long and in what condition our engine will operate. It’s more than just a lubricant. It acts as a protective shield, guarding the engine parts against wear and overheating, dissipating heat, helping to remove contaminants, and supporting the functioning of seals. Over time, however, the oil loses its properties, which is why regular oil changes are so important.
How Often Should Engine Oil Be Changed?
There is no definitive answer to the question of how often oil should be changed. It depends on the type of vehicle, driving style, and whether we are driving in challenging conditions. For passenger cars, oil changes are usually required every 10,000 to 20,000 kilometers, but it’s worth noting that for delivery vehicles, which are used in more demanding conditions (e.g., in the city or carrying heavy loads), oil changes may be necessary every 7,000 to 10,000 kilometers.
Real-life Example:
One day, a customer came to me with a delivery vehicle that regularly made short trips around the city. It works hard, transporting various goods. The customer noticed that the engine was getting louder, and the car was becoming less dynamic. After checking the oil, it turned out that it hadn’t been changed in over 15,000 kilometers, which is really too long in such a case. After the oil change, the engine came back to life, and the customer didn’t experience any issues for the following month. Such cases are a regular occurrence in the workshop.
What Affects the Frequency of Oil Changes?
Several factors influence how quickly oil loses its properties and requires replacement. It’s not just the mileage that matters, but also how the vehicle is used. From driving style to weather conditions, and engine type, each of these factors can make oil changes necessary more often than one might expect.
Driving Style Matters
From my experience, aggressive driving, frequent acceleration, and driving at high engine revs lead to much faster oil degradation. The engine heats up intensely, and the oil loses its properties more quickly. Of course, there’s nothing wrong with dynamic driving, but one should know that it results in the need for more frequent oil changes. Frequent acceleration “on red” or driving at high revs does not contribute positively to the engine’s longevity.
Operating Conditions
In harsh conditions – such as driving in traffic jams, in very low temperatures, or off-road – oil wears out faster. Frequent starts, short trips, or constant stopping in city traffic prevent the engine from properly warming up, meaning the oil cannot work effectively. These conditions can be considered “heavy” for the engine.
Real-life Example:
A customer who used his delivery vehicle in city traffic noticed that his car started to “smoke” under heavy loads. It turned out that he had old oil, which had lost its lubricating properties due to frequent stops in traffic jams. Changing to new oil and adjusting the oil change frequency solved the problem.
Engine Type Matters
Turbocharged engines, engines with a DPF filter, or those equipped with start-stop systems require more regular oil checks and changes. For turbocharged engines, the oil not only lubricates but also dissipates heat from the compressor. These units often face higher operating temperatures, which alters the oil properties more quickly than in standard engines.
Oil Type – Synthetic, Semi-synthetic, or Mineral?
Synthetic oil is more resistant to high temperatures and better protects the engine in demanding conditions. However, every type of oil has its intended purpose. Mineral and semi-synthetic oils may require more frequent changes, especially in vehicles that are heavily used. Synthetic oils, though more expensive, have a longer lifespan and are more efficient, but they also require regular monitoring.
Signs That Oil Should Be Changed
Sometimes, the car itself gives signs that something is wrong with the oil. The most common symptoms of worn-out oil are: increased fuel consumption, louder engine operation, starting problems, dark, almost black oil on the dipstick, unpleasant burnt smell under the hood, and the oil warning light on the dashboard.
Real-life Example:
One day, a driver came to me complaining of increased fuel consumption. I asked when the oil was last changed. It turned out it had been almost 15,000 kilometers, and the oil was already quite dark. After the oil change, the car returned to normal, and fuel consumption returned to the norm. This is a classic example of how oil can affect engine performance.
How to Properly Change Engine Oil?
Changing the oil is one of the simpler procedures, but it requires precision. Here are the steps to do it:
- Warm up the engine – not to boiling temperature, but to operating temperature. This allows the oil to become more fluid and easier to drain.
- Drain the old oil – unscrew the drain plug and allow the oil to flow freely into an appropriate container. Don’t forget to use protective gloves.
- Replace the oil filter – always replace the filter, as a worn filter may contaminate the fresh oil.
- Add new oil – according to the manufacturer’s recommendations, both in terms of quantity and specifications (viscosity, standards).
- Check the oil level – start the engine for a moment, and after a few minutes, check the oil level on the dipstick. If necessary, top it up.
Can Different Oils Be Mixed?
While technically you can add another oil of the same viscosity grade, it is not recommended. Each oil has its own unique blend of additives, and they don’t always mix well together. If you must add oil while on the road, try to choose one that is as close as possible to the oil currently used.
How to Care for Oil Quality on a Daily Basis?
In addition to regular oil changes, it’s also important to follow a few basic rules for maintaining oil quality daily. For example, avoid overloading the engine, especially right after starting it. The engine should have time to reach operating temperature, and the oil should be properly distributed across all parts of the engine. It’s also important to avoid overburdening the car, as this can cause the oil to wear out more quickly.
Investing in high-quality oils is also worth considering, especially if the car is used intensively. Oil is a crucial element in caring for the engine, so it’s not worth saving on its quality. When choosing the right oil, it’s best to follow the manufacturer’s recommendations. Oils that meet specific quality standards have longer durability and better lubrication efficiency, which impacts the engine’s longevity.
What Consequences Does Neglecting Oil Changes Lead To?
Neglecting regular oil changes can lead to serious consequences for the engine. Besides loss of engine efficiency, it can lead to the seizure of parts, faster wear of components, and even engine overheating. In extreme cases, when the oil becomes too old and stops performing its function, the engine may suffer a severe breakdown, leading to costly repairs. Prolonged driving on old oil can also lead to poorer fuel efficiency and the production of excessive emissions.
Summary
Changing the oil is one of the simplest yet most important procedures to ensure the longevity of the engine. Regular oil changes, adjusting the oil to the vehicle’s operating conditions, and choosing the right oil are investments that really pay off. By following these simple steps, we can avoid costly repairs and enjoy engine reliability for a long time.
Regular oil changes, choosing the right oil for the operating conditions, and maintaining oil quality on a daily basis are the key elements that ensure our engine runs smoothly and reliably. Let’s not forget these simple but important principles that will ensure our car’s long and trouble-free operation.
