Yea they take synthetic oil, make sure you don't do otherwise cause you can not mix different oils!
The 1974 VW Super Beetle engine oil capacity is 3.5 quarts. Three quarts of oil will be in the engine and one half quart of oil will be in the oil filter.
Double check your owners manual, I can't remember what spec is required for 2003 VW's. But it will definitely be a 5w40 oil
A 2002 Volkswagen Beetle with a 2.0 liter engine should use synthetic oil. The oil weight for this vehicle should be 5w-40 or 5w-30.
Gas: 5W30 synthetic, gasoline-rated oil. Diesel: 5W40 synthetic, diesel-rated oil.
It is not required. You can use conventional or synthetic oil.
