Help required regarding maintenance of diesel engine

I have a 2.0D corolla which i bought new in 2006. I have driven it carefully and throughout used Mobil Delvic 1 oil. Now it has done around 65K km. Though I do not feel any knocking or any problem in the car but I have noticed that it has started giving some black smoke when driven even with soft foot(though every diesel gives some smoke but I have felt it has increased). I took it to a mechanic and he checked it and said that "gari ka blow sahi ha aur mobil oil kum nahi kar rahi so it is fine".

I need advise on maintaince as I have not done any kind of nozel treatment or any thing of that sort uptil now.

I will highly appreciate if some one can help me and suggest me that should I use any sort of Injector cleaner or any thing of that sort and will it have any effect on the smoke and any negative effects of the cleaner etc.

Thanx in advance

I think that the injector nozzles and possibly the high pressure pump itself needs cleaning and adjustment. You could try a cleaner, but if the fuel economy is not dropping off, you could let it go for a little more mileage before getting the work done.
