Black Smoke in Vitz

I have 2007 model Toyota Vitz and it is installed with 3 cylinder 1kre-fe engine. I am basically facing two problems in my car. first it has low mileage and secondly it releases black smoke. Also it has a slight reduction in the pick of the car.
I took the injectors and MAP sensors to fix the mileage issue in the car and took uniformity tests on Ultrasonic injectors and injectors were all right when I cleaned the machine. There was an oily stuff in a very little amount and I used carb cleaner spray to clean it.
The spark plugs were working fine as I have changed them last month. All cylinders indicated the 130 psi upon ignition when I tested the pressure. The oil pressure was decreased to the middle of the dip stick. As mechanic recommended me to change the oil and then I started using the SAE-50 oil. Previously I was using the 10w-30.
After all, the smell of petrol is decreased but black smoke is still coming out. I will check it again to get any change in the fuel consumption of my car.
Kindly help me and guide me how can I resolve the issue of black smoke? I will be very thankful to you.
