Funny how seemingly innocent posts on the Discussion Forums trigger heated debate. There's some heavy traffic at the moment on a thread about oil filters. It's the old OEM versus aftermarket. Some folk recommend sticking with original parts while others argue aftermarket offerings are just fine. Of course, the issue is not limited to oil filters. There's generally a choice between OEM and non-authentic varieties for virtually every replaceable part - and strong opinions. Clearly, there's no right answer for everyone, and the decision will depend largely on cost and the level of risk. It's a balance between how much you can save by going with a no-name option, how crucial the part is and whether there's any real quality difference between the competing offerings. And for anyone about to change their filters, check out the differing opinions.
