Oil filters....which one to use?

...the 1970's the rage was to install toilet paper oil filters.

Actually, that started in the 30s when "bypass" (correct terminology) filters were the only type filters used on automotive engines. Not until much later did they (oil company shills?) convince the car makers to start using "full flow" filters, eventually instituting the now common "oil change" ritual. Let the oil get dirty, change it.

Oil doesn't wear out, it just gets dirty and suffers additive depletion. The top of my Duster's bypass filter, a Motorguard, containing a roll of toilet paper, can be seen in the lower right corner of the avatar.

Some things never change. The best way to filter motor oil (using a bypass filter with toilet paper element - cellulose) is one of those things.
