You should be using 5w-30 oil. Unless you are somewhere tropical.
Yup, soobys do tend to knock when cold. Mine has about 180,00 miles on it and knocks when cold. We have one at work that has been knocking for the last 90,000 miles(it has done 240,000). Nothing to worry about unless it knocks all the time or is severe.
BTW, it's easier to help out when full details are given about the car in question: year, model, mileage, engine, etc. :)
