Oil Filters Can Not Be Cleaned And Reused?

An oil filter reused after cleaning is not recommended. This is due to the special nature of the oil filter, the precision, and the complexity of the decision.
1, particularity:
Oil filter, also known as oil grid. The role is to filter out soot and gelatinous precipitates produced during engine operation under metal wear debris, dust, and high-temperature oxidized, lubricating oil to be cleaned, extending their useful life. Oil filters should have a filtration ability, small flow resistance, and long-life performance. Once unable to meet these requirements will result in irreversible damage to the engine.
2, precision
Cars on the oil filter requirements:
a, filter out all> 30 um particles
b, into the lubrication gap and reduce the wear and tear caused by particles (<3 um – 30 um)
c, oil flow in line with the demand of the engine oil
d, the replacement cycle is longer than at least the life of the oil
e, filtering accuracy to protect the engine, reduce wear requirements
f, dust capacity, suitable for harsh environments
g, can adapt to high oil temperatures and corrosive environments
h, when oil filter differential pressure as low as possible in order to ensure that the oil through smoothly
3, Complexity
By the oil filter paper, seals, and a variety of valves consisting of:
A: filter paper: oil filter paper for more demanding than air cleaners, mainly because of changes in the oil temperature ranging from 0 to 300 degrees, under extreme temperature fluctuations, the concentration of oil also changes accordingly, this will affect the flow of the oil filter. Quality oil filter paper to be able to at severe temperature changes, filter impurities while ensuring adequate flow.
B: rubber seals: high-quality oil filter seal with a special synthetic rubber, to ensure 100% no leakage.
C: reflux suppression valve: When the engine stalled, it can prevent the oil filter becomes dry; when the engine re-ignition, it immediately generates pressure supply oil to lubricate the engine.
D: relief valve: When the external temperature is lowered to a certain value or when the oil filter is beyond the normal period of use, the relief valve will open under special pressure, so that unfiltered oil flows directly into the engine, is the key engine protection in emergency situations.
Oil filters in the cleaning process, will inevitably damage the filter paper, seals, and other components, greatly reducing the effectiveness of the oil filter, so the engine damage. Therefore, not recommended oil filter be reused.
