The job of the oil filter is to protect the engine against impurities in the oil such as dust, metal particles, combustion residue or soot particles. With modern engines it is vital that replacement oil filters are made to the same high standards that the vehicle manufacturer specifies.
The consequences of a dirty filter:

Premature engine wear, which can even lead to engine damage

Reduced engine power

Increased oil consumption

Oil leaks

Urban traffic means stress for oil

On short-distance trips and in stop-and-go traffic, the oil and the oil filters should be changed more often than the replacement intervals specified by the vehicle manufacturer. Frequent cold starts lead to more condensation and a fuel surplus in the combustion mixture. This means:

Unburnt hydrocarbons and condensation enter the oil which leads to premature aging of the oil

At high engine temperatures, these components evaporate in the oil circuit, which further reduces the lubrication quality
