I honestly don't know how you passed those ASE tests and still are so clueless about the way things work. Guess they must have let the standards come down in the last decade or so.
So go on using a known bad filter without a drainback valve and continue to think that a 5w20 and 5w30 are equal at operating temps, just not at startup. Obviously you must be correct. To hell with the hard data that says otherwise.
