    During my last two oil changes I've noticed the oil is very
    slightly mudded. Should I be concerned? It seems to be
    a very minor discoloration, the oil is just not brown but
    a tiny, I repeat tiny bit of muddy/flat milky shade.

    This is a 2000 2.2L Impreza with 26k miles. Has been
    driven mainly highway at high speeds. Oil is changed
    every 3500 miles. Coolant is nice and clear, haven't
    noticed it getting low, or anything, although I haven't
    been paying much attention to it, up till now.
    No overheating whatsoever.

    Please help, I would want to catch a possible problem
    before it gets costly, or something. Should I have it tested
    or just observe it for now?

    It's a bad sign. It could mean that the head gasket is leaking.
    Anyway, water tends to strongly reduce the bearings' load capacity thus
    damaging the crankshaft bearings.
    Just my 2 cents.

    Best regards.

    Before getting too excited why not get an oil sample analysis at
    www.blackstonelabs.com and see if you have a potential problem. ed
