How many miles do you have on your 5000? I've been toying with the
idea of switching to synthetic in my 100Q for a while, but I've been
told that it's a "bad idea" once you have more than a few thousand miles.
Is this not true?

For dinosaur oil, I recently discovered Sunoco Ultra oil (thanks to
a $0.79 sale at Auto Palace). It may not be synthetic, but it made
a BIG difference.

Does it sound like a spring creaking? I have the same sound, and I'm at
a loss for what to do. I looked around for some piece of spring rubbed
clean, but found nothing. I think it may be the springs squishing
around in whatever holds the body to them up top. Oh well....

Once again, my 100Q does this, too. My wife's 20V 90Q doesn't, I think
because it idles higher (950 vs. 700 RPM). I think it may just be some
kind of resonant frequency of the 5000/100 body at that RPM. I may try
to adjust the idle, but that is not easy to do. How I long for that old
carburetor screw you could just twiddle  ;-)
