What are the VW beetle oil specifications?

Most Volkswagen New Beetle models use a 5W-40 oil blend for engine oil. However, the specific type of oil required varies from model to model and year to year.

While most New Beetle models use a 5W-40 blend, the proper oil for an older air-cooled Beetle varies widely depending on the model year, origin and age of the car. The original Beetle was produced from 1938 until 2003 in several parts of the world. Mechanics often recommend using non-synthetic oils of 20W-50 grade for most drivers or 10W-30 grade for winter driving in colder regions, according to enthusiast website VW-Resource.
