No. Most conventional oil filters use a filter medium that is made of cellulose – typically wood fiber – and polyester fibers. Mobil 1 Extended Performance Oil Filters combine a mixture of synthetic micro fibers and natural fibers to produce a highly efficient oil filter.

The synthetic fibers in Mobil 1 Extended Performance Oil Filters yield the following key benefits:
A much more efficient filter, removing more particles per pass through the filter than conventional filter media.
Less resistance to oil flow, reducing the potential for the filter to restrict the flow of oil to your engine.
A larger surface area to trap more contaminant particles, allowing the longer service intervals.
