Filter FAQ: Service Life, Replacement Cycle, Compatibility & Quality Issues

Many global filter buyers and fleet managers have many questions about filter selection and use. Here we sort out the most frequently asked professional questions to help you purchase and use filters correctly.

Q1: How often should heavy-duty filters be replaced?

Under normal working conditions, oil filters are recommended to be replaced every 10,000–20,000 km, fuel filters every 20,000–30,000 km, and air filters according to the dust degree of the working environment. Harsh environments need shorter replacement cycles.

Q2: Will aftermarket filters damage the engine?

Qualified OE-standard aftermarket filters will not damage the engine. On the contrary, unqualified low-cost fake filters with poor filtration precision are the main cause of engine wear.
