Patient: Merc 124 190E 2L petrol engine age:19 (1987 born) . He behave very well if we consider that he just return home successfully from a 2600 km holiday trip even that soon after the first 150 km he's got a virus, I suppose. So, he felt a bit tired especially in a hot day when the AC was going or when you need all his power in a passing up on the hills. I try to help giving him a bottle with injector’s cleaners but did not make any difference. Start is still ok at the first try but soon after if you push him hard black smoke started to come out. When engine is warm difficult to see the smoke but can not run more than 380-400 km with a full tank. so is very, very thirsty. Normally should drink 7.5-8 L/100 km but now is between 12 and 13. Not because I'm concern about creating a new petrol crises in the world but I'm afraid that all this liquid will go in his old joints and with a swollen knee is difficult to go more than 120 km/h. oil presure at start is right up at 3; the same while I'm driving exept the moments when is in iddle- goes down to 2-2.2, when accelerator pedal is depressed. I forgot to mention new fuel pump and new fuel filter about 5000 km ago; oil changed every 5000 km oil filter every 20000 km. Any sugestions? thanx
