Motorcycles use either a wet clutch or a dry clutch. The wet clutch is what necessitates the biggest difference in engine oils between cars and motorcycles. The reason is that a wet clutch sits in the same engine oil as the transmission and crank case, and most of the time, the crankcase and transmission is all one unit without any partitions. Typical car engine oils have friction modifiers in them, and these modifiers are a huge range of chemical compounds designed to help the oil do its thing. That's fine for a car or even a motorcycle with a dry clutch, but friction modifiers will ruin a wet clutch. So if you have to buy motorcycle oil, make sure to read the back label to see if it says its safe for wet clutches. If you're not sure if your bike uses a wet or dry clutch, you'll be safe either way buying an oil safe for wet clutches. Always consult your manual or dealer, though before pouring anything into your engine!
yes it will. use motorcycle oil only
Yes there is no difference. I would however recommend you use synthetic oil in a motorcycle especially an air cooled one.
hd motorcycle
Each states driving laws differ but everyone I know of requires a motorcycle licences or endorsement to be legal.

10w30 four stroke motorcycle oil. do not use car or truck oil!
one quart 10w40 four stroke motorcycle oil. do not use car or truck oil!
one quart 10w40 four stroke motorcycle oil. do not use car or truck oil. 10w40 4 stroke oil is car & truck oil which are also 4 stroke engines. You can use the very same oil you use in your car and truck as long as you use the correct weight which is 10w30 and not 10w40. There is no difference in so-called motorcycle oil and car or truck oil. I do however highly recommend you use full synthetic oil in any air cooled engine.
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.
There is no such thing as motorcycle or car oil. They are one in the same. They are both 4 cycle oils. They may be labeled motorcycle oil but they are the same as the oil used in cars. As long as you use the correct weight you are using the correct oil. I highly recommend you use a full synthetic oil in your air cooled 50 cc engine.
The same as the filter in a car engine... to screen out impurities from the oil in case it damages the engine.
Car oil is not meant for the clutches in an ATV engine. You should get oil that is designed for motorcycle or ATV wet-clutch engines. It will say it right on the front of the bottle.
