Good day, 5 years ago we had a misconduct regarding our diesel vehicle. We had no experience with diesel and no questions about driving behaviour were asked. (New car!) Since we are driving almost only short distance, we now have problems with the combustion drives. These are of course often interrupted which we have to drive extra on the highway. Actually there is only the solution. Sales. I would like to have the tip: Which petroler is simply GUT ? It should e be in good used middle class/lower middle class car. Thanks in advance for tips.
