Therefore, relief is the key to protect the engine in urgent circumstances. Moreover, with cement instead of adhesive, it has the greater danger. Using low-quality adhesives, and little amount, not oil proof, not firm adhesion, bonding at the short circuit caused by the filter; or filter the seams with staples connection, short circuit can not be sealed, so that a large number of harmful impurities into the engine, reduce engine life.
Installation:
Drain the old oil
b) Loosen the screws, remove the old oil filter
c) Rubbed a layer of oil in the new oil filter gasket
d) Install new oil filter device and tighten the screws
The impact of poor quality filter on the engine

1. Using original parts are best, in order to avoid unnecessary economic losses.Using ordinary rubber to replace oil rubber, in the course of use or because of internal seals failure's formation of internal filter short circuit resulting in early engine wear, life or external seals reduce as swelling deformation, causing the oil strainer outside seal ring be out, a large number of oil spills in a short time, the engine has bush-burning, axle, suffered serious damage.
Relief: Only in high-quality oil filter. Filter cover, central pipe, outer skin and other metal parts, do not have anti-rust treatment, which result in corrosion of metal impurity, the filter becomes a source of pollution. High-quality oil filter's filter paper can change under severe temperature, filter impurities, to ensure adequate flow. When the engine is off, it can prevent the oil filter to dry; when re-ignition engine, it immediately produces pressure, supply lubricating oil to the engine.
Return valve inhibition: only in high-quality oil filter.In the course of absorption, due to the central tube deflated, broken and plug the oil filter, resulting in insufficient engine lubrication; or seams' reliability is poor, the process of using bite mouth opened, resulting in a large number of oil leaks in a short time, and bush-burning, holding shaft.

Oil filter central pipe materials using thin replace thick, strong is not enough.Therefore, the cost of poor quality filter is great.Using the low-cost filter paper as filter element, because of its large pore size filter paper, low filtration efficienc, the engine will not effectively filter out harmful impurities, causing early engine wear. We suggest the users must be careful when replacing the filters. Air filter outer skin parts' welding using welding spot replace welding seam, can not guarantee seal, and will form a short circuit. When the outside temperature is reduced to a certain value or when the oil filter out of the normal useful life, the relief valve will open under the special pressure, so that unfiltered oil to flow directly into the engine.

Filters paper: oil filter's requirements on the filter paper are higher than the air filter, mainly because the oil temperature is range from 0 to 300 degrees, in severe thermal shock, the oil concentration also changes accordingly, which will affect the oil filter traffic.

Rubber seals: high quality oil filter's seal is a special synthetic rubber, 100% guarantee of the oil spill. Despite the result, oil impurities will enter the engine, but not compared to the engine oil losses, it is much smaller
