Oil filters 101

[David Maxwell]

...as evidenced by the parts manual, repair manual and this photo from the Plymouth Dealer Data book published by Chrysler Corp. You can see the oil filter housing peeking up just over the ignition coil. The data book gives all specs on the standard oil filter "Sealed-unit type with radial-type element developed for use on Army and Navy airplanes. The filtering principle is called Micronic Filtration".

It would be interesting to find out for once and for all which years/models had oil filters from the factory.

I know that in 1933 the original PC ("Plymouth 6") and the later PD ("Deluxe 6") came from the factory with filters. Not sure about the PCXX ("Standard 6").

I understand that in the later 1930s the Standard/Business/Roadking models did not have oil filters while the DeLuxe models did.

Would that have been true in the P15 era: The low end (Deluxe) without filters but the high end (Special Deluxe) with filters?

I think all shown are period correct.

May have been installed by a dealer, who got them from someone

besides the car maker.
