Change the oil filters regularly according to the vehicle manufacturer's specifications.
Consequences of silted-up filter:
- Premature engine wear, even to the extent of engine damage
- Reduced engine power
- Increased oil consumption
- Escape of oil
Urban traffic means stress for the 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 that...
- ... 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
