with the recent e core post i wondered what the progression of filter design has been, starting when spin on filters started to be made- when was that / late 60s??? up to the present - anyone got any pix of what the designs have been?
It might help us, along with lubeowners real world tests, see if the industry is moving forward or backwards or maybe sideways.
In front load clothes washer design the recent maytag neptune/whirlpool calipso class action lawsuits go a long way toward saying it a good idea but executed poorly.
Anyone got any historical pix since the 60s?- and remember they used to say change filter EVERY OTHER oil change? what technical study said to start changing every change (no its not the "dirty oil' not much of that there in the small filters (and they filter SO WELL the box says.
