Kind of long, however, well worth it B) oil filter pressure drop

cool, that's why I always use OE filters (i.e. toyota/lexus)

Those are great, however sometimes costly and the dealership is not always open. Believe it or not the walmart supertech filters are some of the best out there for the money charged, B)

That thread is mostly a lot of hot air and babble. A few terms: the pressure relief valve is normally in the oil pump itself, and limits the amount of oil pressure when the engine is hot, and usually cannot limit the oil pressure fully when the engine is cold due to thick oil. The bypass valve is normally in the oil filter, but GM used an external one, built into the oil filter mount for the small and big block V-8's. The pressure relief valve floats back and forth when limiting system pressure, the bypass valve will open when the filter becomes blocked to prevent loss of oil pressure in the engine, as the filter is between the pump and the oil passageways of the engine. The bypass is not intended to open under cold start conditions, unless the engine has a high viscosity oil and is very cold, say a 50W straight grade being used up north at -30F. If the bypass does open, unfiltered oil, and some of the already captured particles in the filter, will be circulated in the engine.

The best filter is the OEM filter, and if you are ever looking for warranty service on an engine, the first thing the dealer will look for is their filter. Whether it made a difference or not, they will claim it did, and make your life much tougher in terms of a successful claim.

Of course if saving two or three dollars every oil change is important, buy a crappy oil filter. My view is that it takes hundreds of dollars of gasoline to run the engine long enough to require a ten dollar oil filter change. Big deal.

I agree that the best oil filter is the OEM , however many people don't buy OEM they just buy whatevers the cheapest or whatever is the most expensive or whatever the lube place down the street installs and that's not always the best filter.

This final study kind of puts them all into perspective
