Contamination constantly accumulates in the running engine: fuel combustion products, metallic dust, insoluble additives (e.g. sulfur compounds), and the task of the engine oil is to keep the engine clean and, consequently, its performance. Periodically used oil is changed to fresh oil and at the same time, the oil purifier is changed.
Before talking about the purpose of the oil purifier, it is important to remember the functions of the engine oil itself.In addition to its direct function of protecting parts from friction, good oil also washes the engine, taking over mechanical and organic impurities and acidic components that occur when the engine is running. To ensure cleaning properties, manufacturers add alkaline additives to the oil, which prevent excess impurities from settling on metal parts in the form of lacquer, sludge, and soot. All these particles remain suspended in engine oil and oil filters are installed for their screening. The engine oil, moving through the engine lubrication system by means of an oil pump, necessarily passes through the purifier in which all impurities and suspensions remain. This is a necessary condition for normal operation of the engine, otherwise, it will quickly grow up with products of combustion and will fail.
As a rule, in modern cars, the oil element is installed on the oil pump housing. The thread on the center hole of the filter corresponds to the thread on the hollow shaft to which it is screwed until the seal fits snugly into the pump housing. The uncleaned oil flows through the small holes, passes through a purifier corrugation made of special paper or synthetic material and the cleaned oil exits through the center hole. In a quality element, the movement of oil is not disturbed: to prevent oil outflow during parking, there is a non-return valve, the special filter paper is installed in a metal clip to prevent crushing (and often reinforced with metal mesh on the outside), and the joints are securely sealed.
The casing and lid are made of strong steel with anticorrosive coating, and the rubber elements do not deteriorate from oil and high temperatures.
Is MicroGard a good filter?
MicroGard material has the best ratio of voids, which are important for oil flow, and a large number of purifier strands. It is most likely that oil passes through this material faster than others. The filter “paper” of this filter is thin, which means that the oil flow will be easier to overcome its resistance. It should also be noted that MicroGard seems very similar to the WIX and the original in terms of functionality.
Does WIX make MicroGard filters?
WIX is a well-known American manufacturer and a very successful distributor of high-quality filters for motor vehicles and special equipment. It is a part of the “Affinia Group” and financial organization Cypress Group. At present the company has 13 plants located in the following countries: Ukraine, USA, Venezuela, as well as Poland, Mexico, and China. All sold production corresponds to rigid standards ISO/TS16949/14001.
In catalogs, WIX motorists can find already 6 thousand models of filters. All these products are of very high quality, which motorists choose for its reliability, availability and pleasant price. The American company also belongs to the official suppliers of several car dealers, including Toyota, Volkswagen Group, Nissan, Suzuki, and Opel. In Europe, the most common WIX filters are from Polish and Chinese plants.
Buying WIX filters, the car enthusiast gets almost a perfect replica of the original filters (especially filters for diesel cars). Practice shows that American-made filters are slightly better than filters produced in factories in other countries from the list. An assortment of WIX car enthusiasts will be able to find and know-how promoted on the market only by this company, such as special flow filters, Spin-flow and special dehumidifiers Aqua-tech.
WIX is said the Microgard air filters and IIRC many are off-shored. Less popular OPE filters, as well as fuel and transmission, are offshored too.
Who makes MicroGard oil filters 2018?
MicroGard is made by Purolator, which is obvious when looking at the backplate design being composite steel/aluminum. They are Purolator right down to the center thread size stamped into the backplate. They are definitely not WIX/NAPA Gold.
Is WIX better than MicroGard?
The WIX and MicroGard are similar in construction but have different media. Most have the bypass/ ADBV combo design too. You can look for a WIX cartridge filter and compare that to the MG equivalent. The media color is different, but the pleat count is nearly identical. They should be able to do 3k-5k without any issues at all. The only difference is that the MG used a rubber adbv and the Wix had a silicone adbv. Also, most MG filters are 50% cheaper. Overall, Microgard is a “value” level WIX, and filters just as well as the more expensive one.
