Parts and consumables:
- motor oil;
- funnel;
- clean rag.
Note:
The manufacturer recommends using oil of quality level GM-LL-A-025, API SJ / SL or ASEA A2 / B2, viscosity grade SAE 0W-30, SAE 0W-40, SAE 5W-30, SAE 5W-40, SAE 10W -30, SAE 10W-40 (depending on climatic conditions).
Warnings:
Before checking the oil level after a trip, stop the engine and wait 5-10 minutes until the oil drains into the crankcase. Add oil of the same brand, viscosity and quality class as the one used previously.
The oil level in the engine crankcase should not exceed the “MAX” mark, otherwise leaks through gaskets and seals, increased oil consumption are possible. Check the level by setting the Opel Astra car on a flat horizontal platform.
The oil filler check is located on the cylinder head cover. The oil level indicator (dipstick) is located on the left side of the cylinder block in front of the exhaust manifold thermal screen.
1. Remove the pointer (probe).
2. Wipe with a clean cloth and reinsert.
3. Remove the pointer (probe) again. The oil film level must be between the upper and lower marks. If the oil level approaches or falls below the lower mark, add oil.
4. To add oil, turn the oil filler cap counterclockwise.
5. Remove it.
6. Fill in oil in the engine, controlling its level by means of the index. Before removing the pointer, wait 2-3 minutes to allow the oil to drain into the crankcase.
7. After the oil level reaches the required level, tighten the filler cap of your Opel.
