Hi , my omega has now run 240000 km and what has been done exactly by the pre-owned I know net so exactly .. now I want to keep the car definitely at least 5 years (because it is so good to me ) now we were in summer on vacation since I drove 1300km down and had hardly any oil cover about 0.5l , then we are there in the area driving about 300-450 km in the mountains in Bosnia and it was an outside temp of about 48 C° then the temp was getting warmer to shortly before the red un d then I stopped and looked after the oil that was on under min about 1-2cm we had to then still about 10 km until we were at ner tanke and there I then filled up the oil. about 1,5- 2 l it was. then everything was ok then on another day nen mountain drove up and there was the temp to the beginning of the red making hot have stopped oil that was ok and then let the engine cool down a little. there it was only on the fan wheel because the cage was off but had to go to the workshop because I had to cool down as unfortunately have found net. since they told me then that you should put on the head a little bit not immediately the complete seal change. would that bring what?? have now also light oil cover and also light cool water verb. however where we drove back was the hideout ok about 0,75 l au 1300 km but once went on the highway the oil control light at about 200kmh, have stopped immediately but the oil stand was ok. funny.. now I wonder if I have found the moto r in the summer should be overtaken in a specialized plant.. it is worth it with such a motor or could have the now bigger harm.. and how expensive would be such a thing and could one if one had to do the on has possibly equal to what the performance .. possibly other pistons etc.. thank you for your answer, hope I have explained it empathically..
