When it comes to new cars, the process is simple – the car leaves the dealership, and with it, the owner receives a complete owner’s manual and a maintenance schedule for the coming years. Over time, however, the car changes ownership, and the documentation may be lost or no longer taken seriously.
This does not mean that caring for the engine becomes less important. On the contrary – an older engine requires more attention if we want to maintain its efficiency and longevity. As the engine ages, the components wear out, and the consumables no longer work as effectively as they once did. That’s why the key to keeping an older car in good condition is regular, thoughtful care. It doesn’t have to be expensive, but it should certainly be done systematically.
Regular oil changes and monitoring its condition
In new cars, the first oil change is often planned after 30,000 kilometers. For brand new engines, this practice is generally acceptable. However, as the engine ages, these intervals should be significantly shorter.
Oil has several important tasks: it reduces friction, cools the engine, and removes sludge and small impurities from the internal system. Over time, deposits increase, and worn-out parts require better lubrication. For older cars, it is recommended to change the oil every 8,000–10,000 kilometers, depending on driving style and operating conditions. Additionally, always choose oils from trusted brands and ensure they match the recommendations in the vehicle’s manual.
Equally important is regularly checking the oil level. In older engines, consumption of the lubricant is completely normal – seals, rings, and valve guides may have considerable mileage. The car may “consume” oil, even if there are no visible leaks. It is best to check the level every few hundred kilometers or before any long trips. This simple habit can save the engine from a serious breakdown.
Taking care of all the filters in the powertrain
Since we are talking about oil, it is impossible not to mention the oil filter. It is responsible for trapping impurities, metal shavings, and sludge that form during the engine’s operation. Changing the oil without replacing the filter makes little sense – it is an essential step with every oil change.
Similarly, it is worth taking care of the other filters: air and fuel. The former ensures an adequate amount of clean, dust- and particle-free air, which enters the cylinders and forms the air-fuel mixture. A clogged filter can lead to inefficient combustion, excessive carbon and sludge buildup, and, ultimately, poor engine performance. In older vehicles, where the engine already has significant mileage, the cleanliness of the intake air becomes especially important.
The fuel filter performs a similar function – it cleans gasoline or diesel fuel from impurities that could damage the injection system. Dirty fuel is particularly harmful to older fuel systems.
Always replace the oil filter with the oil change. The air and fuel filters can be replaced less frequently, typically every 2–3 years or according to the manufacturer’s recommendations. Regularly checking their condition, especially during seasonal service, is an investment that pays off quickly.
Systematic servicing and replacement of components
In older cars, not everything can be predicted, but regular servicing helps reduce the risk of serious failures. Importantly, it’s not just about changing oil or filters, but also about checking the condition of essential wear components. Timing belt, water pump, hoses, seals, or suspension parts – all of these parts wear out over time. Therefore, it is worth checking their condition regularly and not waiting for something to break. An older car requires more attention, but properly cared for, it will reward you with smooth driving for many more years.
