I don't know if it's my imagination or not, but for some reason seems the brick has been running much quieter and smoother this last year, tho it has pretty much always run very well; it just seems it's even "better" now. Could it be at about 345k miles the motor is finally getting "broken in"?

I can't think of anything I've done to make it so much "smoother" except maybe due to my getting old(er),as we all are-------(I think :oÞ~~ ??) I'm driving more sanely now---¿--hmmmm----¿---ya think? My right foot does feel as tho some of the lead has broken off.
