So little update I went with Motorcraft Oil figured I'd stay with stock oil (was on sale at walmart) and now I have a slight tick on start up :facepalm:. Never noticed it before, should I be worried? I am going to add another quart because I put 7 in and states takes 7.6 (could that .6 quarts cause the tick?) After going through what everyone recommends I missed that few people did say put 8 quarts!Cant seem to find it so I'll ask here if you don't mind sonicblewgt. I am considering going with royal purple 5w20? What are our guys thoughts would it be a waste of money or should I just stick to a cheaper brand? I also have a 2013 GT which this will be its second oil change it currently has 8,000 miles bought it with 6,900!
