The importance of REGULAR oil changes

Oil plays a significant role in ensuring a long engine service life: It undertakes a variety of tasks, all of which are crucial for the smooth running of each engine process – from lubrication and damping, to cleaning, cooling and sealing, right up to corrosion protection. Today, we’ll be taking a look at the importance of regular oil changes, and how this can save you money in the long run.


What you should remember as a car owner

In order for the oil to perform all of its tasks successfully, it must have a correspondingly high grade; regular oil and oil filter changes are therefore critical. What many people don’t know, is that the replacement intervals should be shortened when driving frequently in urban traffic and using bio fuels. Consequently, it is advisable to also always consider your personal driving style and change the oil more frequently if required.

Important for the oil change

As a rule, only oil of the correct grade and specification for the vehicle must be used. The oil filter should also always be replaced in the process, as only a clean filter has sufficient capacity to remove contaminants, such as dust, metal abrasion, and combustion residues from the oil.

An irregular oil change interval can be expensive

When the engine is running, resin spall from the oil can compoind wth road dust, loose combustion residues, and condesation water to cause the oil to sludge. Deposits on the oil filler cap are a clear indication of this.

Sludge and other deposits in the oil can in turn lead to failure of the oil pressure regulating valve in the oil pump, the effect of which varies depending on the valve position at the time of failure.

  • A large proportion of oil drawn in by the pump is being drained into the oil sump directly via the valve – the consequence: insufficient lubrication.
  • Unregulated oil pressure with high pressure peaks – identified by a bloated oil filter.

In the event of either of these happening, replacing the oil and the filter no longer rectifies the issue, because the deposits will have caused damage to the oil pressure regulating valve as described above. To prevent further issues including possible engine damage, it is essential to have the exact defects and their causes identified and rectified by a repair shop. A swollen oil filter may lead to fretting marks in the controller casing and on the controlled-expansion piston of the oil pressure regulating valve, which requires the replacement of the oil pump.

As you can see, delaying an oil change may save money in the short term. However, it also increases the risk of terminal engine damage associated with correspondingly high costs. Simply put, putting off oil changes can result in considerable damage to engine components, and it is these repair costs that make a simple oil and filter change pale in comparison!
