I have always had a little piston slap at idle, no big deal, and I have always run Chevron supreme with a NAPA gold filter. Well, after reading that really long thread about which oil to use, I decided to change to add MMO, use rotella T, and changed to mopar filters, plus I changed my motor mounts and oil filter adapter O-rings at the same time (don't know if it matters, but I'll thow it in there anyway). Well, right afterward I noticed the piston slap getting much louder at idle, and now I can hear it at all rpms! Now that it has been in there for a while it comes and goes, and it is starting to happen less often, even at idle. Any idea WTF is going on? Should I quit using MMO for the next oil change?
