Always refer to your owner's manual and also gauge if your driving habits are considered "severe".
This type of "severe" driving requires more frequent oil changes as recommended by the Car Care Council. For less wear-and-tear on the engine in colder climates (sub-zero driving temperatures) ask your FULLSERV Service Technician if oil weight should be changed to accommodate these conditions. Your Mom & Dad would probably suggest simply moving to somewhere warmer; but in reality, your FULLSERV Service Technician will have a more cost-effective and easier solution.
THE OIL FILTER consists of a high-strength steel housing and contains various filter media. An anti-drain back valve prevents oil from running out of the filter when the engine is off. Today, oil filters have a convenient spin-off design that makes removing and installing a new one easy. The OIL FILTER removes contaminants from the oil and allows oil to flow freely through the engine. When the oil filter becomes restricted or clogged with contaminants, oil will flow or bypass around the filter. While the "bypassing" is a safety mechanism, you will never want to let your oil change go so long that the "bypassing" occurs. A good maintenance practice is to change the oil every 3000-5000 miles.
