Hello everyone, despite all negative reviews I bought 2 weeks ago a Opel Antara Cosmo 2.0 CDTI, year ́07, automatic, 150 hp. I have to say that I am very excited about the vehicle ! Well, I had a Opel Meriva before, you don’t have to say much anymore……… As far as consumption is concerned, I have to say that I am under 10 liters. I have now handled 2 full tank loads and did not handle the gas very gently 🙂 on the BC, 705 KM track indicated. I drove up to the light up of the tank lamp 670 KM and then refueled 53 liters. I think that I can still undercut this value if the Neulust has vanished and adapted to the driving style. I have read that you can achieve even better values in consumption and performance with a chip tuning. Do you have good experiences there? There are already tuning chips for self-assembly at ebay for 150 euros. Is this crap or are these Te and if you decide to install such a chip is not bad for the engine? After all, the engine has been driven like this for 5 years now.
