OEM filters VS Aftermarket

[Infinitiguy19]

How much can a OEM Fuel filter trap in Grams VS a After market filter?

How much more efficient is a OEM fuel filter than a Aftermarket one, in microns?

I have heard that Purolator makes OEM filters for Ford (Unconfirmed).

I took apart my M1(-208) engine oil filter and my OEM (Original?) transmission filter (Internal) and will have pictures up soon. I did not cut them open but rather used a great tool to peel the metal back.

In 1956 Ford started offering one of the first "commercially viable" spin on oil filter for Ford, Mercury, Thunderbird, Lincoln, and Continental. Continental was a separate division in those days with an up-market product from Lincoln. The first "twist of a wrist" spin on filters were made for Ford by Wicks. The following year, other OEMs began following suit. I believe all 57 Fords had spin on filters. I remember the Chevy 283 engine (up to 67) used a cartridge filter named Purolator P-141. Each time I bought a Chevy with a 283, I would quickly install an adapter to use a spin on oil filter.

I have seen references where MotorCraft oil filters are purportedly made by Champion Brands today. Also, I've seen where the Mobil-1 filter is made by Champion Brands. I've seen a cut away of the Wal*Mart SuperTech oil filter and it also has a distinctive Champion Brand manufactured look about it. A while back I found a video where some guy was screaming obscenities into a you tube video as he cut open a variety of oil filters to find many were clearly from the same manufacturer - that being Champion Brands.

Fram made an early attemp to manufacturer a spin on filter for Crosley in the early 50s that failed. It is not considered in true lineage for today's spin on filters.

Meanwhile I have enough PurOne and Wix made oil filters stocked up to easily last 3 to 4 years for the Nissans and Hondas..
