Brother first check your plugs and intake manifold. If the have mobil oil in them then yes your engine is weak. Im in the same situation as you are in. I have recently changed my pcv valve as @hash4u suggested. You can also get it changed it is very cheap. And then see the results. If not then replace the engine.
its simple, engine change kar do, purana sath do or 13000 mai bilkul fresh new jesa engine mill jata hai japanese, in standard without open & repaired.
Give us some details which engine oil are you using?
