Amsoil Oil Filters.. What issues ??

The OG Ultra leaf spring stamping was very smooth and flat, even though there was a fiber sealing gasket between it and the end cap. Plus the fit of the leaf spring was tight on the ID of the fiber gasket built into the end cap (another sealing area), so it essentially had a double sealing mechanism. Whoever is in charge of making leaf springs now for Fram and Champion Labs built filters is missing the boat and making junk.

Here's a photo of an OG Ultra leaf spring and the fiber sealing gasket built into the end cap. The sealing impression from the leaf spring can be seen in the fiber gasket. This is how a leaf spring should be sealed if you're going for maximum efficiency, which the OG Ultra was going for. Too bad it's no longer made to this standard anymore.

Now that makes complete sense.....the sealing gasket.
The metal to metal config in the Amsoil filter makes no sense whatsoever!!!
 
Fram Endurance is the "FE" part number series.

Amzoil filters are Fram XG filters painted and labeled for Amsoil at twice the price.
The aren't XG (Ultra) ... the Amsoil filters that are the same are Fram Endurance (post 43) internals in an Amsoil can.

Eeewww !!!
Yeah, you can see how poorly in the spring plate sits on top of the filter element assembly. That light is showing through, that area, which is basically the same on both sides, allows unfiltered oil to flow straight through, completely bypassing the filter material

Oh yeah I read about that stuff a year or 2 ago. They pretty much don't make it in any passenger vehicle applications and only a few diesel pickup truck applications. Pretty much all industrial stuff.
About all I could use is a 1.5x16 inch hydraulic filter on my long splitter and a 20x1.5mm fuel filter for filtering reclaim oil.
