Unhappy Update: Pictures added - Poured Synthetic diesel oil in my 2007 WRX STi - Stock

Subject : Subaru Wrx STi 2007 Stock 45,xxx miles

Made a stupid mistake and panicking about what I did.

I was such in rush that i bought 2 big jugs of Shell Rotella T6 5w40 Full synthetic for Diesel engines.

Poured 4.7 quarts of Shell Rotella T6 5w40 Full synthetic for diesel engines and have been driving for 200 miles so far. Have I caused any major damage to my turbo or engine? So far my mpg has decreased down to 15mpg.

I meant to buy Rotella T6 5W40 Synthetic for Gasoline Engines but i didn't take the time to read everything properly.

This is my plan, change my oil with the correct oil, change it again in 100 miles and replace it again in 200 miles.

What is the difference between regular Gasoline motor oil and diesel motor oil?

Thanks everyone.
