How to Choose the Best Detroit Filters

23518532 Detroit FilterDetroit filters can keep your car in good running order by removing contaminants from your engine oil. If your engine is constantly exposed to these contaminants, it can be damaged. Thus, using the right filter can save you money by keeping your engine in good running order so you won’t have to spend on repair and maintenance. In particular, not filtering your oil can cause engine problems such as broken cylinders and damaged oil pumps as bits of metal that have chipped off the engine recirculate through the oil.

Oil filters used with diesel fuel in particular, have to be chosen carefully because when diesel is not burnt completely, it leaves behind residues of sulfur dioxide and carbon in your engine. When you’re choosing a filter for use with your diesel engine, it must be OEM replacement parts from reliable suppliers or those recommended by the manufacturer to ensure that all the corrosive particles are removed from the diesel fuel.

Here are the three different types of Detroit filters based on the type of design they use:

  • Mechanical. This type of oil filter uses fibers that have been pleated to trap the contaminants in the oil so that they won’t get into the engine. Over time, however, the filter becomes clogged and it is no longer effective as it prevents the oil from passing through. Before this happens, the filter needs to be changed.
  • Magnetic. This design uses electromagnets to catch the iron particles when the oil flows through the filter. Since a physical filter is not actually used, magnetic filters do not need to be replaced. Of course, they will need to be periodically cleaned in order to ensure they remain effective. One drawback of this design, however, is that dirt can get into the engine since there is no physical filter to trap it. However, there are add-on magnetic accessories that snap onto the side of other filter designs and make them more effective by trapping metal particles on the side of the filter.
  • Centrifugal. This filter uses an internal centrifuge to trap contaminant particles by creating centrifugal force to contain them. The oil flows through the spinning centrifuge, the dirt and metal particles are trapped on the filter walls. There are two parts to the centrifugal filter, a housing chamber where the oil enters, and the actual physical filter which spins to create the centrifugal force. As the dirt and other particles build up in the filter, however, it needs to be replaced as it will eventually stop spinning.

When choosing OEM replacement Detroit filters for your car, experts advise that you get the model with the biggest diameter that you can find, since this will allow more oil to enter your engine to lubricate it as well as having a bigger filtration area. In addition, with a bigger filter, the device can filter more oil at a lower pressure, which allows less oil to get into the engine that is unfiltered. Also keep the clearance of the filter in mind, since if it dangles too low below the oil pan, it might be dislodged by a speed bump or other obstacle, which would cause the total loss of oil.

When you’ve bought a new filter, fill it with oil before installing it. Wait for a few seconds while the filter is absorbing the oil. Once the oil disappears, add more oil until the filter stays full. This will help prevent the engine from experiencing a dry start. You should also run some oil over the gasket of the filter since this will make it easier to install. And wipe the surface where the filter is to be placed before you install it.
