Petrol engines
AUDI prescribes changing the oil every 15,000 km and once a year. We consider this interval to be the maximum. When using the car exclusively in urban conditions, the oil should be changed after four months. When using single-season oil, it should be changed in spring and autumn.
The oil change should be performed with the engine warmed up to operating temperature so that all accumulated contaminants are removed along with the used oil.
Diesel engines
AUDI 80 TD produced before 6/92.
It is recommended to change the oil once a year if the mileage is no more than 7500 km. With a higher mileage - every 7500 km.
AUDI 80 TD produced since 7/92 AUDI 80 TDI
It is recommended to change the oil once a year if the mileage is no more than 15,000 km. If the mileage is greater, every 15,000 km.
To change the oil you need:
- a) motor oil of the appropriate specification,
- b) new gasket for the drain plug thread,
- c) a fuel filter corresponding to the engine type (056115561 G - for 4-cylinder engines, 035115561 - for 5-cylinder engines and 034115561 A - for six-cylinder engines, 028115561 - for diesel engines),
- d) a container for collecting used oil,
- d) key for removing the oil filter.
Oil change
1. Place the vehicle on jack stands in a horizontal position or on an inspection pit.
2. Remove the engine splash guard.
3. Place a container under the drain hole in the pan to collect the used oil.
4. Unscrew the drain plug with a socket wrench and drain the oil (see arrow in illustration).
5. Place a container under the oil filter to collect the oil.
6. Remove the oil filter with an oil filter wrench. If the filter is difficult to remove, pierce it from the side with a screwdriver, and then remove it with a screwdriver (see illustration).
Warning! Be careful. The oil is hot!
7. Lubricate the O-ring of the new oil filter with a thin layer of grease.
Caution! Do not lubricate the ring with oil. When checking for leaks, any oil that comes out may be mistaken for engine oil leakage.
8. Screw the filter in by hand.
9. Wipe the drain plug thread and screw it back into place, installing a new sealing ring.
10. Fill with new engine oil.
11. Start the engine and perform a visual check of the system for leaks.
