Re: color of oil

hehe...oil as mentioned should be oil colored. Amber (fresh), dark amber used and blackish to black (time to change oil). Milky color or Mocha = water in the oil.

Re: color of oil

Change it and then run it, see if the oil turns milky again. If not it was probably condensation. If it does then you have a leak some where. Head gasket, cracked head or cylinder, exhaust manifold leak or elbow leak, intake manifold leak etc. Check all your plugs, see if any water is getting into the cylinders.
