Task of the oil filter

• To protect the engine against impurities in the oil

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
