Before you begin
Change the oil in your Mk4 Jetta equipped with the naturally aspirated 2.0 liter engine. TDI and GLI models have different engines, and may have different procedures and requirements, such as oil capacity. For years, 3,000 miles was the correct interval to wait between oil changes, but that is no longer the case. Conventional oil in today's engines can easily last over 5,000 miles between changes. Synthetic oils are even more durable, maintaining good engine performance beyond 10,000 miles.
