Turn the motor by putting a wrench on the power steering pump pulley nut. I assume the motor isn't stuck.

the oil is not the problem. but i would put oil in it just because i would be afraid i would forget later and start it up empty.

Whats the history of this engine - how long in hibernation? Never try to turn the motor from the camshaft bolt, stick with the crank or power steering pulley and it should turn over.

i would stick to the crank pulley bolt... less stress put on the power steering pump and its safer. also when doing an overnight oil change either put a note on the steering wheel or disconnect the batter and put a note on the battery ... two fail safes for the second method

If you've got a stick shift, put it in 4th gear, release the parking brake, jack up a rear wheel and turn the rear wheel by hand.

You should be able to turn a 240 engine by turning the fan with one hand while tightening the belt with the other hand. If that doesn't work try the crank bolt. I had a 240D engine lock up one me for seemingly no reason. Unlikely that is the case with your engine however.
