Tip of the Week
The oil filter serves as the lifeblood for your engine. It is important because it cleans the oil and is capable of filtering high volumes of oil with relatively low restriction. How do you know which filter to choose and what are the differences between styles? Royal Purple has provided the following information to help you decide.
- The shell is the outside casing you see when the filter is installed. It keeps your filter safe during the wear and tear on your vehicle, and protects it from punctures.
- The media is the filtering component. Depending on the level of filter you chose, media can be described as a maze of cellulose, synthetics and/or microfibers that remove the harmful debris from your engine oil.
- The core is the part of the filter that helps the filter keep its shape and prevents it from collapsing under extreme pressure. It is inserted inside of the filter media and can be made of a variety of materials.
- The base plate is the threaded component of the oil filter. In addition to providing the threaded attachment for the filter, it directs the oil flow through the filter.
- The gasket is the rubber ring that seals the filter to the engine's oil filter base. This gasket is typically made of flexible rubber.

Q: I am planning on replacing the brake pads on my 2005 Cadillac, CTS 3.6 engine and am looking for your recommendation for a particular brand and type (ceramic or semi-metallic). I do not plan on replacing or having the rotors turned down as long as they do not have any ridges. My car presently has 23,000 miles on it. The original equipment pads leave a large quantity of brake dust on the mag wheels.
A: Unfortunately brake dust is a common complaint form both import and American vehicles. Import vehicles usually have a black dust and American vehicles have a rust brown color dust always on the front wheels. There are no dustless brake pads on the market to date. I would recommend either the factory GM or the Hawk brand. As long as there is no brake pulsation, the rotors can be left alone.
