Lancer Noob lol
 

Good day to all. My name is Josh. I am brand new here and I apologize if this post is in the wrong spot.

Yesterday I bought my first lancer. A 2014 ralliart. I am not new to Mitsubishi for I did own a 91 galant GSX but sadly that old girl had to be parted out.
Now that I am getting into a new car, I am hoping to learn as much as I can to keep her running for a very long time. She has only 50000km on her now and I am unsure of her past service history and the used car dealer ship didn't seem to know much about the car. What are some do's and don'ts about this car I should know. Where is a good source for DCT(dual clutch transmission) fluid that's not 50$ a liter. Along with anything else I should know.
I am a mechanic by trade but feel free to teach me anything of use

Not the wrong spot sort of, just not the busiest spot...
