Fil­tra­tion

Car Mechanics (UK) - - Engine Oil & Lubrication -

As when buy­ing oil, sac­ri­fic­ing qual­ity for cost on fil­ters is a false econ­omy, es­pe­cially as there are many coun­ter­feit items on the mar­ket. Buy fil­ters from a qual­ity sup­plier, us­ing well-known brands that are known to equal the orig­i­nal man­u­fac­turer qual­ity at least.

Un­like en­gine oil, there is no spec­i­fi­ca­tion that you can check, but trusted brands in­clude Bosch, Coop­ers­fi­aam, Fram, Mahle, Mann, Pur­flux and So­gefi, as well as af­ter­mar­ket spe­cial­ists such as Blue Print and febi bil­stein. Main dealer-sup­plied oil fil­ters can be sur­pris­ingly good value, too. While low-cost al­ter­na­tives may look the same on the out­side, they may boast less fil­tra­tion medium, which may be made from an in­fe­rior and cheaper ma­te­rial, as well as poorly-made can­is­ter spin-on type fil­ters omit­ting anti-drain flaps (the re­sult of which is in­creased en­gine wear on start-up) and in­ef­fec­tive, or miss­ing, pres­sure valves.

Fil­ter man­u­fac­turer, Mahle, has con­cerns about poor-qual­ity oil fil­ters made of cheaper, low-grade ma­te­ri­als, such as an in­ad­e­quate, or poorly-folded, pa­per fil­tra­tion medi­ums. Mahle also dis­cov­ered metal burrs and shav­ings within the tested spin-on fil­ter hous­ings, due to in­ef­fec­tive ma­chin­ing and a lack of qual­ity con­trol, as well as an ab­sence of glue to re­tain the fil­ter body to the metal in­ter­nals.
