How does the W67/2 oil Filter improve fuel efficiency?
The internal structure design of the W67/2 filter takes into account the balance between filtration efficiency and oil flow. It can maintain a smooth oil supply channel while filtering impurities. If the oil filter is blocked, the oil circulation will be hindered, and the oil pump has to consume more power to pump oil, which indirectly increases fuel consumption. The W67/2 avoids excessive accumulation of pollutants inside, reduces the working load of the oil pump. Moreover, its internal check valve can prevent the oil inside the filter from draining when the engine is turned off. When the vehicle restarts, it can quickly build up pressure to deliver oil, reducing dry friction inside the engine and avoiding the engine consuming extra fuel due to unstable initial lubrication.
