How to determine oil change intervals and why it is necessary to periodically add oil

It happens that the oil is subjected to premature aging. Typically, this happens to poor quality or counterfeit oils, but it may happen when using good oil, too. If the piston rings let in a lot of products of combustion from the cylinder to the interior chamber of the engine, the chemical components of the fuel can react with the oil. As a result, the oil can get oxidized and become too thick. It will no longer lubricate the engine the way it should.

If, after a start-up, the oil indicator on the dashboard does not go off for a long time, immediately check not only the oil level, but its condition as well: its colour and viscosity. If the oil has quickly become black and at the same time it flows down the dipstick very slowly, then it is an alarming sign. If the oil does not get dark at all in the course of the use of the vehicle, then the oil does not perform its function of cleaning, or it does not retain particles that are deposited on the inside surface of the engine.

However, oil should be checked regardless of what the oil control light shows. The fact remains that the vehicles equipped with engines with small volume of fill-in may signal an abnormal condition too late – you should agree that the loss of one liter of oil out of three is not the same as the loss of one liter out of five in engines with a large volume.

There is a special danger when drivers fill in oil at suspicious filling-in stations directly from the barrel. A large amount of sediment containing an over-proportional amount of the active substances may accumulate at the bottom of the barrel. And someone, according to the theory of probability, will get all this deposit. When that oil starts to work in the engine, you will need to overhaul the engine just after a few days.

If the premature deterioration of oil has not been caused by problems of oil itself, it means that wrong oil has been filled in.

The specified form no longer exists or is currently unpublished.

    Cabin Air Filters

    The cabin air filter is responsible for cleaning outside air entering the vehicle. Because up to 100,000 litres of air can be blown into the vehicle’s interior in less than an hour, it can easily become clogged with debris. Unfortunately, a blocked cabin filter will not be effective, resulting in a below-par heating and cooling system, and causing the air inside the vehicle to become more polluted than the air outside up to six times more. Similarly, bacteria and fungi can accumulate in the filter, leading to unpleasant smells in the cabin. Fitting a high-performance cabin filter, such as Delphi, is essential in eliminating these harmful pollutants and odours, safeguarding both you and the air conditioning (A/C) system.
