Reasons for oil leakage of an oil filter:

Improper installation of the oil filter: Improper tightening of the oil filter during installation can result in oil leakage.

Aging or damage of the oil filter sealing ring: Aging or damage of the sealing ring can impede full sealing effect of the oil filter, resulting in oil leakage.

Damage to the oil filter: A damaged or cracked filter can lead to oil leakage.

Over-tightening of the oil filter: Overtightening the oil filter can damage its sealing performance and cause oil leakage.

Installation of the oil filter without replacing the O-ring: If the O-ring is not replaced during oil filter installation, or if the O-ring has aged or damaged, oil leakage may occur.

Make sure the oil filter is installed correctly with an intact sealing ring, and check if the filter is damaged. Also make ensure that replacing the O-ring together with the oil filter can help solve oil leakage problem.

Comparison of oil filters:

The vika oil filter uses a 0.5MM high-strength shell with excellent tension strength and leakage prevention performance. Its filter paper is made of composite fiber material that is highly resistant to high temperature and carbonization. Thanks to high-quality material and advanced process, the filter paper is neat in appearance and provides better filtration of impurities.

Products of other brands: They use a shell made of scrap steel plates or an ultra-thin stamped shell. Non-curing starch filter paper is adopted, which is prone to softening and failure. The uneven filter paper leads to higher filtration resistance and poor filtration effect.
