You don't need to change the engine oil for winterizing unless you suspect you've got water in the oil. I would normally do an oil and filter change in the spring with a tuneup of plugs, cap, rotor, points & condenser. If you are set on changing the oil then a pump is needed to draw it up the dipstick tube. I use an electric one mounted on a 3 gallon bucket but there are manual pumps you can get for little money. You have to run the engine for a while to heat up the oil which makes it easier to take out through the dipstick.
