Not necessarily. 4-cycle engines typically use something around SAE 30 motor oil which can sometimes be used in a car, but is much thicker than the multiviscosity oils used in cars. A car (dependant on manufacturer specs) would use something around 5W30 or 10W30 for older vehicles. Check your owner's manual to be sure what you need.

Yes you can consider using 5w30 oil in your motorbike engine, but it depends upon season...
Yes you can use 5W20 oil instead of 5W30. One is just thicker then the other. The 5W20 is better in the winter and the 5W30 is better in the summer.
