Lubrication system, overview: Notes

WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 1999 Volkswagen Jetta, 1999 Volkswagen GTI, 1998 Volkswagen Jetta, 1998 Volkswagen GTI, and 1997 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: If large amounts of metal shavings or small metal particles are found in the engine oil, caused by wear of crankshaft and connecting rod bearings, thoroughly clean the engine oil passages to remove contaminants and help prevent further engine damage. Oil spray nozzles, oil non-return valve and oil cooler cannot be sufficiently cleaned and must be replaced. Oil level must NOT exceed MAX mark on dipstick. If this level is exceeded (too much oil) there is danger of damaging the Three Way Catalytic Converter (TWC).

Checking oil pressure, Oil Pressure Switch -F1- and 0.3 Bar Oil Pressure Switch -F22-, see OIL PRESSURE, OIL PRESSURE SWITCH, AND 0.3 BAR OIL PRESSURE SWITCH, CHECKING

OIL SYSTEM CAPACITY

Without oil filter 5.0 liters (5.3 qt.)
With oil filter 5.5 liters (5.8 qt.)

Engine oil specifications (see Owner's Manual)

The following terms must appear on the oil container singly or in combination with other designations: VW 502 00 or VW500 00 or VW501 01, ACEA A2 or ACEA A3, or API-SJ or API-SL.

Engine oils are graded according to their viscosity. The proper grade to be used depends on existing climatic or seasonal conditions.

The original oil has a viscosity grade of SAE 5W-40. This oil can be used over all temperature ranges for normal driving. If engine oil viscosity grade SAE 5W-40 is not available, use SAE 5W-30.
