I do my own oil changes, but my wife takes her Accord to quick lube
places. Almost every time she gets it back we smell burning oil, like
they got it on the exhaust manifold or something. Are these guys just
being sloppy, or is there something else going on? I don't get why it
happens every time, even though she takes it to different places.

Also, this last time, she got it back and had oil leaking (quite a bit).
I watched the dip stick and the level never dropped, even though at
least a half to full quart must've come out of there over several days.
Where was it coming from if it didn't affect the level the oil pan? Is
there an overfilling issue?

Thanks!
