Excess engine wear at startup and at full operating temperature. Use only the weight oil that is recommended by the manufacture.
Yes there is no difference. I would however recommend you use synthetic oil in a motorcycle especially an air cooled one.
yes it will. use motorcycle oil only
it will seize up
Full synthetic motorcycle oils can and regularly do have additives to make them safe for use in vehicles with a "wet" or "oil bath" clutch. Standard synthetics tend to generate excessive slip in a wet clutch. To accurately answer the question. Yes you can run synthetic motorcycle oil in your car. However I would advise against doing the opposite.
If the engine was void of any oil it would seize in the matter of minutes and yes the car would not work.
A used motorcycle trailer would brought from a used car lot. These can come at a cheap price and a good deal. It would also come in a good condition with a can of oil.

If your car's oil is changed on a regular basis at or around 3000 miles and you happen to miss that interval once in a while, nothing bad is going to happen. If you continuously are slow to get your car's oil changed, you can expect to cut you engine's life short.
