It should be noted that 1951 Kaiser and Frazer automobiles came with an oil filter as either standard equipment or as part of an accessory group. Regarding Henry J and Allstates, some people swear by their effectiveness, others swear at them.
1951-55 Kaisers came with a type 1/2 filter as standard equipment. This was an oddball where the entire metal canister was sealed (no replacement element). When you had to change filters you literally disconnected the two oil lines and put on a new canister. Problem now is that these filters went out of production in the 1980's. They were also used on 6 cylinder Chrysler Corporation cars into the late 1950's & there are some of the Chrysler parts filters (they are black in color) still around.
However, as you will find in KFOCI HANDBOOK, when the 1951 Kaiser went on sale, the factory issued a memo suggesting that dealers sell retail car buyers the replacement element filter unit and replace the 1/2. The memo states that the swap pays for itself after 5 oil changes because of the cost difference between the element compared to the much more expensive type 1/2 canister. The part number they refer to came either as a Purolator unit (uses P70-ff element) or Fram unit.
