Car makers worry about their reputation, but also are in business to beat the competition. It is becoming a norm to advertise low maintenance cost, which is then disclosed as an annual estimate. Hence, it is considered that the oil filter is replaced every other oil change. Which in turn, reduces the cost of the vehicle maintenance. On the other side of the river, the oil filter manufacturers suggest that the filter is to be changed every time you change the cars oil.

Now, which word should you take for granted!! Cars in houston says lets research it.

·         Cars in houston interviewed many mechanics.

o        Most agreed on the fact that the the every other oil change is a false economy.

o        Most mechanics highly recommended changing the oil filter every oil change. This was back up by their experience, and science.

·         Car engines today use a filtration process called "full-flow”.

o        Every drop of oil goes from the reservoir to the engine passing through the filter first.

§         This means, the oil filter is the primary defense line to the engine's crankshaft, and cam bearings. It absorbs and filtrates against abrasion and premature wear to the engine

§         The oil filter removes unwanted solid entrants to the system. Entrants that can damage the bearing, journal and cylinder wall surfaces once they reach the engine such as

§         Dirt

§         Carbon

§         The filter.

Over time, the filter accumulates dirt that has been trapped, until it reaches a point where it is possible for oil passage to be obstructed. The good and bad news in one, is that filters are equipped with a bypass valve. This is to prevent from catastrophic failures due to improper lubrication, which will allow the dirty oil to pass to cause accelerated wear.

Cars in houston concluded that since filters cost less than ten dollars a piece, then you should replace the oil filter every time you change the oil. The worst case scenario would be that you lost a 100 dollars over the life of your car. On other hand, if you neglect changing the oil filter you are looking a possible damage that could cost no less than 1200 dollars.
