Yesterday I watched a YouTube video comparing several popular brands of engine oil filters. Wix, Napa Gold, Bosch, Purolator and Fram. The mechanic doing the comparison cut the tops of each filter and took them apart comparing the components, construction and filter media.
Wix and Napa Gold came out on top with Purolator and Bosch considered acceptable. The Fram (the orange variety) turned out to be absolute garbage. He cut open two brand new Fram filters and found significant rust inside of both cans, The filter media was held together with glued cardboard. The paper filter media was flimsy and once taken apart was considerably shorter than all the other filters. The anti drain back valve was cheap and glued to cardboard and the internal spring was of a poor design compared to real springs found in the Wix and Napa Gold filters. BTW, I think Wix and Napa Gold are both made by Wix).
What the mechanic liked about the Wix/Napa Gold filters was:
- Sturdy construction
- Real internal coil spring used (rather than a sheet metal spring)
- Quality material and attachment used for the anti drain back valve
- Significantly longer & better quality filter media
- A metal strip used to fasten the ends of the filter media together which prevents internal leaking on the ends and makes for overall sturdier construction
About the only thing the mechanic found acceptable about the Fram's construction was the sturdy top plate, but all the filters had this (good thing for STP one of their filters wasn't compared. Ever look at the top plate on an STP oil filter?)
My only complaints about this filter comparison was that it didn't include more popular oil filter brands and comparing the entry level Fram to more expensive higher quality filters perhaps wasn't fair, but I came away thinking I'd rather used no oil filter than ever use a Fram filter and have rust and dissolved paper floating around inside my engine.
For my Fords I used to use Motorcraft brand oil filters, but it appears Walmart no longer carries them, so now I use Wix or Purolator Extended Life oil filters. I would also use Mobil1 or K&N oil filters, though they tend to be more expensive.
Watch the YouTube video and see for yourself.
