Hello, I have a problem with the Astra h 1.8, 125km. I have it for a few days, I went on a trip of 600km, after some 400 the orange oil lamp lit up, so I bought and added 0.5 liters. After driving another 100, it caught fire one more time and again I poured 0.5 liter. At a standstill and the engine warmed, I gassed and did not smoke, while as stopped 4h I started it again and kicked black at high speed. I would like to emphasize that before starting I checked the oil level and it was ok. The car runs on synthetic and gas. Year 2005, mileage of 175 thousand km.
