Installing an Oil Filter: Q&A

Engine oil filters prolong the useful life of the lubricating oil. Combustion is not without its byproducts, and it stands to reason that contaminant removal is a dirty job. Learning how to install an oil filter makes the at-home oil change possible. This Q&A can help.

Q: How often should I change the oil filter?

A: Plan on changing the oil filter every time you change the oil; the car's manual is sure to list an approximate time frame. Keep in mind that the use of high-efficiency filters stretches out the interval between oil changes. In this case, follow the instructions on the filter package.

Q: Are reusable oil filters really worth the investment?

A: If you can find a model that is compatible with your car -- and if its use does not void your warranty -- you should give this technology a second look. The Environmental Protection Agency explains that reusable oil filters back in 2001 offered appreciable savings to fleet operators in California and Minnesota. Since then, the residential market has picked up on the idea. Discuss the plan with your mechanic to be sure you get input on your particular car's make and model.

Q: My oil filter is stuck, what should I do?

A: An oil filter wrench can work wonders in this instance. This tool features an adjustable ring on a secure grip. When oil, grime, debris and sheer stubbornness keep the oil filter from budging, rely on this tool to loosen it. Clean off the filter with an absorbent paper towel to remove as much of the muck as possible. Adjust the ring of the oil filter wrench to fit your particular filter; rock the filter back and forth while twisting. Getting the oil filter unstuck in this manner is a snap. (Watch your knuckles!)

Q: Is it possible to avoid the mess on the garage floor when installing an oil filter?

A: You already know to put a catch pan underneath the car when starting this job, but did you consider filling it with shredded newspaper? This step cuts down on the splash mess from the engine oil that emerges as soon as the filter gets removed.

Q: Is there any kind of site prep required?

A: All you really need to do when changing out an oil filter is a good cleaning with a dry rag. Pay close attention to the plate on which the filter is mounted; it is common to have a bit of oil and grime buildup in the area.

Q: Should I tighten the newly installed oil filter with a wrench?

A: No! The oil filter wrench only serves to loosen the item; it is not used to secure the filter in place. The Second Chance Garage warns that over-tightening -- such as you might do it with the use of a wrench -- could actually result in warping of the filter itself. The result is a parts failure and mess of gargantuan proportions.
