Possible reasons for leakage of an oil filter:

Improper installation: If the oil filter is not tightened properly during replacement or not installed according to the manufacturer's specifications, oil leakage may occur.

Aging or damage of sealing ring: The oil filter is typically provided with sealing rings, which may age, harden, or wear over time, and consequently lead to oil leakage.

Low filter quality: A low quality filter may experience oil leakage during use. It is therefore very important to use a high-quality filter.

Excessive or improper use of oil: If the oil level exceeds the normal range, it may cause excessive pressure and result in oil leakage of the filter.

Engine vibration: The vibration generated during engine operation may reduce the sealing effect of the filter, especially in the case of unstable installation or aged filter.

Corrosion or damage: If the filter shell is physically damaged or corroded, oil leakage may occur.

If oil filter leakage is found, the filter should be checked and replaced soon as possible to avoid oil loss and engine damage.

Oil filter comparison:

The vika oil filters adopt a 0.5MM high-strength shell with high tensile strength and leakage resistance. The filter paper is made of composite fiber, which is very resistant to high temperature and carbonization. The High-quality filter paper material features neat craftsmanship and provides better impurity filtering effect.

Other brand products use shells made of scrap steel plates or ultra-thin stamped shells. They adopt non-solidified starch filter paper that is prone to softening and failure. Their uneven filter paper results in increased filtration resistance and poor filtration effect.
