Place newspaper on the ground under the oil filter. Take the filter wrench and tighten it around the oil filter. Turn the oil filter counter clockwise to loosen it. Finish taking it off by hand and then drain the remaining oil in the filter into your metal pan. Empty the oil in your collecting pan into some plastic containers.

There is no need for concern. Aftermarket car parts are produced with the same machinery and materials as OEM and genuine parts. While the parts may have a few minor differences in look and feel, they basically do the same job. The companies who manufacture these aftermarket auto parts are credible. They legitimately buy the rights to manufacture those parts.
