What oil filter do you run and why

I have a few comments to share on filters.

1. Back in the mid 70's I worked for a company that made thermostats, radiators, oil coolers, etc for all three of the Big Three plus virtually every aftermarket brand. We also had a very extensive engineering lab which I ran and would do contract testing for most anyone that wanted to pay. We were approached be Lee Filters (remember them?) to do comparison testing to the other leading filter brands (they wanted it for marketing purposes). I recall Fram, Purolator, Baldwin, Hastings but there were many more in the test. We performed all the SAE tests of the time plus some others we schemed up our selves. The overall conclusion of all that testing was there was no difference. I realize that that 35 years ago but it is just something I want to share.

2. FRAM sells far more filters than everyone else combined under the FRAM name plus many others including both Mopar (lately they look like Purolator though) and Honda names. Just by shear numbers you are going to hear of more failures than other brands but could very well have a lower failure rate. I don't know what their failure rate is but you do have to keep that in mind when you listen to internet horror stories.

3. All of the pictures you see floating around on the internet showing this filter is better than that filter are just opinions. The physical appear has little or no baring on how well a given filter actually filters oil.

4. A good friend of mine was the Quality Manager at IPC Global Solutions. They make oil/air/fuel/cabin filters for virtually every filter manufacturer selling product in the US. All of their filters are made in China or Taiwan. They provide a co-manufacturing service for most of the manufacturers where they build the low volume part numbers or provide additional capacity. So that Wix or NAPA or Purolator or Fleet Guard may actually have been made in China.

5. Last comment; Don't put to much weight in what you hear on the internet, do what you are comfortable with. FWIW, the only filter I have personally had fail in my 40+ years of driving was a Wix that leaked at the seal where the can was attached to the base. I will still use them though I mostly use Motorcraft (Purolator) these days because they are very affordable.


Still the most intelligent comment on this post to date. Pay particular attention to para #3. He actuually does not put any filter down. Unbiased?
