What are the signs that indicate the end of the oil filter life?

There are some signs that can indicate the end of the oil filter's life and the need to replace it, including:

1. Increased engine temperature: A clogged or old oil filter can cause the engine temperature to rise due to weak or no oil flow at all.
2. Increased fuel consumption: If the oil filter is old or clogged, it may cause an increase in fuel consumption due to insufficient lubrication of moving parts inside the engine.
3. Deterioration of oil quality: An old or clogged oil filter may cause deterioration of oil quality and contamination with impurities and deposits, which can lead to engine damage.
4. Increased noise: If the oil filter is old or clogged, it may cause an increase in engine noise due to insufficient lubrication of moving parts.
5. Warning sign: Some vehicles have a warning sign on the dashboard indicating the need to replace the oil filter when it reaches the end of its life.

Usually, it is recommended to replace the oil filter every 5,000-7,500 kilometers or every 6 months, and the owner's manual for the vehicle should be checked to determine the recommended period for replacing the oil filter.
