I have included three websites. Your question is quite general. There are details in these links that will answer many questions, such as:
1) What types of turtles were harmed?
2) How does oil harm the turtle?
3) What is the rehabilitation of an oiled turtle?
The timing of the oil spill has an impact on the damage done to turtle populations as if the spill occurs during the time of egg laying, there will fewer eggs.
I also note that turtles are more vulnerable than other mammals because they do not avoid water where spills have occurred.

There was no 'gulf stream oil spill' per say. Rather, the 2010 BP Gulf of Mexico oil spill has reached the Gulf. This spill started on 2010 April 20, reaching the gulf stream approximately in August.
