John, I subscribe to the "Mahle is best, it't the superior anti-drain
valve spring pressure that makes the differencs and keeps the oil in the
galleries of the engine rather that letting it bleed down and out"
theory. Can't really give you definitive proof, only to say that my
engine does much better on the Mahle or Mann filters than others.
I don't really know why the system on the 2.1L is so twitchey/bitchey,
but I really do take a lot of steps to avoid the valve clatter
syndrome, like the Mahle filter, the 15W50 Mobil One Synthetic oil, the
MMO into the oil periodically, and religiously change the oil. My
machine clatters loudly and lets me know clearly when I have waited to
long for an oil change. I just keep up the special steps that it has
required of me, and that takes care of it 99% of the time.
Regards,
John Rodgers
