The automotive repair industry recognizes that 80% of engine wear comes from the moment of cold start. In low-temperature environments, the oil is viscous and has poor fluidity. The protective effect of the oil filter is crucial and directly determines the degree of engine wear.
In winter, when the temperature is low or the vehicle is parked overnight, the viscosity of the engine oil increases significantly, the flow resistance increases dramatically, and the permeability of ordinary inferior engine filter materials is poor, which easily leads to oil blockage, causing the engine oil to be unable to be quickly delivered to various lubrication parts of the engine, forming a dry grinding window period of several seconds, and continuously wearing down precision parts such as pistons and crankshafts.
The high-quality and long-lasting machine filter has been specially optimized for low-temperature adaptability, with better permeability of the filter material and lower low-temperature resistance. It is also equipped with a precisely tuned high-sensitivity bypass valve. When the cold start oil becomes viscous, the filter element flow is blocked, and the pressure difference between the inside and outside increases, the bypass valve can be instantly opened to open the emergency oil circulation channel, ensuring that the oil is supplied in seconds and completely preventing dry grinding damage.
At the same time, high-quality filter materials adopt low-temperature resistant technology, which will not become hard or brittle due to low temperature, and always maintain stable filtering performance, accurately intercepting the condensed gum and fine impurities in low-temperature engine oil.
Long term use of high-quality low-temperature adaptive filters can significantly reduce cold start wear and effectively extend engine life, especially suitable for car owners in northern low-temperature areas.
