Must have something to do with oil viscosity and flow restriction in the filter, though the bypass must be open at WOT at 5000+rpm.

Idle-3500ish is probably my operating range. Just guessing tho', don't have a tach. ENEOS 5w-30/Ultra-8 made the most noise, but still not that bad. Amsoil HP 5w-30/Wix made Amsoil Ea filter was a small improvement. Maybe it was that space wasting Wix bypass valve? Pennzoil Platinum 5w-30/PureOne made an even bigger improvement.

well, now i'm DEFINATELY glad i chose the Pennzoil Platinum. i had found an ENEOS distributor nearby(they only sold them in cases of 8 quarts?), but decided to save a few bucks based on the reviews i've read on here. like you said, it does seem to idle a little quieter(maybe it's my imagination), but mainly i made the switch because my car isn't just transportation TO my job - it IS my job! i'm getting ready to put the same thing in the wife's yaris as soon as i see a sale on it somewhere.
