Oil change

Regular oil changes are worthwhile: they prevent wear and tear and clean the engine so that you can enjoy your vehicle for a long time to come.

The engine is the heart of your vehicle. And engine oil is its blood. It fulfills a variety of tasks and nowadays must be able to do far more than just lubricate and cool: It has to function at high temperatures and pressures, clean the engine of combustion residues, abrasion, acids, water and fuel particles, protect it from corrosion and ensure it is leak-proof.

Why regular oil changes are so important

Engine oil is permanently exposed to extreme thermal and mechanical stress, causing it to consume and contaminate itself over time. For example, through combustion in the engine, dilution with fuel or condensation water, natural oil ageing and mechanical abrasion. Among other things, this encourages the formation of deposits due to combustion residues and can lead to serious consequences in the long term:

loss of compression and performance
poor exhaust emission values and risk of failing the emissions test
increased fuel and oil consumption
deteriorated lubricity
lubricant no longer reaches the individual lubrication points in the engine
increased engine wear up to the breaking of the timing chain and engine damage

To ensure optimum lubricity and protect the engine from damage, it is therefore unfortunately not enough to simply top up with fresh oil. Only a regular oil change, i.e. replacing the old, used oil with new oil, guarantees safe engine function and increases the service life of the engine.

How often should the oil be changed?

You can find out when it is time for the next oil change in your vehicle's service booklet. You can also take a look at the owner's manual. It will tell you how often you should change the oil. Many manufacturers specify fixed intervals: For cars, it is about once/twice a year or every 15,000/30,000 kilometers.

However, this cannot be generalized! When you should change the oil depends on your driving style. For example, how often you bring your vehicle up to operating temperature: If you mainly drive in the city, the oil ages more quickly.

The right motor oil for the oil change

Not all oils are the same: every engine is different and has specific oil requirements.

Modern engine oils are products specially developed for specific vehicle models - tailor-made spare parts, so to speak. Using inferior or even the wrong oil can have costly consequences:

loss of warranty
increased fuel consumption
increased risk of breakdown
reduced service life of the engine
estruction of the particulate filter and catalytic converter
major engine damage
