the drain plug is in the middle of the car at the rear on the ribbed underside of the engine case.there is one center plug and 6 smaller nuts in a circle. these nuts allow you to clean the strainer .The capacity of oil is 5.3 pints(2.5 litres)I do not know the benefit of syntetic on this type of engine.I am only the owner of a'71 bug for a few months my engine is being rebuilt.One of the other bug owners might be able to tell us about the synthetic oil in an aircooled motor.I am curious. 9(

Personally I would not use a synthetic oil in this engine as these engines were designed when synthetic oils were not even around. Use a 'decent' 20w50 mineral oil and she will be happy as cheese. Besides these engines are known to 'use' oil aswell as leak a little.

You may not have a center drain plug. You should always remove the entire plate and replace the gasket after inspecting the strainer screen for metal and debris. Synthetic oil is fine, but the first time you put it in the engine, you should run the engine up to normal temperature and then drain out the mixture and refill with synthetic. The engine holds a lot of oil in the cooler and pump that will not drain out.
