How does the FL-400S oil filter improve fuel efficiency?
The FL - 400S oil filter can adsorb and collect moisture in the oil and impurities generated by combustion, keeping the oil in good condition. Clean oil can form a better lubricating film, slow down the deterioration rate of the oil, extend its service life, enable the engine to maintain good lubrication conditions, reduce the energy loss caused by poor oil lubrication, and thus contribute to the improvement of fuel efficiency.
